BS25-C206BR Double Plus Chain Steel Rollers

Configure BS25-C206BR for the conveyor, not only the chain code

BS25-C206BR Double Plus Chain Steel Rollers should be checked with sprocket pitch, rail contact, carrier underside, strand spacing, drive layout and operating environment. For replacement work, send the installed model, measured pitch, sprocket details and clear side/end photographs. For new equipment, send carrier mass, line speed, carrier count, start/stop sequence and station interfaces.

BS25-C206BR is a 2.5x double plus conveyor chain with steel rollers and a specified pitch of 19.05 mm. The model sits in the same speed-conveyor family as the plastic-roller versions, but the roller material is different and should be selected according to the actual conveyor rail, environment, load path and maintenance concept. The technical technical data provides a dedicated steel-roller dimensional row for this exact model. The current build therefore uses those exact dimensions and does not transfer values from a plastic-roller model. Because the available source page provides the dimensional drawing rather than a clean model photograph, this page is prepared as a draft with the technical drawing as its only image. It should be published after an exact or approved same-family steel-roller product photograph is added.

This model is most useful when it is treated as one element of the entire conveyor mechanism, not as an isolated replacement part. For BS25-C206BR, the 19.05 mm pitch must match the intended sprocket pitch and the rest of the chain path. The technical data also gives a large-roller diameter d8 of 18.3 mm and a pin diameter d2 of 3.28 mm. These are not decorative values: they affect the relationship between the chain, guide rails, carrier surface and sprocket engagement. The listed chain mass is 1.45 kg/m. That mass is useful when estimating the moving system, but it is not an allowable payload figure. Within the prepared range, BS25-C206BR is at the compact end of the selected pitch range. The next larger selected reference is BS25-C208AR, so buyers comparing these two should check not only pitch but also roller, pin and plate dimensions. A buyer evaluating an existing conveyor should therefore send the old chain code, measured pitch, clear photographs of the roller arrangement and the drive sprocket, and ideally a drawing of the pallet contact path.

Dimension drawing

Use this drawing together with the model table. Pitch, roller, pin and plate symbols are meaningful only when matched to the corresponding view.

Exact technical data for BS25-C206BR

All numerical values on this page are copied from the model-specific data row in the technical data available for this model. Fields that the technical data does not state are intentionally not filled with estimated values. This entry remains in draft status because a clean real product photograph for the exact/same approved family has not yet been added; the dimensional drawing is included for technical review.

Dimensions should be checked against the drawing before a replacement order is released. Symbols such as P, d1, d2, d4, d8, b1, b2, L, Lc, h2, T and t refer to the corresponding catalogue drawing for this chain family.

Where this chain fits in a pallet conveyor

A pallet conveyor chain has to work with the complete transport path. The chain engages the sprockets, follows the guide or wear rail, supports or drives the carrier through a defined roller interface, and then returns through the lower strand. The pallet or workpiece carrier may also meet stops, locators, lifts, transfers, sensors and process stations. For that reason, a correct chain model can still perform poorly if the rails are misaligned, if the sprocket tooth form does not match the chain, or if the carrier contacts the wrong roller surface.

Current conveyor-system terminology commonly describes pallet transport in terms of workpiece carriers, buffering, positioning, separation, locating stations, stops, merges and transfers. Those functions are system-level features. BS25-C206BR should therefore be selected from its specified geometry first, then checked against the required conveyor function. EVER POWER does not treat a catalogue tensile value or a family description as a substitute for a system calculation.

How to select BS25-C206BR

For a new conveyor, begin with the workpiece carrier and the required production sequence, then work outward to the chain path. For a replacement, begin with the installed chain and measure what is actually on the machine. In both cases, the objective is to remove ambiguity before production or shipment.

1. Confirm the exact pitch and compare every dimension that interfaces with the sprocket, guide rail, pallet or attachment hardware.
2. Identify the number of chain strands, center distance between strands, conveyor length, drive arrangement and take-up method.
3. Confirm whether the conveyor requires the 2.5x or 3.0x speed relationship and verify which roller material is specified by the rail design.
4. Provide pallet or workpiece-carrier mass together with the number of pallets that may be on the conveyor at one time; do not size from tensile strength alone.
5. Describe start/stop frequency, acceleration, indexing, any accumulation or hard-stop stations, and whether shock loading can occur.
6. State the operating environment, including temperature, dust, moisture, cleaning agents and lubrication restrictions.
7. For replacement work, include sprocket tooth count, bore/hub details and photographs or drawings so the chain-to-sprocket match can be reviewed.

When two models look similar in a photograph, use the dimensional table and drawing to separate them. A different pin length, roller diameter or plate depth can be enough to cause interference with a guide, misalignment with a sprocket or incorrect pallet contact. If measurements from the installed chain do not match the table, send those differences with the inquiry rather than forcing the nearest model number.

Sprocket, rail and conveyor integration

Chain and sprocket selection should be reviewed together. The sprocket pitch must correspond to the chain pitch, while tooth form, tooth count, bore, hub arrangement and shaft connection belong to the machine design. Reusing an old sprocket without checking its wear condition can shorten the service life of a new chain. Conversely, ordering a new sprocket from only a photograph can create a mismatch at the bore or hub even if the tooth pitch is correct.

The rail side of the system deserves the same attention. Check material, straightness, transitions, joints, return guides and the vertical position of every surface that contacts a roller. Pallet stops and locating devices should stop or locate the carrier without forcing the chain sideways. In multi-strand conveyors, keep the strands aligned and tensioned so one side does not pull the pallet ahead of the other. For longer systems, document the take-up travel and the method used to maintain chain length and tracking.

EVER POWER can quote matching sprockets and chain as a package when the sprocket requirements are provided. The companion sprocket is mentioned here because it is a functional partner to the chain; no bore, tooth count or hub dimensions are assumed from the chain model alone.

Installation and maintenance checkpoints

Before full-speed production, rotate or jog the conveyor through several complete chain circuits and inspect the engagement at drive, take-up and transfer points. Verify that connecting links, retaining parts and any chain-specific attachments are fully seated before the machine is placed into automatic operation. Keep the two sides of a twin-strand conveyor synchronized during installation so the pallet does not enter stations at an angle.

Pay particular attention to the roller/rail interface. A speed-conveyor chain relies on the installed geometry around the rollers, so contamination, damaged rail surfaces or incorrect pallet contact can change the behavior of the carrier even when the chain itself is dimensionally correct. Establish an inspection interval from the real duty cycle rather than using one universal schedule. A line that indexes continuously, operates in abrasive contamination or experiences frequent pallet stops may need more frequent checks than a lightly used transfer conveyor. Record elongation, roller condition, unusual noise, hot spots, sprocket wear and any recurring tracking correction so maintenance decisions are based on trend rather than guesswork.

Lubrication practice should follow the chain construction, environment and process restrictions. Avoid applying a lubricant simply because another chain on the same machine uses it. If the conveyor operates near sensitive products, cleaning agents, elevated temperature or a process that restricts oil, state that condition during the RFQ so an appropriate chain and maintenance approach can be discussed.

Customization and RFQ information

For an RFQ on BS25-C206BR, send the chain model if known, required quantity or length, destination country, machine application, conveyor speed, pallet or carrier details and any available drawing. Tell us whether the original design uses plastic or steel rollers and whether the required conveying ratio is 2.5x or 3.0x. If the request is a replacement for an installed chain, photographs of the complete chain, a close-up of one pitch, the sprocket and the rail interface are especially useful. EVER POWER can review the dimensional match and quote chain together with matching sprocket requirements when the sprocket data are available. Where the technical data do not define a property – for example a special material grade, attachment load, permissible working load or a particular coating – that property will be treated as an RFQ confirmation item rather than being assumed from the model family.

For production planning, also state whether you need endless matched lengths, loose chain lengths, connecting links, spare sections or sprockets. If the conveyor uses paired chains, tell us whether matched strand length is required. If a drawing contains tolerances or special interfaces not shown in the technical specification table, attach it to the inquiry. That information is more useful than a broad request for a “pallet conveyor chain” because it lets the quotation stay tied to the machine that will actually use the component.

Chain structure and mechanical interfaces

The working interfaces are the pins, bushings, rollers, side plates and family-specific support features. The rail should support the intended roller surface without forcing side plates to carry track load. Sprockets must belong to the same pitch system and the carrier should contact only the surfaces intended to support it. Misalignment can appear as noise, edge wear, stiff articulation or uneven load sharing between strands.

Application integration for pallet and workpiece carriers

This family is evaluated for palletized assembly, inspection, transfer and buffering where repeatable carrier motion matters. Coordinate stops, lifts, locators, sensors and transfers so process loads are reacted through fixtures rather than becoming unintended chain side loads. Accumulation or free-flow behavior is a system-level result.

Manufacturing and inspection points

Order release should check pitch consistency, roller and pin geometry, plate alignment, articulation, surface condition and the model dimensions that interface with the conveyor. If material certificates, inspection reports or order-specific compliance documents are required, list them in the enquiry before order acceptance.
