Hollow Pin Conveyor Chains for pallet and workpiece-carrier conveyors

Hollow Pin Conveyor Chains provide a bore through the chain pin so cross rods, fixtures or other application-specific elements can be mounted through the chain. The base chain dimensions and the fixture design need to be reviewed separately so attachment loads are not assumed from the chain family name.

Family configuration

Select the base chain by pitch, roller, plate and sprocket geometry, then define the hollow-pin bore, cross-rod or fixture, support spacing and load path. For replacements, include an end view of the hollow pin and the attached hardware as well as the normal side-view chain measurements.

Start with the conveyor function and carrier interface, then compare the model drawing. For replacement work, use measured dimensions from the installed chain and sprocket rather than a visual match.

Machine interfaces to confirm before model selection

Pitch and strand geometry

Measure several pitches, confirm strand spacing and note whether the conveyor uses matched parallel strands. Record the installed sprocket tooth count and bore so engagement can be checked.

Roller and rail contact

Identify which roller or chain surface carries the load, rail width and material, return support and any side guide. Photograph the contact area when the conveyor is an existing machine.

Нижняя сторона носителя

Record the pallet contact surfaces, wear strips, locating features, center of gravity and any lift or transfer mechanism that changes how the carrier is supported.

Duty and environment

State conveyor speed, starts per hour, accumulation time, maximum queue, contamination, temperature, lubrication constraints and maintenance access.

Hollow Pin Conveyor Chains structure and interface drawing

Use the drawing to close the dimensional match

Model selection should move from system requirements to the exact chain geometry. Compare pitch, roller diameters and positions, pin diameter and length, plate height and thickness, and any special attachment or hollow-pin feature shown on the drawing. A match on pitch alone is not enough to approve interchangeability.

When dimensions are missing from an old machine record, measure the installed chain over several joints to reduce single-joint error, then add side and end photographs. If the sprocket is worn or is being replaced at the same time, include its tooth count, bore and hub arrangement in the review.

Applications and operating duty

Hollow Pin Conveyor Chains may be considered for palletized assembly, inspection, workpiece transfer, accumulation or machine-tending layouts when the chain architecture matches the rail and carrier design. The application name does not by itself confirm a model.

Describe loaded carrier mass, conveyor length, line speed, start/stop frequency and the number of carriers that can occupy the line. For accumulation, state queue length and release sequence. For locating or machining stations, identify the device that supports process forces so those loads are not unintentionally transferred through the conveyor chain.

Practical selection

Treat the cross rod or fixture as part of the machine design

The hollow pin provides an attachment interface, but it does not define the cross rod, fixture or force path. Specify rod diameter, unsupported span, retention method, material requirement and whether the rod rotates, slides or remains fixed. Check that retaining hardware clears the side plates, sprockets, rails and guards through the complete conveyor loop. If a rod spans between two chains, confirm strand centers and carrier stiffness so the rod is not forced to compensate for misalignment.

For replacement work, photograph the existing rod installation from the side and end and measure pin bore, chain pitch and plate geometry. For new equipment, add the fixture load, stop sequence and any process force applied to the attachment. Where practical, station loads should be reacted by dedicated supports rather than unintentionally through the chain attachment.

Commissioning and maintenance checks

After installation, run the line slowly without load and watch chain entry and exit at the sprockets, rail transitions, take-up travel and carrier tracking. Add representative pallets and confirm roller rotation, stop/release behavior and transfers before raising speed. Uneven tracking, scuffing, chain climbing, impact at transfers or different tension between parallel strands should be corrected before normal production use.

Maintenance should trend elongation over a defined number of pitches, roller condition, plate wear, rail wear, sprocket tooth condition and take-up position. Record the same measurement points each time so changes can be compared rather than relying on a single visual inspection.

FAQ and RFQ preparation

Can a visually similar chain be substituted?

Not on appearance alone. Compare the complete dimension set and the installed sprocket, rail and carrier interfaces before approving a replacement.

What photographs are useful?

Provide a side view of several pitches, an end view showing roller or hollow-pin position, the sprocket and the rail/contact surface. Add the model marking if it is still readable.

What should a new-system RFQ include?

Send carrier/load data, conveyor length and speed, process sequence, strand spacing, rail concept, drive/take-up layout, quantity and environment.

What should a replacement RFQ include?

Send installed model, measured dimensions, photographs, sprocket data, quantity and any special matched-length, attachment or material requirement.
