Product families
Start with the conveyor interface, then narrow the chain family
Pallet and workpiece-carrier systems depend on the relationship between chain pitch, rollers, guide rails, sprockets, strand spacing and the underside of the carrier. Use the product families below to compare the architecture first, then open individual model pages for dimensions and RFQ data.

Free-flow conveying
Why Double Plus chain changes carrier speed and accumulation behavior
Double Plus chain uses a large roller together with smaller rollers. During conveying, the roller geometry creates a carrier speed that can be higher than the chain speed; during accumulation, the carrier can be stopped while the chain continues to move. The finished conveyor still depends on guide-rail geometry, stop design, load, lubrication and sprocket layout, so a model code should never be selected in isolation.
Applications
Move, buffer, locate and present carriers through automated processes
Typical projects include multi-station assembly, inspection and test, machine tending, controlled accumulation, lift-and-transfer interfaces and palletized workpiece handling. Each process changes the loading and stop sequence seen by the chain.
Review application engineering before choosing a chain family.
Engineering inputs that should be fixed before model selection
Carrier and payload
Record loaded carrier mass, underside contact surfaces, pallet dimensions, the number of carriers on the line and any process force applied while the pallet is stopped.
Chain and guide rail
Confirm pitch, roller arrangement, strand spacing, rail material, return support, conveyor center distance and the way the chain enters and leaves each sprocket.
Drive and station sequence
Define conveyor speed, starts per hour, accumulation zones, stop and locator sequence, transfer points, drive location, take-up travel and maintenance access.
Replacement work
Measure the installed system instead of matching by appearance
For an existing conveyor, send the visible chain code when available, several-pitch measurements, side and end photographs, sprocket tooth count and bore information, rail cross-section, strand center distance and a photograph of the carrier underside. These details help separate a true dimensional replacement from a visually similar chain.
If the machine drawing shows tolerances, special attachments, matched-strand requirements or a non-standard material, include the drawing with the RFQ.
Manufacturing, assembly and dimensional inspection
Inspection requirements should be agreed before production when the project calls for specific material documentation, dimensional records or product-specific inspection documents. For replacement chains, the most useful acceptance points are the dimensions and interfaces that can be compared with the installed sprocket, rail and carrier.
Order planning for engineering and production quantities
MOQ guidance: Standard parts normally follow a quantity MOQ, while high-value or large items can be evaluated by order value. Suitable new-customer samples of 1–5 pieces may be discussed at sample pricing. Different models can be combined toward approximately USD 1,500. Special materials or processes follow their production-batch MOQ. Routine consumer-style 1–2-piece retail orders are not accepted, while legitimate engineering or replacement requirements can be reviewed individually.
Standard parts are typically planned at 10–25 working days, customized components at 20–45 working days, and project equipment at 45–120 working days, subject to the final configuration and production review. Common trade terms include EXW, FOB, CIF and DAP; FCA, CFR, CPT, CIP and DDP can be discussed for a specific shipment.

Prepare a useful RFQ in one pass
Send the chain model or measured pitch, application, carrier/load information, quantity, sprocket data, rail/contact geometry, operating environment and any drawing or documentation requirement. That gives engineering enough context to review fit without turning the enquiry into a long back-and-forth exchange.
Company verification and project-document requirements can be included with the RFQ when they are relevant to the order.
