Hollow Pin Conveyor Chains

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.

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.

Documentation and release package

Before releasing a replacement or new-system order, keep the dimensional match and the commercial request in the same project record. Record the selected model, several-pitch measurement where applicable, roller or pin arrangement, strand spacing, sprocket tooth count and bore, rail/contact geometry and carrier underside. Add the operating inputs that cannot be read from the chain itself: loaded carrier mass, line speed, starts per hour, maximum accumulation, transfers, contamination and lubrication constraints.

For a replacement, photographs should show more than the chain on a bench. Include a side view of several pitches, an end view that shows roller position, the sprocket and shaft arrangement, the rail surface and the carrier interface. If a failure or abnormal wear triggered the replacement, mark the location on the conveyor and record whether the symptom appears under load, during accumulation, at restart or at a transfer. This helps distinguish an identification problem from an alignment, lubrication or station-interface problem.

For procurement, state quantity, required delivery destination, any matched-strand or special-length requirement and the documents that must accompany the order. Product-specific inspection reports, material documents or compliance records should be requested at quotation stage so the available document set can be confirmed before production. Unsupported material grades, coatings, allowable loads or special tolerances remain engineering confirmation items rather than assumptions based on a neighboring model.
