5M28T / 5M34T PU Timing-Belt Rollers, Single and Dual Pulley Ends

5M Timing-Belt PU Conveyor Rollers, Single and Dual Pulley Ends

These bearing-supported rollers combine a natural green-tinted polyurethane contact surface with toothed timing-pulley ends. They are components for a suitably designed conveying, feeding or synchronized-roller mechanism. An external compatible belt and drive arrangement are required where powered rotation is intended; a motor, belt, control system and complete conveyor are not included.

Choose the Correct Roller Family

Single or dual describes the number of timing-pulley ends, not the bearing quantity. Select the actual pulley layout and exact dimension image for the installation. The code's bearing reference does not replace a complete bearing/retention specification for a custom revision.

Dimension Guide: Contact Length and Total Assembly Length

The nominal D×L fields in the model identify PU contact diameter D and nominal coated/contact length L. Pulley ends extend beyond that contact length: the total assembly length is a separate callout in the original drawing. For example, the ACL 50×100 reference drawing shows a 100 mm contact dimension and a 123 mm overall callout. Do not use nominal contact length as the end-to-end mounting space.

Millimetres are the ordering dimensions. Inch values are calculated using 25.4 mm per inch and rounded to three decimals. Preserve the drawing's separate seat, bore, retention and tolerance callouts when confirming a finished assembly; do not apply a tolerance from one feature to every dimension.

Construction and Supplied Scope

What These Rollers Can Do

These are not a complete drive system. The supplied material does not establish rated torque, complete-roller radial/axial load, maximum speed, noise level, temperature range, runout or service life. Select the roller and belt system for the actual load, support span, shaft stiffness, environment and duty.

Installation and Selection Checklist

1. Match family, contact OD, nominal contact length, bore, model bearing reference, tooth count and single/dual pulley layout.
2. Use the original dimension image to verify total length, pulley extension, bearing seats, retention and available mounting space.
3. Confirm the matching 5M belt tooth form and working width, alignment, wrap and controlled tension. Establish permissible belt and bearing loads for the design.
4. Check shaft fit, bearing support, spacers and axial retention. Apply assembly force through the correct bearing ring and protect the PU surface.
5. Guard the transmission and test under controlled conditions, inspecting tracking, speed relationship, free rotation, heat, vibration and wear. Isolate equipment before adjustment or service.

Other Lengths, Shafts or Materials

For a shaft assembly or a configuration not listed, send a complete dimensioned drawing with all shaft ends, total length, bearing arrangement, material, belt requirements, quantity, load, speed and environment to boltte@boltte.com. Confirm the finished configuration and supplied scope before ordering. A generic other-size amount is not a quotation for every custom assembly.

Original Product, Drawing and Application Images

The translated original photographs show the pulley ends, bearing openings, PU surface and size-family arrangements. Original drawing geometry and dimension lines are retained in every offered model image in the upper gallery. No installed-machine application photograph is supplied for this group; the application functions and selection checks are described above.
