ABK Red 50A PU Dual-Bearing Idler Rollers, 10–30 mm

ABK Red 50A PU Bearing-Supported Idler Rollers

These unpowered rollers combine a red polyurethane contact surface with a steel core and a bearing-supported bore. They serve as guide, contact or idler components in a suitably designed conveying or machine mechanism. The supplied family construction shows two bearings; match the exact bearing and bore of the selected model.

Construction and Supplied Scope

Choose the Exact Model

ABK-D×L-bearing-bore identifies the outside diameter, roller length, bearing series and configured bore in millimetres. Select all four fields together. Some source names mention possible alternative bores; this listing offers only the bore printed in the selected model and its bound dimension image. Other bore sizes require a separately confirmed configuration.

Millimetres are the ordering dimensions. Inch values use 25.4 mm per inch, rounded to three decimals. The source model photographs illustrate the family and are reused across sizes; the printed dimensions and model identify each configuration.

Available Models, Dimensions and Original Prices

What These Rollers Are Used For

The source does not establish a complete-roller load rating, maximum speed, temperature limit, runout, noise reduction or service life. The 50A material reference alone does not establish suitability for every surface or duty. Evaluate contamination, chemicals, contact pressure and workpiece finish for the actual application.

Installation and Maintenance

1. Match OD, length, bearing series and bore to the original dimension image and available mounting envelope.
2. Check shaft fit, bearing support, shoulders, spacers and axial retention. Do not clamp or load the bearing arrangement unintentionally.
3. Support the correct bearing ring during assembly and protect the PU surface from cuts, solvents and excessive installation force.
4. Align the roller and test free rotation, contact tracking, clearance, bearing heat, vibration and wear under controlled conditions.
5. Guard moving parts and isolate the machine before service. Replace damaged PU or rough/noisy bearings as required by the machine maintenance plan.

Other Bores and Custom Sizes

For other bore sizes, lengths, coatings or shaft assemblies, send a dimensioned drawing, bearing requirements, load, speed, environment and quantity to boltte@boltte.com. Confirm the finished configuration and supplied scope before ordering. An unspecified other-size amount is not a quotation for every custom assembly.

Original Product, Drawing and Application Images

The translated original images retain the product surfaces, bearing faces and original dimension lines. Open bearing seats and loose bearings in family photographs are construction references; the selected model defines the configured bearing arrangement. The green roller is an expressly labelled other-color reference, not a red-model option. Storage photographs are context only. No installed-machine application photograph is supplied; application functions and selection checks are explained above.
