KAA Black 90A PU-Coated Bearing Wheels
A polyurethane contact surface surrounds a steel ball bearing to form a compact, flat-tread rotating wheel. These components can serve as guide, contact or support wheels in a suitable mechanism. They are separate bearing wheels; an axle, bracket, drive motor and complete machine are not specified as included.
Construction and What to Select
| Item | Specification / selection |
|---|---|
| Offered coating | Black polyurethane, 90 Shore A on the individual model cards |
| PU type on cards | KAA-628-30×8-8 is labelled TPU; the other offered cards are labelled CPU. These designations are retained without assuming they are identical materials. |
| Bearing | Steel ball bearing; ZZ marking on the reviewed cards. Exact series and bore depend on model. |
| Offered dimensions | Outside diameter 22–110 mm; bore 8–50 mm; width 5–21 mm, in the combinations listed below. |
| Surface / construction | Flat PU tread around a bearing. This is a compact coated-bearing wheel family, distinct from the long dual-bearing roller family. |
| Supply | One selected bearing wheel. Group photographs illustrate the family rather than a multi-piece set. |
Model Code and Dimension Guide
The format KAA-bearing-D×d-W identifies the bearing series, outside diameter D, bore d and width W. For example, KAA-628-30×8-8 means bearing 628, outside diameter 30 mm, bore 8 mm and width 8 mm. The original photographs and black dimension lines are retained in the model images. Millimetres are the ordering dimensions; inch values are calculated using 25.4 mm per inch and rounded to three decimals. Any tolerance printed in an original drawing applies to that callout only.

What These Wheels Can Be Used For
| Use to evaluate | Function in a suitable design | Check before ordering |
|---|---|---|
| Machine guide / follower wheel | Provides a rotating PU contact surface against a rail, workpiece or guide. | Track shape, contact force, alignment, allowable compression and bearing support. |
| Material handling / contact roller | Supports or guides a moving part where a compact bearing wheel fits. | Load, speed, spacing, retention, surface sensitivity and available space. |
| Door / window or fixture mechanism | Can be evaluated as a component in a compatible sliding or guide arrangement. | The supplied material does not establish compatibility with any specific door, track, brand or machine. |
The source does not provide complete-wheel load, speed, temperature, wear-life or noise test ratings. Select the component from the actual operating requirements and confirm suitability for chemicals, contamination and temperature. A material or hardness label alone does not establish a machine rating.
Installation and Inspection
- Match all four selection fields: bearing series, outside diameter, bore and width. Check the bound dimension image against the available space.
- Confirm axle fit, bearing clearance, axial retention, spacers and the way the inner ring will be supported. Check shielding/sealing requirements for the operating environment.
- Use the correct bearing-ring support during assembly. Do not transmit installation force through the rolling elements or damage the PU surface.
- Align the wheel with its mating surface and check free rotation, rubbing, clearance and secure retention.
- Run a controlled installation check, then inspect contact behavior, tracking, heat, vibration and wear. Isolate equipment before adjustment or service.
Color and Family Reference Photographs
The available selections here are black 90A wheels. Original blue, yellow, red and natural-color family photographs explain the general coated-bearing construction and are labelled as references; they do not change the selected color, size, quantity or material. Their dimensions and bearing markings do not specify every offered model. No installed-machine application photograph is supplied for this group.
Other Sizes or Requirements
For a different coating, hardness, bore, bearing, width or mounting arrangement, send a complete dimensioned drawing, quantity and operating requirements to boltte@boltte.com. Confirm the exact configuration before ordering; one listed price is not a quotation for every custom configuration.
Original Product, Drawing and Application Images
The following source-faithful photographs show the selected black family, bearing construction and clearly labelled color references. Model-specific photographs and original dimension drawings for every available selection are in the upper product gallery.
