Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.
This component is essential for the following industrial systems and equipment:
| pressure: | Up to 100 MPa static, 50 MPa dynamic |
| other spec: | Maximum rotational speed: 20,000 RPM (depending on size and lubrication) |
| temperature: | -40°C to +150°C (standard), up to +250°C with special materials |
Indicative industry ranges for design and RFQ preparation. Confirm the exact figures and applicable standard with the manufacturer before specifying.

Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The bearing system is available in standard metric series with bore diameters from 10 to 200 mm, outside diameters from 30 to 360 mm, and widths from 9 to 75 mm, per ISO 15. Other sizes may be available on request; confirm with the supplier.
Materials on file include high-carbon chromium steel (grade GCr15 per GB/T 18254), stainless steel, bronze alloys, and polymer composites. The specific material grade should be verified for the intended application.
Selection requires evaluating load ratings (dynamic and static), limiting speed, operating temperature, radial clearance, tolerance class, and vibration level against your bridge's operational requirements. Always verify these parameters with the legal manufacturer or supplier.
Relevant standards include ISO 15 for dimensions, ISO 76 for load ratings, ISO 15312 for speed and temperature, ISO 5753-1 for clearance, ISO 492 for tolerance, and ISO 15242 for vibration. These are reference standards; compliance must be confirmed with the supplier.
