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: | Max 10 MPa (static), dynamic loads depend on bearing type and size |
| other spec: | Max velocity: 5 m/s (standard), contamination resistance: IP54/IP65 sealing options |
| temperature: | -20°C to +80°C (standard), up to +120°C with special seals/lubrication |
Indicative industry ranges for design and RFQ preparation. Confirm the exact figures and applicable standard with the manufacturer before specifying.

A bearing block, also known as a slider, is the moving carriage that houses linear bearings. It supports the load, maintains bearing alignment, and enables smooth linear motion along a guide rail by converting rotational drive into precise linear movement.
Common materials include carbon steel, stainless steel, and aluminum alloy. The housing material may be specified as G20 cast iron per GB/T 9439, but confirm the exact material for your model.
Key parameters include bore diameter (8–50 mm), overall dimensions (height, width, length), dynamic and static load ratings (2.1–38.0 kN and 3.2–52.0 kN respectively), maximum speed (3–5 m/s), operating temperature (-20–80 °C), ingress protection (IP54–IP65), and weight (0.5–8.0 kg). Always verify these values with the manufacturer for your specific application.
Proper installation, lubrication, and sealing are essential. Regularly inspect for wear, noise, or increased friction. Contamination or inadequate lubrication can lead to premature failure, so follow the manufacturer's maintenance guidelines.
