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 10-15 MPa static load capacity, dynamic loads typically 30-50% lower |
| other spec: | Max velocity: 2-5 m/s depending on size and lubrication, contamination sensitivity: IP54-IP67 protection available |
| temperature: | -20°C to +80°C (standard), up to +150°C with special seals/lubricants |
Indicative industry ranges for design and RFQ preparation. Confirm the exact figures and applicable standard with the manufacturer before specifying.

CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
Linear guides/bearings are used in machinery and equipment that require precise linear motion, such as CNC machines, automation systems, and leaf drive mechanisms. They provide stable and low-friction movement for carriages or sliding elements.
Selection should be based on load requirements, speed, accuracy, operating environment, and mounting constraints. Refer to the parameters such as rail width, length, dynamic/static load ratings, accuracy grade, and preload class. Always verify model-specific values with the manufacturer or supplier.
Regular maintenance includes checking and replenishing lubrication (grease or oil), inspecting seals for damage, and cleaning any contamination. Monitor for increased friction, noise, or play, which may indicate wear or misalignment. Follow the manufacturer's maintenance schedule.
Relevant standards include ISO 14728-1 for dynamic and static load ratings, and ISO 14728-2 for accuracy grades and running parallelism. These standards provide testing methods and tolerance classes. Compliance should be verified with the manufacturer.
