Manufacturer profiles associated with Precision Linear Guide / Bearing Block.
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.
It is used in machinery and equipment manufacturing for precise linear positioning and gap control, such as in automated assembly systems, measurement equipment, and machine tools.
Materials on file include high-carbon chromium bearing steel (e.g., GCr15/52100), case-hardened steel, and stainless steel for corrosion resistance. The specific material depends on the application requirements.
Accuracy grades range from C1 (highest precision) to C5 (standard). Choose a grade based on the required positioning repeatability and the application's tolerance. For example, C1 offers repeatability of ±0.001 mm, while C5 offers ±0.005 mm.
Regular lubrication is necessary, either grease or oil depending on speed and environment. Seals should be inspected for wear, and the rail and block should be kept clean to prevent contamination. Follow the manufacturer's maintenance guidelines.
