Ball bearing 6201-2rs manufacturers

The 6201-2RS is a deep groove ball bearing with a 12mm bore, 32mm outer diameter, and 10mm width. The '2RS' suffix indicates dual-lip rubber seals on both sides, which provide superior protection against dust and moisture compared to metal shields (ZZ). Buyers must specify the Clearance Class (e.g., C3 for high-speed/high-heat applications) and the Precision Grade (ISO P6/ABEC-3 or P5/ABEC-5) to ensure compatibility with their specific machinery.

High-quality 6201-2RS bearings should be manufactured from GCr15 High-Carbon Chromium Steel (SAE 52100). Ensure the supplier provides a Hardness Test Report (typically HRC 60-65). For specialized environments, verify the grease type used (e.g., Kyodo Yushi or Shell) as it determines the operating temperature range (-20°C to +120°C) and the service life of the bearing.

Suppliers should strictly adhere to ISO 9001:2015 for quality management. For exports to the EU, RoHS and REACH compliance are essential to ensure the absence of hazardous substances in the seals and lubricants. If the bearings are intended for the automotive aftermarket, look for manufacturers certified under IATF 16949.

This specific model is highly versatile, commonly used in electric motors, household appliances (like washing machines), power tools, and automotive alternators. Because of its sealed design, it is the preferred choice for environments where contamination prevention and maintenance-free operation are priorities.

Counterfeit bearings are a significant risk in the B2B sector. Always request a Material Mill Certificate and use Made-in-China.com's 'Audited Supplier' reports to verify the factory's production capacity. Conduct a third-party pre-shipment inspection (PSI) to test noise levels (Z-grade) and vibration levels (V-grade) before final payment.

Bearings are commodity items where price is heavily influenced by raw material (steel) indices. Negotiate based on annual volume rather than single orders to secure lower unit prices. For 6201-2RS, a standard MOQ is often 500-1,000 pieces, but you can request tiered pricing where a 20% discount is typically achievable at the 5,000+ unit threshold.

Bearings are heavy and prone to corrosion if exposed to sea air. Ensure the supplier uses anti-rust oil coating, individual plastic bagging, and industrial-strength multi-layer cartons. For sea freight, insist on palletization with shrink-wrap to prevent moisture ingress and handling damage during transit to your specific country.

Utilize Secured Trading Services provided by platforms like Made-in-China.com to ensure your payment is only released after the goods have been shipped and verified. Avoid direct wire transfers to private accounts; always use corporate accounts verified by the platform to ensure alignment with international trade policies.
