6319-2rs bearing price manufacturers

The 6319-2rs is a deep groove ball bearing with specific dimensions: 95mm (bore), 200mm (OD), and 45mm (width). The '2RS' suffix indicates dual-side rubber seals, which are critical for dustproofing and lubricant retention. You must verify the radial internal clearance (e.g., C3 for high-speed/high-temp applications) and the dynamic load rating (typically around 153-159 kN) to ensure it meets your machinery's operational requirements.

Insist on High-Carbon Chromium Steel (GCr15), which is the industry standard for wear resistance. For high-precision needs, check the ABEC rating (ISO P6 or P5). Professional buyers should request hardness test reports (HRC 60-65) and noise/vibration level testing (Z1V1 or Z2V2) to ensure smooth operation and a long service life.

Suppliers should strictly adhere to ISO 9001:2015 for quality management. For specific markets, ensure the product meets RoHS requirements (limiting hazardous substances). If the bearings are for the European market, CE marking may be relevant depending on the final machinery assembly, while IATF 16949 is essential if you are sourcing for the automotive supply chain.

Due to its large size and high load capacity, the 6319-2rs is commonly used in heavy-duty electric motors, agricultural machinery, mining equipment, and industrial gearboxes. Its sealed design makes it ideal for harsh environments where protection against contaminants like dirt and moisture is paramount.

Counterfeit bearings are a major risk in the B2B sector. Always verify the manufacturer's factory location and request a Certificate of Origin (CO). Use Made-in-China.com's 'Audited Supplier' reports to check the supplier's production capacity and business legitimacy. Avoid prices that are significantly lower (20%+) than the market average, as these often indicate recycled steel or poor heat treatment.

For 6319-2rs bearings, price is heavily influenced by raw material costs (steel indices). Negotiate based on annual volume rather than single orders to secure a 10-15% discount. If you are a new buyer, request a sample (usually 1-2 pieces) at a unit price, with the agreement that the sample cost will be deducted from the first bulk order.

Bearings are heavy and prone to rust. Ensure the supplier uses anti-rust oil coating and vacuum-sealed plastic packaging inside individual boxes. For sea freight, specify wooden crates (fumigated) or reinforced pallets to prevent box crushing. Ensure the Incoterms (e.g., FOB or CIF) are clearly defined in the contract to manage logistics risks effectively.

Utilize secure payment methods provided by reputable platforms like Made-in-China.com, which offer escrow-like services. Never wire full payments to private bank accounts. Implement a staged payment structure: 30% deposit and 70% balance against the Bill of Lading (B/L) or after a third-party pre-shipment inspection (PSI).
