Dual Sealing and Long-Term Protection Pre-lubricated with high-performance grease, reducing friction and wear for medium-to-high-speed applications. Precision-ground raceways and balls ensure smooth and quiet operation, ideal for precision instruments and small motors. Made from chrome steel (GCr15) with strict heat treatment, providing high load capacity and durability.

Product Advantages and Features

  1. 1.Double Rubber Sealing Protection

    • Double-sided contact rubber seals (2RS) effectively block dust, dirt, and moisture, significantly extending service life in contaminated environments.

  2. 2.Pre-filled High-Performance Grease

    • Pre-lubricated with SKF premium grease to reduce friction and wear, supporting medium-to-high speeds with minimal maintenance.

  3. 3.Low Vibration and Quiet Operation

    • Precision-ground raceways and balls ensure smooth and quiet performance, ideal for precision instruments and household appliances.

  4. 4.Broad Temperature Tolerance

    • Operating temperature range: -40°C to +120°C (limited by seal and grease properties).

  5. 5.High Load Capacity and Durability

    • Made from high-purity chrome steel with specialized heat treatment, delivering excellent fatigue resistance and load capacity.
