High Precision R8 Series Deep Groove Ball Bearings – Built for Performance & Durability
Engineered with premium-grade chrome steel for superior hardness and corrosion resistance, these R8 ball bearings deliver unmatched rotational accuracy under heavy loads. The deep groove design ensures optimal radial and axial load distribution, minimizing friction for smooth operation. Choose from multiple sealing options (R8, R8RS, R8-2RS, R8Z, R8ZZ, R8-2Z) to match your environment—dustproof (Z/ZZ), rubber-sealed (RS/2RS), or open (R8). Precision-polished raceways and Grade 25 chrome steel balls reduce vibration, extending lifespan even in high-speed applications (up to 15,000 RPM).
Ideal for:
Industrial machinery, electric motors, conveyor systems, automotive parts, and DIY tools. Compact dimensions (1/2"x1 1/8"x1/4") ensure compatibility with standard equipment.
