01. Precision Under High-Speed Operation

With available contact angles (15° C, 25° AC, or 40° B), the 7002 Series is optimized for high-speed applications, providing excellent rigidity, reduced heat generation, and smooth running accuracy for precision equipment.

02. Enhanced Running Accuracy & Low Noise

Crafted from high-grade chrome steel and offered in elevated P5 and P4 precision classes, these bearings ensure minimal vibration, consistent performance, and extended lifespan in demanding precision environments.

03. Versatile Sealing & Configuration Options

Available in open, shielded (ZZ), or sealed (2RS) designs to suit various operational environments. Supports single or paired mounting for adjustable preload and stiffness, ideal for clean, lubricated, or lightly contaminated conditions.

Design & Configuration

The 7002 bearing is commonly supplied in an open configuration to allow customized lubrication. Steel shields (ZZ) offer protection against dust and debris, while rubber seals (2RS) provide a maintenance-free solution for sealed applications. Engineers can choose the contact angle to optimize performance: 15° (C) for very high speeds, 25° (AC) for balanced load and speed, or 40° (B) for increased axial rigidity.

“In precision spindles and high-speed electric motors, the 7002 AC bearing is recognized for its reliable performance, low friction, and ability to maintain accuracy under rotational stress.”
