Super Precision Angular Contact Ball Bearings S71914 CD/P4ADBA

Super Precision Angular Contact Ball Bearings S71914 CD/P4ADBA

The S71914 CD/P4ADBA is a super precision angular contact ball bearing with a 70mm bore and 100mm outer diameter, crafted from durable chrome steel. Its compact size (70mm×100mm×32mm) makes it suitable for tight spaces while maintaining high performance.

This bearing handles radial loads up to 12578 lbf and spins smoothly at speeds up to 28,000 RPM. The 15° contact angle and extra-light preload ensure precise operation, ideal for demanding applications.

Sealed for protection and lubricated with grease, it requires minimal maintenance. The phenolic cage enhances durability and reduces friction, extending service life.

Perfect for high-precision machinery like spindles or CNC equipment, it operates reliably in temperatures from -30°C to 110°C. The matched pair (2 bearings) offers balanced performance for angular contact loads. Weighing 0.67kg, it’s robust yet manageable for its size.
