Super Precision Angular Contact Ball Bearings S7004 CE/HCP4ADBB

Super Precision Angular Contact Ball Bearings S7004 CE/HCP4ADBB

The S7004 CE/HCP4ADBB is a super precision angular contact ball bearing with a 20mm bore and 42mm outer diameter, designed for high-speed applications. It features a 15° contact angle and comes as a matched pair (DB arrangement) for balanced performance.

Made from chrome steel rings and ceramic balls, it handles dynamic radial loads up to 2722 lbf and spins smoothly at 100,000 RPM. The phenolic cage and sealed design ensure low friction and long service life.

Preloaded for light operation, this bearing excels in precision machinery like CNC spindles or dental drills. Its compact size (24mm width) and 0.12kg weight make it ideal for space-sensitive setups.

Operating between -30°C to 110°C, it’s lubricated with grease for maintenance-free use. The P4A tolerance class guarantees consistent accuracy under demanding conditions.
