Application

Super Precision Angular Contact Ball Bearings S71902 CD/HCP4ADT are commonly used in high-speed machine spindles, where their ceramic balls and phenolic cage reduce friction and heat buildup. The 15° contact angle ensures stable performance under combined radial and axial loads.

In robotics, S71902 CD/HCP4ADT supports precise joint movements, thanks to its P4A tolerance class and matched bearing arrangement. The sealed design keeps contaminants out, extending service life in demanding environments.

For dental handpieces, S71902 CD/HCP4ADT’s grease lubrication and high-speed capability (up to 95,000 rpm) make it a reliable choice. The chrome steel rings provide durability, while the ceramic balls minimise vibration for smoother operation.

In optical equipment like lens positioning systems, S71902 CD/HCP4ADT’s preload adjustment ensures accurate alignment. The compact 15 mm×28 mm×14 mm size fits neatly into space-constrained designs without sacrificing performance.

For small electric motors, S71902 CD/HCP4ADT handles both radial and axial loads efficiently. The matched set configuration (2 bearings) improves load distribution, making it suitable for applications requiring balanced rotation.
