Super Precision Angular Contact Ball Bearings 71915 CDGA/HCP4A

Super Precision Angular Contact Ball Bearings 71915 CDGA/HCP4A

The 71915 CDGA/HCP4A is a super precision angular contact ball bearing with a 75mm bore and 105mm outer diameter, crafted from durable chrome steel. Its compact 16mm width makes it suitable for tight spaces while maintaining high performance.

With a 15° contact angle and ceramic balls, it handles radial loads up to 8055 lbf and spins smoothly at speeds up to 36,000 RPM. The phenolic cage ensures quiet operation and longevity, even in demanding conditions.

Designed for extra light preload (Class A), it offers precise motion control in paired setups like back-to-back or face-to-face arrangements. The open seal allows easy relubrication, extending its service life.

Ideal for high-speed applications like machine tool spindles or precision instruments, it operates reliably between -30°C and 110°C. Weighing just 0.3kg, it’s lightweight yet robust for its size. Compliant with P4A tolerance standards for unmatched accuracy.
