Super Precision Angular Contact Ball Bearings 71810 CD/HCP4DBC

Super Precision Angular Contact Ball Bearings 71810 CD/HCP4DBC

The 71810 CD/HCP4DBC is a super precision angular contact ball bearing with a 50mm bore and 65mm outer diameter, measuring 14mm wide. Made from chrome steel and ceramic balls, it offers smooth operation and durability.

This bearing handles radial loads up to 2722 lbf and spins at speeds up to 46,000 RPM, thanks to its phenolic cage and moderate preload. The 15° contact angle ensures stability under angular loads.

Its open design allows easy lubrication, while the matched pair arrangement (DB) provides balanced performance. Ideal for high-speed applications like machine tool spindles or precision instruments.

Weighing just 0.092kg, it’s lightweight yet robust. Compliant with P4 tolerance standards for precise operation in temperatures from -30°C to 110°C.
