Super Precision Angular Contact Ball Bearings 7009 CE/HCP4AQBCA

Super Precision Angular Contact Ball Bearings 7009 CE/HCP4AQBCA

The 7009 CE/HCP4AQBCA is a super precision angular contact ball bearing with a 45mm bore and 75mm outer diameter, crafted from high-quality chrome steel. It features a 15° contact angle and comes in a matched set of four bearings for balanced performance.

This bearing handles radial loads up to 7605 lbf and spins at speeds up to 46,000 RPM, thanks to its ceramic balls and phenolic cage. Its extra-light preload ensures smooth operation with minimal friction.

The open design allows for easy lubrication, while the P4A tolerance class guarantees precision. Ideal for high-speed applications like machine tool spindles or precision instruments.

Weighing 0.89kg, it’s robust yet manageable for its size. The matched set arrangement (QBC) ensures consistent performance across all four bearings. Suitable for temperatures from -30°C to 110°C.
