Super Precision Angular Contact Ball Bearings 7009 FEGA/HCP4A

Super Precision Angular Contact Ball Bearings 7009 FEGA/HCP4A

The 7009 FEGA/HCP4A is a super precision angular contact ball bearing with a 45mm bore and 75mm outer diameter, crafted from chrome steel for durability. Its 18° contact angle and ceramic balls ensure smooth operation under angular loads.

This bearing handles dynamic radial loads up to 2858 lbf and spins at remarkable speeds up to 46,000 RPM. The phenolic cage adds stability while keeping weight low at just 0.22kg.

Designed for extra light preload (Class A), it offers precise performance in demanding applications. The open seal allows easy lubrication and works in temperatures from -30°C to 110°C.

Ideal for high-speed machinery like spindles or robotics where precision is key. Compatible with SKF bearings and available in universal matching sets for back-to-back or face-to-face arrangements.
