Super Precision Angular Contact Ball Bearings 708 CEGA/HCP4A

Super Precision Angular Contact Ball Bearings 708 CEGA/HCP4A

The 708 CEGA/HCP4A is a super precision angular contact ball bearing with an 8mm bore and 22mm outer diameter, crafted from chrome steel for durability. It features a 15° contact angle and ceramic balls for smooth operation.

With a dynamic radial load capacity of 526 lbf, it spins efficiently at speeds up to 100,000 RPM. The phenolic cage ensures stability, while the open design allows easy lubrication.

Its extra-light preload (Class A) and P4A tolerance class make it ideal for high-precision applications. Suitable for use in pairs (back-to-back, face-to-face, or tandem arrangements).

Perfect for CNC spindles or high-speed machinery where accuracy and speed are crucial. Weighing just 0.011kg, it’s lightweight yet robust for its size. Works in temperatures from -30°C to 110°C.
