Super Precision Angular Contact Ball Bearings S7008 FE/P4ADBA

Super Precision Angular Contact Ball Bearings S7008 FE/P4ADBA

The S7008 FE/P4ADBA is a super precision angular contact ball bearing with a 40mm bore and 68mm outer diameter, crafted from durable chrome steel. It features a sealed design and comes as a matched pair for extra stability.

With an 18° contact angle, it handles both radial and axial loads efficiently, supporting up to 4388 lbf dynamically. It spins smoothly at speeds up to 41,000 RPM, thanks to its phenolic cage and grease lubrication.

The extra-light preload ensures minimal friction, making it ideal for high-precision applications. Its P4A tolerance class guarantees consistent performance in demanding conditions.

Perfect for machine tools or spindle systems where accuracy and speed are crucial. The matched pair setup simplifies installation, while the sealed design keeps contaminants out. Works reliably in temperatures from -30°C to 110°C.
