Super Precision Angular Contact Ball Bearings S7004 CEGA/P4A

Super Precision Angular Contact Ball Bearings S7004 CEGA/P4A

The S7004 CEGA/P4A is a super precision angular contact ball bearing with a 20mm bore and 42mm outer diameter, crafted from durable chrome steel. It handles radial loads up to 1667 lbf and spins smoothly at speeds up to 100,000 RPM.

Its sealed design keeps grease in and contaminants out, while the phenolic cage ensures quiet operation. The 15° contact angle makes it ideal for combined radial and thrust loads.

This bearing is part of a universal matching set, allowing back-to-back, face-to-face, or tandem arrangements. It’s interchangeable with SKF bearings, offering flexibility for replacements.

Weighing just 0.067kg, it’s lightweight yet robust. Perfect for high-speed applications like machine tool spindles or precision instruments, operating between -30°C to 110°C.
