Super Precision Angular Contact Ball Bearings 7015 CEGA/P4A

Super Precision Angular Contact Ball Bearings 7015 CEGA/P4A

The 7015 CEGA/P4A is a super precision angular contact ball bearing with a 75mm bore and 115mm outer diameter, crafted from high-quality chrome steel. It features a 15° contact angle and is designed for angular contact loads, handling up to 5850 lbf dynamically.

Its open design and phenolic cage ensure smooth operation at speeds up to 24,000 RPM, even in temperatures ranging from -30°C to 110°C. The extra light preload (Class A) enhances precision and reduces friction.

This bearing is ideal for high-speed applications like machine tool spindles or precision instruments. Its universal matching capability allows flexible arrangements (back-to-back, face-to-face, or tandem).

Weighing 0.65kg, it’s robust yet manageable for its size. Compliant with P4A tolerance standards, it’s interchangeable with SKF bearings for easy replacements.
