Super Precision Angular Contact Ball Bearings S7215 CDGA/P4A

Super Precision Angular Contact Ball Bearings S7215 CDGA/P4A

The S7215 CDGA/P4A is a super precision angular contact ball bearing with a 75mm bore and 130mm outer diameter, crafted from high-quality chrome steel. It features a 15° contact angle and comes sealed for protection, with an extra-light preload for smooth operation.

This bearing handles dynamic radial loads up to 16088 lbf and spins at speeds up to 28000 RPM, making it suitable for high-performance applications. Its phenolic cage ensures durability and reduces friction, while the grease lubrication simplifies maintenance.

Designed for angular contact loads, it works well in temperatures from -30°C to 110°C. The P4A tolerance class guarantees precision, and its universal matching capability allows flexible arrangements like back-to-back or face-to-face.

Weighing 1.23kg, it’s robust yet manageable for its size. Ideal for machine tools, spindles, or other precision machinery where accuracy and reliability are key. Interchangeable with SKF bearings, it’s a practical choice for replacements or upgrades.
