Super Precision Angular Contact Ball Bearings S7030 CDGA/P4A

Super Precision Angular Contact Ball Bearings S7030 CDGA/P4A

The S7030 CDGA/P4A is a super precision angular contact ball bearing with a 150mm bore and 225mm outer diameter, crafted from high-quality chrome steel. Its 15° contact angle and sealed design ensure smooth operation under angular loads.

This bearing handles dynamic radial loads up to 38700 lbf and spins efficiently at speeds up to 11000 RPM. The phenolic cage offers durability while the grease lubrication simplifies maintenance.

With a P4A tolerance class, it delivers exceptional accuracy for demanding applications. The bearing works reliably in temperatures from -30°C to 110°C.

Ideal for precision machinery like spindles or CNC equipment, it can be arranged back-to-back, face-to-face, or tandem. Weighing 4.21kg, it’s robust yet manageable for its size. Interchangeable with SKF bearings for easy replacement.
