Super Precision Angular Contact Ball Bearings S7020 CDGA/P4A

Super Precision Angular Contact Ball Bearings S7020 CDGA/P4A

The S7020 CDGA/P4A is a super precision angular contact ball bearing with a 100mm bore and 150mm outer diameter, crafted from high-quality chrome steel. It handles radial loads up to 18720 lbf and operates smoothly at speeds up to 10000 RPM.

Its sealed design keeps grease in and contaminants out, while the phenolic cage ensures quiet and efficient performance. The bearing works reliably in temperatures ranging from -30°C to 110°C.

With a 15° contact angle, it’s ideal for applications requiring high precision, such as machine tools or spindle drives. The extra light preload (Class A) ensures minimal friction and smooth operation.

Weighing 1.27kg, it’s robust yet manageable for its size. Compliant with P4A tolerance standards, it’s interchangeable with SKF bearings, making it a versatile choice for replacements or upgrades.

This bearing can be used in matched sets of three, arranged back-to-back, face-to-face, or tandem, offering flexibility for various load requirements. Perfect for demanding industrial or precision engineering tasks.
