Super Precision Angular Contact Ball Bearings S7020 CD/P4ADT

Super Precision Angular Contact Ball Bearings S7020 CD/P4ADT

The S7020 CD/P4ADT is a super precision angular contact ball bearing with a 100mm bore and 150mm outer diameter, crafted from high-grade chrome steel. It handles radial loads up to 30375 lbf and operates smoothly at speeds up to 10000 RPM.

Its sealed design keeps lubrication in and contaminants out, while the phenolic cage ensures quiet, durable performance. The 15° contact angle and matched arrangement (2 bearings) provide excellent stability for precision applications.

This bearing is ideal for high-speed machinery like spindles or CNC equipment, where accuracy and reliability are crucial. It works in temperatures from -30°C to 110°C and comes pre-lubricated with grease for easy installation.

Weighing 2.55kg, 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.
