Super Precision Angular Contact Ball Bearings 7026 CD/P4ADBD

Super Precision Angular Contact Ball Bearings 7026 CD/P4ADBD

The 7026 CD/P4ADBD is a super precision angular contact ball bearing with a 130mm bore and 200mm outer diameter, designed for heavy-duty applications. Made from chrome steel, it handles radial loads up to 54450 lbf and operates smoothly at speeds up to 11000 RPM.

Its 15° contact angle and matched arrangement (2 bearings DB) provide excellent stability under heavy preload. The phenolic cage ensures durability and reduces friction during high-speed rotations.

This bearing is ideal for precision machinery like CNC spindles or high-performance gearboxes. It works in temperatures from -30°C to 110°C and comes pre-lubricated for easy installation.

Weighing 6.47kg, it’s robust yet suitable for demanding industrial environments. Compliant with P4A tolerance standards, it’s interchangeable with SKF bearings for reliable replacements.
