The S7020 CDGA/HCP4A is a super precision angular contact ball bearing with a 100mm bore and 150mm outer diameter, measuring 24mm wide. Made from chrome steel rings and ceramic balls, it offers high durability and smooth operation.
This bearing handles radial loads up to 18720 lbf and spins at speeds up to 10000 RPM, thanks to its phenolic cage and grease lubrication. Its 15° contact angle ensures stability under angular loads.
The sealed design keeps contaminants out, while the extra-light preload (Class A) minimises friction. It’s compatible with universal matching in back-to-back, face-to-face, or tandem arrangements.
Ideal for high-precision applications like machine tools or spindles, where low vibration and tight tolerances (P4A) are key. Weighing 1.06kg, it’s robust yet manageable for its size. Works in temperatures from -30°C to 110°C.
Interchangeable with SKF bearings, making replacements straightforward. Suitable for setups requiring matched sets of three bearings.
