Super Precision Angular Contact Ball Bearings S7019 ACDGA/HCP4A

Super Precision Angular Contact Ball Bearings S7019 ACDGA/HCP4A

The S7019 ACDGA/HCP4A is a super precision angular contact ball bearing with a 95mm bore and 145mm outer diameter, crafted from high-quality chrome steel and ceramic balls. It handles radial loads up to 17122 lbf and operates smoothly at speeds up to 15000 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 25° contact angle and extra light preload, it’s ideal for high-precision applications like machine tool spindles or high-speed robotics. The P4A tolerance class guarantees exceptional accuracy.

Weighing 1.01kg, it’s robust yet manageable for its size. This model is interchangeable with SKF bearings and can be paired in back-to-back, face-to-face, or tandem arrangements for versatile use.
