The 7017 CD/P4ADBB is a super precision angular contact ball bearing with an 85mm bore and 130mm outer diameter, crafted from high-grade chrome steel. Its 15° contact angle and matched pair design (DB arrangement) ensure smooth handling of combined radial and axial loads.
With a dynamic radial load capacity of 24975 lbf and speeds up to 28000 RPM, it performs reliably in demanding conditions. The phenolic cage reduces friction, while the open design allows for easy relubrication.
This bearing is ideal for high-precision applications like machine tool spindles or high-speed robotics. Its P4A tolerance class guarantees exceptional accuracy, and the light preload (Class B) ensures smooth operation.
Weighing 1.79kg per set, these bearings are robust yet manageable for their size. They’re interchangeable with SKF equivalents, simplifying replacements. Suitable for temperatures from -30°C to 110°C.
