SKF - 71908 ACB/HCP4AL

Details

These super-precision, high-speed, single row angular contact ball bearings, with 25° contact angle, accommodate radial and axial loads acting simultaneously, where the axial load acts in one direction only. Compared to the equivalent SKF E design high-speed bearings, these are suited for lighter loads. They have two lubrication holes, an annular groove, and two annular O-ring grooves in their outer rings. Features are: Suitable For Direct Oil-Air Lubrication, Very High Running Accuracy, Accommodate Very High Speeds, Reduced Stresses on Rolling Contact Surfaces. Applications : Machine Tool Spindles, Medical and Dental Equipment, Aerospace and Defense, Semiconductor Manufacturing. ACB= 25° Contact Angle, High-Speed B Design, HC= Bearing Or Bearing Components Of Ceramic, P4A= Dimensional Accuracy In Accordance With ISO Tolerance Class 4, Running Accuracy Better Than ISO Tolerance Class 4, L= Annular Groove With Two Lubrication Holes On The Non-Thrust Side Of The Outer Ring And Two Annular Grooves Fitted With O-Rings In The Outer Ring.
