SKF - 71807 ACD/P4TBTM

Details

These sets of three matched super-precision angular contact ball bearings are available as universally matchable bearings or as preconfigured arrangements. Sets arranged in back-to-back and tandem, or face-to-face and tandem, are available in different preload classes and correct mounting results in preload within a predetermined range, without the need for shims or similar devices. Sets of three bearings paired in tandem need to be mounted against a single bearing, or another set of bearings in tandem, to achieve the desired preload. The bore and outside diameters of the bearings are matched to within a maximum of one-third of the permitted diameter tolerance, to provide better load distribution than single universally matchable bearings. Material : Constructed from high-quality bearing steel with a one-piece inner and outer ring and a plastic cage. Features are : Very High Running Accuracy, Very High Load Carrying Capacity, Low Heat Generation, Extended Service Life, Axial Stiffness. Applications : Machine Tool, Semiconductor Production, Textile Machinery, Medical & Laboratory Technology. ACD= 25° Contact Angle, P4= Dimensional & Running Accuracy To ISO Tolerance Class 4 (More Accurate Than P5)-Abec.7, TBTM= Set Of 3 Bearings Tandem – O-Arrangement, Medium Preload.
