Angular Contact Bearings 3906-2RS 3906 RS Bearing 3905 2RS Double Row Sealed Angular Contact Ball Bearings 304713 mm Bearings

BearingChromium Steel long-life bearings smooth and low noise.GeneralDouble row angular contact ball bearings provide the function of a pair of single row angular contact ball bearings arranged back-to-back but requiring less space.Double row angular contact bearings provide very stiff rigid bearing arrangements. They are also able to accommodate combined loads and are very suitable in supporting tilting moments.MisalignmentDouble row angular contact ball bearings must not be exposed to any misalignment.Minimum LoadBearings require a minimum load under all operating conditions to ensure kinematically correct rolling element function.For double row angular contact ball bearings the minimum load must be 1% of the dynamic load rating.Pruduct ApplicationsUltra Precision Surface Grinding Spindle Precision Surface Grinding Spindle Heavy-Duty Precision Boring Spindle Six-Spindle Automatic Screw Machine Ultra Precision Grinding Work-head Precision Tool-room Surface Grinder Spindle etc.
