Details

Double row angular contact ball bearings, with two-piece inner ring, correspond to a pair of single row angular contact ball bearings in a back-to-back arrangement, while requiring less axial space than the equivalent pair of single row angular contact ball bearings. The two-piece inner ring enables incorporation of a larger number of balls, with a larger contact angle, providing a high load carrying capacity, especially in the axial direction. Features are : Accommodate very high axial loads in both directions, radial loads, and tilting moments, Suitable where a stiff bearing arrangement is required, Separable design means outer ring with ball and cage assemblies can be mounted independently of the inner ring halves. Applications : Conveying equipment, Elevators and hoists, Agricultural machinery, Textile machinery, Machine tools, Pumps and compressors, Industrial gearboxes. D : Two-Piece Inner Ring And A 45° Contact Angle, MA : Pronged Machined Brass Cage, Outer Ring Centered.
