Technical Specifications: T52BW and H140 The universal designs T52BW and H140 combine the special requirements for spherical roller bearings of outside diameter 320 mm and larger in paper machines. It brings together design variants in technical specifications that cover most of the bearing locations in the paper equipment. • T52BW is used as a universal design in tapered and straight bore spherical roller bearings • H140 is used as a universal design in straight bore spherical roller bearings and includes T52BW as well as H44SA and H44SB

H40AB 6 lubricating holes in the inner ring H40AC H40AB + lubricating groove in the inner ring H44SB H40AC + 6 aluminum plugs for closing lubricating holes in inner ring H140 Standard Lubricating groove and 3 lubricating holes in the outer ring H44SA 3 aluminum plugs for closing lubricating holes in outer ring T52BW Use of one suffix for most bearing applications J26C Point of max. radial runout marked on inner and outer ring allows for reduced inventory P5 running accuracy for inner and outer ring & increased availability
