Stud type track roller SKF KR26PPA

Cam follower KR 26 PP A SKF Suitable accessories: NIP A1x4.5 press nipple, M 10x1 hexagon nut. SKF support rollers with a trunnion are designed on the basis of needle or cylindrical roller bearings. Instead of an inner ring, they are equipped with a trunnion with a threaded part. Support rollers with a trunnion are available in several versions and variants for various applications: 1) with or without a separator; 2) with trunnions of various designs: a) with a concentric seat, b) with an eccentric ring; 3) with several sealing solutions; 4) with a different profile of the working surface of the outer ring: a) a spherical shape in the standard version, b) a cylindrical shape. Unlike ball and roller bearings, in which the bearing size designates the diameter of the mounting hole d, for the rollers with a trunnion the dimension corresponds to the outer diameter D. Characteristics of the support rollers with the pin: 1) Capable of withstanding large radial loads, the thick-walled outer ring allows to withstand large radial load, reducing the magnitude of stresses from bending and deformation; 2) Capable of withstanding axial loads, the flange rings allow the support rollers with a trunnion to withstand axial loads due to misalignment or tipping moments; 3) Long service life, the spherical working surface of the outer ring has advantages in cases where it is possible to skew the outer ring relative to the guide surface, or to reduce the edge stresses; 4) Easy to install, the threaded part of the pin of the support rollers allows you to easily and quickly attach them to the relevant parts of the equipment with a hex nut.
