Loader slot bearings are generally recommended for applications with vibratory or static loads which produce small relative motion between the ball and race. Loader slots possess excellent ball-to-race conformity, which increases resistance to damage from vibration. When wear does occur, the ball can be replaced without removing the bearing assembly from the housing, which reduces downtime and lowers maintenance costs.
NHBB manufactures spherical loader slot bearings in sizes ranging from 0.5625 in. to 3.625 in. O.D. and two-piece rod end loader slots with head diameters from 0.680 in. to 2.681 in. O.D. Standard features include fully interchangeable Stellite® balls and Nitride (or Malcomize) spherical race I.D.s. Rod ends have male threads; keyways are optional.
