Maintenance Required, Rectangular Segment Welded Rod Segment Rod End Bearing

These SKF rod end bearings contain spherical plain bearings with a steel-to-steel sliding contact surface combination. The bearings require maintenance and can be supplementally lubricated by means of grease nipples on the rod ends and shanks. Rod ends with welded rods of rectangular cross-section can withstand high static loads.

Suitable for static, alternating or shock loads.
Easy to relubricate
Replaceable bearings
