Description:

Spherical plain bearings requiring maintenance(steel-on-steel)generally have hardened sliding contact surface on both rings. The surfaces are treated with molybdenum disulphide and phosphated. It has characteristics of wear-resistance and wear-corrosion. Bearings with this sliding contact surface combination require regular re-lubrication. The high strength of the sliding contact surfaces makes these bearings especially suitable for bearing arrangements where heavy loads of alternating direction, shock loads or heavy static loads have to be accommodated.

With cylindrical extensions at each slide of inner ring.

Outer ring in chrome carbon steel, fractured, harden and phosphated.

Inner ring in chrome carbon steel, harden and phosphated.

2RS means bearings with seals on both ends.
