Knuckle PTEF Hydraulic Cylinders Ball Joint Bearing For Universal Vehicle

Spherical plain knuckle bearing for universal vehicle

Spherical plain bearings have an inner ring with a sphered convex outside diameter and an outer ring with a correspondingly sphered but concave inside surface. Their design makes them particularly suitable for bearing arrangements where alignment movements between shaft and housing have to be accommodated, or where oscillating or recurrent tilting or slewing movements must be possible at relatively slow sliding speeds.

Spherical plain bearings requiring maintenance have the sliding contact surface combination steel-on-steel. Bearings with this sliding contact surface combination require regular relubrication. The high wear resistance of the sliding 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. Bearings which have cylindrical extensions at both sides of the inner ring are intended for applications where normally spacer sleeves are arranged at either side of the bearing, or are specially designed for the bearing arrangements of hydraulic cylinders.

Applications of Spherical Plain Bearing: 

The applicability of this type is very extensive, and often ShS40 is indicated in the documentation for machines and equipment, although the more modern design of ShSP40 is more convenient for installation and operation. Of the common equipment units where it is installed, the following can be noted: an expanding fist of the MAZ brake system, tractor control drives, for example, TT-4M, a rotary cylinder and a drive gearbox of some BelAZ models, a hitch of tram cars, a torsion bar of combines and many other units of motor vehicles and various equipment.
