Steel-on-Steel Extended Inner Ring Series
Spherical Plain Bearings requiring
maintenance (steel-on-steel) have hardened sliding contact surfaces on both
rings. The surfaces are typically treated with molybdenum disulphide and
phosphate. It provides added wear
resistance and wear-corrosion. However,
Spherical Plain Bearings with this sliding contact surface combination require
regular relubrication. 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.
The Extended Inner Ring Series have been specially designed to eliminate the need for additional locational spacers. Also, to prevent excess bending stress, the inner ring bore is relieved.
AST has over 75 different Spherical Plain Bearings models composed of steel-on-steel with extended inner rings and are divided into the following series:
- GEWZ-ES Series – Steel-on-Steel, Inch Dimension, with lubrication groves, with extended inner rings
