Steel-on-Steel Extended Inner Ring Series

CAD drawing of a Steel-on-Steel Extended Inner Spherical Plain Radial Bearing from AST BearingsSpherical 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
  • GEWZ-ES-2RS Series – Steel-on-Steel, Inch Dimension, with Seals, with lubrication groves, with extended inner rings
  • GEEW-E Series – Steel-on-Steel, Metric Dimension, with extended inner rings
  • GEEM-ES Series – Steel-on-Steel, Metric Dimension, with lubrication groves, with extended inner rings
  • GEEM -ES-2RS Series – Steel-on-Steel, Metric Dimension, with Seals, with lubrication groves, with extended inner rings
