Special spherical plain bearings GE822 ND/HD

Special spherical plain bearings with maintenance-free inner ring

TECHNICAL DETAILS Special spherical plain bearings GE822 ND/HD

  • Stainless steel outer ring / COM-KU®/D inner ring * also available with inner ring from stainless steel.
  • ISO 6124 (ND Serie) and ISO 6124/3 (HD Serie)
  • maintenance-free
  • Interchangeable with other DIN spherical plain bearings
  • Suitable for water and sea water applications.
  • There is no harming of the environment by this sliding material.


  • • Stainless steel outer and inner ring with COM-KU®/D sliding layer.
    • High load capacity due to thin plastic intermediate layer.
    • Well suitable for movement which occur only in long intervals.
    • The non-ageing sliding layer prevents adhesion of the parts and guarantees therefore a faultless and long-term functionality of the bearing.
    • For large measuremts, the outer ring is executed as a splitted version. Inner diameter >500 mm possible.
    • Many special designs are possible.
    • By usage of different plastic mixtures, there is the possibility to produce special bearings according to customer specifications.
  • • These spherical bearings are featured by sliding layers from special plastic COM-KU®/D. This is a maintenance-free compound plastic material, which is relating to war, friction coefficient and capacity load one of our best sliding materials.
    • The special characteristic of this sliding bearing-plastic based on the fact that even under high loads, largely no plastic deformation appears.
    • The bearing is mostly from stainless steel. Other materials are possible.
    • As the plastic COM-KU®/D almost absorbs no humidity nor shows any swell behaviour, it can be applied without specific constrictions or additional sealing in most of the liquid mediums in connection with stainless steel.
    • Only at very abrasive mediums is sealing of the baring suggestive or necessary to prevent early wear.
    • As COM-KU®/D plastics are produced without phenolic resin or similar hazardous materials, these spherical bearings can be used for applications which have specific requirements concerning environmental compatibility.


  • Stainless steel with COM-KU®/D for sliding material*


  • Housing Ø in accordance with customer specification
  • Bushing inner-Ø after mounting in accordance with customer specification
  • Shaft tolerance in accordance with customer specification


  • The bearings are maintencance-free. There is no lubrication necessary.
