Properties

  • • High load capacity – due to thin plastic intermediate layer.
    • Applicable in water, as COM-KU®/D doesn’t swell and the metal parts are produced from rust-free stainless steel.
    • Suitable at best for movements 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.
    • Large measurements are produced in parted models, inner diameter > 500 mm possible, see data sheet.
    • Through application of different plastic mixtures it is possible, to produce the special spherical plain bearings to the requested specifications.
  • • These spherical plain bearings are featured by sliding layers from special plastic COM-KU®/D.
    • This is a maintenance-free, compound plastic material, which in respect of wear, friction coefficient and capacity load, is among our best sliding materials.
    • The specific characteristic of this sliding bearing-plastic is based on the fact that even under high loads, largely no plastic deformation appears. Thereby this material finds its specific application at continuously high load.
    • Spherical plain bearings are produced predominantly in stainless steel in the bearing areas. But the use of different materials is possible.
    • As the plastic COM-KU®/D absorbs almost 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 bearing suggestive or necessary to prevent early wear.
    • As COM-KU®/D plastics are produced without phenolic resin, or similar hazardous materials these spherical plain bearings can be used for applications which have specific requirements concerning environmental compatibility.
