TECHNICAL DATA SPECIAL SPHER. PLAIN BEARINGS

  • With COM-KU®/D sliding layer
  • All COM-KU®/D type spherical plain bearings are maintenance-free.
  • Standard production according to DIN (ND series or HD series)
  • Special measurements and designs are produced at short notice!
  • This sliding material causes no threat to health and environment!
PROPERTIES
  • Stainless steel outer and inner ring, with COM-KU®/D sliding layer.
  • Maintenance-free, no lubrication necessary
  • High load capacity - due to thin plastic intermediate layer.
  • Compatible with all DIN - spherical plain bearings
  • 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.
  • Application at e.g. valve, barrage assets, ball valves, guide vane bearings, dampers, etc.
  • Large measurements are produced in parted models, inner diameter > 500 mm possible, see data sheet.
  • Many specials designs are possible beyond standard measurements.
  • Through application of different plastic mixtures it is possible, to produce the special spherical plain bearings to the requested specifications.
DESCRIPTION
  • The bearings are produced in two standard designs, according to ISO 6124 (ND series) and ISO 6124/3 (HD series).
  • 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.
