| 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.
