Where alternative parts are offered, we make no claims as to their suitability. Selection of the most suitable bearings and parts is the responsibility of the customer. We recommend you replace bearings with the same type if that type is working well. High speed caged bearings are better suited to handle vibration than standard caged bearings.
DIN 3760 - High Temperature and chemical resistance.
Operating Temp. Range: -20oC to +240oC. The rubber elastomer outer covering tolerates thermal expansion as well as roughness in the housing bore. Suitable for synthetic and hydraulic fluids, strong acids, steam, many chemicals and many alkalis.
DIN 3760 - General purpose grease and oil sealing. Note - metal cased and rubber cased seals may be interchanged at our discretion. If one or the other is specifically required please let us know when ordering.
Operating Temp. Range: -30oC to +90oC. The rubber elastomer outer covering tolerates thermal expansion as well as roughness in the housing bore. Excellent resistance to mineral oil based fluids, hydrocarbon fuels, greases and water. Not suitable for aromatic hydrocarbons, chlorinated hydrocarbons, brake fluid and some fire resistant hydraulic fluids.
