Features
Deep groove ball bearings are versatile, self-retaining bearings with solid outer rings, inner rings and ball and cage assemblies. These products, which are of simple design, robust in operation and
easy to maintain, are available in single and double row designs and in open and sealed variants. Due to the manufacturing processes used, open bearings can have turned recesses in the outer ring for
seals or shields. Due to their low frictional torque, deep groove ball bearings are suitable for high speeds.
Operating temperature
Deep groove ball bearings without seals can be used up to an operating temperature of +120 °C. For applications at temperatures above +120 °C, please contact us. Bearings with a diameter D of more than 240 mm are dimensionally stable up to +200 °C.Deep groove ball bearings with lip seals can be used at operating temperatures from –30 °C to +110 °C, limited by the grease and sealing ring aterial.
Bearings with gap seals can be used from –30 °C to +120 °C
Caution!
Bearings with cages made from glass fibre reinforced polyamide are suitable for operating emperatures up to +120 °C.
Minimum radial load
In order to ensure slippage-free operation, the bearings must be subjected to a minimum radial load. This applies particularly in the case of high speeds and high accelerations. In continuous operation, a minimum radial load of the order of P/Cr 0,01 is necessary for ball bearings with cage.
Mounting dimensions
The dimension tables give the maximum radius dimension ra and the diameters of the abutment shoulders Da, da.
