6) SUGGESTIONS

a) MISALIGNMENT Tilting values of the bearing rings may vary from 2 to 10 minutes of arc in regard to the radial clearance, and the size of the loads. We point out that during running the ring misalignment couses noise.

b) MINIMUM RADIAL LOAD That one can be calculated approximately with the formula: Fr min =0,01*Cr and there are taken steps to achieve it, when the force is not provided by the mass of the bearing components and of the external forces.

c) AXIAL LOAD For axial loads bigger than 0,25*Cor, please, ask for the specialists advise.

d) RUNNING TEMPERATURES Series made bearings can be used at temperatures of -30 through +110 0C. The special greases allow utilisations at temperatures of -50 through +120 0C.
