Load capacity Grey cast iron ball bearing units SNR Ball Bearing Units SNR Industry 12 SNR housings permit the complete utilization of the bearing insert load rating. The specified radial dynamic load rating of the inserts can be presumed as the maximum radial load capacity of the unit. For the housings of the T200 and T300 series the radial dynamic load rating must be multiplied by a factor of 0.3. The maximum axial load capacity of the inserts is 0.5 x C 0r (radial static load rating). The following safety factors must be taken into consideration for various types of stress: Type of stress Safety factor Constant load 1 Dynamic load 1 – 1.5 Moderate shock load 2 High shock load > 3
