Split plummer block housings SNL 30, 31 and 32 series


             Load carrying capacity of the cap bolts
             Approximate values for the yield points for cap
             bolts are provided in table 7. The values in
             table 7 apply to 8.8 strength cap bolts, which
             are supplied with SNL and SNLD housings.
               If a safety factor of 6 is used for the permis-
             sible load of grey cast iron SNL housings, the
             cap bolts do not need to be considered. In this
             case, the permissible load of the housing is
             less than the permissible load for the cap
             bolts.
                                                                             Table 7
