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.
