Load carrying ability

SONL plummer block housings are intended for loads acting vertically towards the base plate (support). In this case loads are limited only by the load limits of the bearing. If loads acting in other directions occur, check that the magnitude of the load is permissible for the housing, the bolts joining the housing cap and base, and for the attachment bolts.

Load carrying ability of the housing

Guideline values for the breaking load P of the housing for various load directions are provided in the table. The values apply to properly secured housings. Also see Mounting. Using these values and a safety factor selected with respect to the operating conditions, the permissible load for the housing can be calculated. In general engineering a safety factor of 6 is often used.

Load carrying ability of cap bolts

SONL plummer block housing cap bolts (bolts joining housing cap and base) of strength class 8.8 are standard. Guideline values for the maximum permissible radial load acting at various angles to the vertical can be found in the table.
