SN220 Plummer block housing

Short Description:

SN series plummer block housings are split bearing housings for the fitting of self aligning bal or spherical roler bearings which are fixed to the shaft either by shrink fitting or with an adapter sleeve. They are designed for grease lubrication only andcan be supplied with lubrication holes if required.

SN Plummer Block Housings are designed for loads applied vertically to the bridging surface. In these instances the permissible load is determined by the load rating of fitted bearing. Should loads be applied at other angles, checks should be carried out to determine whether they are still valid for the housing, the housing connecting bolts and the mounting bolts.

housings from material GGG 40 & GS 45.Bolts to strength class 8.8 are supplied as standard for joining the housing upper and lower parts.

It is to be ensured that, when loading the housings, the connecting bolts and holding down bolts are tightened correctly.
