SNH housing

World-class quality housings for demanding applications

SKF offers a range of small to large size split plummer block housings primarily designed for self-aligning ball bearings and spherical roller bearings mounted directly on cylindrical shafts or on adapter sleeves. The design of the housings provides different options for the selection of bearings and methods of mounting.

Design features

Grease level marking
Grease level making
To avoid over-filling, markings at each corner inside the housing base indicate the proper grease level for an initial 20% or 40% fill of the free space between the housing and bearing.
Better heat dissipation
Better heat dissipation
There are additional ribs in the base at sides and center which increases the contact area between base and the support surface. This reduces operating temperatures and increases the service life of the bearings, seals and lubricant.
Dimples to locate accessories and improved lubrication facilities

Dimples cast into the housing cap indicate where grease fittings and condition monitoring sensors can be mounted for maximum effectiveness.
Improved markings on the housings
Improved markings on the housings
The housing cap and base are matched during manufacturing and are not interchangeable with the caps and bases of other housings. The serial number on both housing parts is more readable to help avoid any mismatches. The designation on the housing cap has also been enhanced for readability and now contains the complete housing designation for better traceability.
Easy & Reliable mounting
To simplify mounting and make alignment more accurate, lines indicating the center of the bearing seat and housing bore axis, are cast into the housing base. Dimples indicate the position for dowel pins.
