SIBCO SNI Housings

Optimized solutions designed for maximum reliability and minimal maintenance

SIBCO SNI housings are 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 SIBCO housings provide different options for the selection of bearings and methods of mounting. The SIBCO SNI housings are suitable for grease lubrication and use grade 10.9 cap bolts. All standard SIBCO SNI housings are made of grey cast iron. However, SKF also manufactures a range of SIBCO housings of SNI design in spheroidal graphite cast iron and cast steel. The dimension of the SIBCO SNI plummer block housings conform to ISO 113 standards.

Design features

Stiffer and robust housing
Stiffer and robust housing
The engineered and optimized design of SIBCO SNI plummer block housings,together with their improved material grade,make them more robust compared to other housings in the market. With additional ribs in the base, SIBCO housings are stiffer.
Grease level marking
Greaves level marking
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 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 inter-changeable 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.
Simple mounting and dismounting
Simple mounting and dismounting
To simplify mounting and make alignment more accurate, lines indicating the centre of the bearing seat and housing bore axis are cast into the housing base. Dimples indicate the position for dowel pins
