Optimised performance solutions for a wide range of industrial applications
SIBCO is an SKF Group brand and the offerings as a part of SIBCO cover a wide range of industrial applications. SIBCO solutions deliver the same superior quality and performance that one associates with the SKF brand.
SIBCO SNI Housings
Optimised 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 provides different options for the selection of bearings and methods of mounting. 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 standard.
Sleeves, locknuts and lock washers designed for longer life and easier maintenance SKF through its SIBCO brand offers high quality sleeves which ensure optimal bearing performance. Adapter sleeve is the most commonly used component for locating bearings with tapered bore onto a cylindrical seat, as they can be used on a plain or stepped shaft. Adapter sleeves are easy to install and require no additional location on the shaft. All standard SIBCO adapter sleeves are made of 0.20% - 0.30% carbon steel. However, larger sleeves and sleeves of special types are made of 0.30% - 0.45% carbon steel.
The dimension of the metric adapter and withdrawal sleeves conform to ISO 2982-1 standard. Withdrawal sleeves are also available on request as part of the SIBCO range.
Stiffer and robust housing
The engineered and optimised design of SIBCO SNI plummer block housings, together with 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
To avoid over-filling, markings at each corner inside the housing base indicate the proper grease level for an initial 20 or 40 per cent fill of the free space between housing and bearing.
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 lock 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 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 better traceability.
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.
