SKF has launched complete solutions for bearing housings and accessories under the SIBCO brand, offering optimised performance solutions for a wide range of industrial applications.

Bearing housings are critical as they help to support the bearing, transmit the loads and also protect the bearing and lubricants from contamination. Bearing housings play a key role in maximising the performance and service life of the incorporated bearing.

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 dimensions of the SIBCO SNI plummer block housings conform to ISO 113 standard.

Product assortment includes: housings, seals, sleeves, lock nuts and lock washers.

Customer benefits: reduced unplanned downtime; reduced maintenance and warranty costs; increased efficiency and reliability; and easy serviceability

Highlights

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% fill of the free space between housing and bearing.

Better heat dissipation: There are additional ribs in the base at sides and centre, 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

Features: better machining quality – faster, easy and precise mounting; optimised running performance – allows higher speed, silent running and minimised vibration; and superior material quality – higher load carrying capacity and longer bearing service life.

Benefits: reduced downtime and maintenance costs; increased efficiency and reliability; reduced warranty costs; increased energy savings; and reduced total cost of ownership.

SIBCO accessories include: sleeves, locknuts and lock washers designed for longer life and easier maintenance.
