A NEW generation of large size bearing housings being introduced to Australasia by Schaeffler is engineered to increase the life of fitted spherical roller bearings by up to 50 per cent, compared to conventional plummer block housings, Schaeffler said.

The FAG plummer block housing SNS is according to Schaeffler, designed to reduce the total cost of ownership of industrial machinery widely used in Australia and New Zealand, including machinery operating in aggressive environments.

Schaeffler Australia industrial sector and product manager Martin Grosvenor said the extended lifespan is made possible by the innovative housing design, which ensures optimum load distribution in the bearing.

The housing also provides a high sealing action against the ingress of contamination under extreme environmental conditions, making it suitable for use in aggressive environments commonly encountered in industry, the company said.

Different sealing variants allowing matching of the SNS to specific environments with particularly harsh contaminant and dust conditions.

An axial lubrication groove in the upper section of the housing ensures optimum lubricant supply for bearings in every bearing position, the company said.

The design also integrates good anti-corrosion characteristics and reduced cleaning requirements, due to inclined run-off areas as well as a projecting upper housing section.

These qualities, combined with increased strength and shock resistance due to the use of (EN-GJS-400) spheroidal graphite cast iron as standard, make the SNS particularly suited to applications in industries including mining and energy, oil and gas processing, materials handling, manufacturing and steel, and major infrastructure and water and wastewater plants.

“The focus during development of the new SNS plummer block housing was on compliance with customer and application-specific requirements,” Mr Grosvenor said.

“Criteria such as increasing efficiency, robustness and improved condition monitoring played a major role,” he added.
