SCHAEFFLER PLUMMER BLOCK TECHNOLOGY EXTENDS 50% BEARING LIFE BY Plummer block housings launched by Schaeffler Australia responds to industry demands of material processing, manufacturing and more. 34 April 2017 M A T E R I A L S The new generation of FAG plummer block housings are large-size bearing housings, engineered to increase the service life of fitted spherical roller bearings by up to 50% compared to conventional plummer block housings. Their advances – including increased strength and shock resistance due to the use of (EN-GJS-400) spheroidal graphite cast iron as standard – make the SNS ideal for the broad diversity of applications where spherical roller bearings are widely used, including machinery operating in aggressive environments, says Schaeffler Australia Pty Ltd industrial heavy industries manager, Jeff Gordon. Key applications include industries such as mining and minerals processing, quarrying, cement, manufacturing, oil and gas processing, bulk materials handling (including port loading facilities), manufacturing and steel, primary product and food and beverage processing, pulp, paper, packaging and forestry, and major infrastructure and water and waste water plants. The new plummer blocks – for shafts from 115mm to 530mm and from 4 7/16 inch to 19 1/2 inch diameter – are one of the latest global technology advances from the Schaeffler Group, which employs more than 80,000 people worldwide. Schaeffler’s research and development centres alone employ more than 6,000 people dedicated to high-performance, lowmaintenance bearing technology that enhances sustainability by maximising machinery life and minimising energy demands. Such low-maintenance technologies are ideal for all industries that can’t afford breakdowns or production stoppages, Mr Gordon told the Perth launch, held after the arrival of stocks of the first of the new technology bearings in Australia and New Zealand. The unique, patented design of the FAG SNS plummer block housing distributes the load on the bearings more effectively (uniformly) than previous and alternative housings. Using its in-house developed bearing design, calculation and simulation software, Bearinx, Schaeffler is able to analyse different housing designs with various combinations of bearings, enabling the optimisation of the complete system (housing and bearings). The FAG SNS housing design is a split plummer block, which allows maintenance to be carried out more efficiently and quickly by providing easier access to the bearing, which saves time and money. Additionally, Schaeffler can provide a special split The SNS housing design distributes loads more evenly in the rolling bearing, extending the operating life of the bearing (left), while mounting, lubrication and condition monitoring are made much easier by numerous details of the new housing design. labyrinth seal which facilitates the use of the FAG split spherical roller bearing inside the housing. FAG split spherical roller bearings radically simplify cutting, mounting and maintenance downtime by 50% or more while reducing costs by eliminating complicated bearing replacement procedures in machinery and plant. Four different seal variants including high speed labyrinth seals, split labyrinth, clip-in and bolt-on Taconite seals ensure effective sealing of the FAG plummer block housing SNS radically increases bearing life while making lubrication, mounting, and condition monitoring much easier than conventional types.
