Double The Running Life

BMG’s NSK HPS range has a running life nearly double that of conventional bearings of the same size, ensuring reduced maintenance costs, substantial energy savings and downsizing in product design. 

The maximum limiting running speed of these spherical roller bearings has also improved by 20%.

“During rotation of conventional spherical roller bearings, slip between the raceway and roller causes fatigue, which eventually leads to flaking. To counter this, NSK has developed a special treatment on the surface of the outer ring that improves the traction of rollers and controls the rotational speed of these rollers,” says Wayne Holton, Business Unit Manager, Bearings, Seals and Gaskets division, BMG. 

“This advanced technology, which has extended the service life of these bearings by up to twice that of conventional spherical roller bearings, also increases the bearings’ dynamic load rating.”

In addition, NSK applies a special nitriding treatment on the surface of the cage which forms a finer, harder and more uniform surface than on conventional bearings. Maximum limiting speed is significantly increased and cage wear in harsh operational applications is reduced.

Robust HPS spherical roller bearings, which are available nationally from BMG, have bore sizes from 40mm to 130mm. These bearings offer extended service life, reduced maintenance and enhanced performance in heavy-duty applications.

BMG’s specialist divisions have advanced technical skills to support the company’s commitment to applying technical knowledge and depth of experience to maximise efficiency and profitability for every customer.

The company has secured distribution and service agreements with some of the world’s most respected manufacturers of bearings, including NSK, NTN, Timken, IKO and Rollix.
