BMG’s NSK HPS spherical roller bearings for demanding environments 2021

BMG’s range of high-performance NSK spherical roller bearings is perfectly suited to operate in demanding environments, including foundries, forges and die-casting applications.

The NSK HPS range, which has a running life nearly double that of conventional bearings of the same size, also ensures 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 bearinsgs’ dynamic load rating.”

NSK also 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.

BMG’s extensive bearings portfolio is carefully selected in terms of consistent quality controls, compatibility, standardisation, reliability and extended service life. The BMG team is committed to working closely with customers in all industries to investigate the source of bearing problems and to provide cost-efficient solutions for optimum productivity of machinery, extended service life of the system, and minimal maintenance requirements.
