Bearing Man Group (BMG) (www.bmgworld.net) announced that it has expanded its product offering to include a new series of housed bearing units.

“These imperial housed tapered roller bearing units were the missing segment from BMG’s housed bearing product portfolio. The addition of this product range by one of our key supply partners enables BMG to better satisfy customer demand,” said Rouff Essop, Bearings Division Manager at BMG.

Designed for extended service life and efficient performance in demanding environments, the QMSN series is developed with cast steel housing that offers three times the cast-iron housing’s tensile strength. The robustness of the spherical roller housed unit allows the bearing to be replaced several times.

These units are ideal for use in aggregates and mining operations, including in automotive, oil and gas, steel, agriculture and power generation industries. The new series is also suitable for use in saw mills, treatment facilities, pulp and paper industry as well as in food and beverage industry.

The QMSN series offers three standard sealing options — the triple lip Viton rubber series, Teflon labyrinth seals and the triple lip nitrile rubber series.

Aside from the units’ standard locking method, they also feature eccentric collar. Unlike the ball bearing housed units’ eccentric collar, the QMSN’s collar comes with a shallow ramp when it is rotated to the inner ring. Moreover, the axial contact area’s angle between the inner ring and the collar is bigger than normal, effectively preventing the locking mechanism from loosening.

The series alternative locking methods include a tapered sleeve lock with a standard adaptor sleeve arrangement, a grub screw lock and the new V-lock, which encompasses a double taper locking method.
