Bearing handles demanding applications
Bower Type E designed for use in heavy industries.
There’s a new bearing in town. The Bower Type E from NTN Bearing Corp. of Canada Ltd. (based in Mississauga, Ont.) is designed to meet demanding applications in heavy industries such as aggregate, wood processing, mining, cement, steel, water treatment and construction.
The one-piece sturdy cast iron housing with elongated mounting slots holds a spherical roller bearing insert that allows for +/- 2 degrees of misalignment. It has a set screw locking collar, machined brass retainer, double-lip heavy contact seal with metal shield, and an extended inner ring. Sizes range from 1 7⁄16 to 4 15⁄16 pillow blocks with either 2-bolt or 4-bolt configurations and it’s a direct drop-in interchange with other Type E pillow block units.
Since the spring of 2018, NTN has conducted 11 onsite trials of the bearing and they have run without issues at each location for 16-plus months, a minimum of 2.5 times longer service life than the bearings that were replaced.
