RADIAL TYPE SPHERICAL PLAIN BEARINGS

STANDARD SERIES

-EL and MB-E SERIES

BH-L and MBH- SERIES

Y //A

OPEN

SEALED

Designed to support heavy radial loads under

misalignment. These bearings also possess moderate thrust loading capability. They are non-separable with a single fractured outer ring, and are available in open or sealed designs and inch or metric sizes.

Due to greater inner ring cross section, the BH-L and MBH series is capable of greater misalignment. Available in open or sealed designs and inch or metric sizes.

With an extended inner ring, the need for additional locational spacers is eliminated. The inner ring bore is relieved to prevent excess bending stress. Available in open or sealed designs and inch or metric sizes.
