Spherical Roller Bearings
Spherical roller bearings are designed to adapt to severe misalignment caused by mounting or deflection on the shaft & housing. Not every type of bearing has the ability to face the challenge of misalignment. Meanwhile, due to its two row of rollers, spherical roller bearings are able to bear high radial loads and some axial loads. They adopt a spherical or crowned rollers as rolling elements and raceway of the outer ring is also in spherical shape. For shock loads, their feature of self-aligning helps to absorb but has limited capabilities to high speed. As one of the widely used bearings, spherical roller bearings do you a favor in obtaining lower maintenance cost, increasing the productivity and prolong the service life.
Different Types of Spherical Roller Bearings
-
Single Row Spherical Roller BearingSingle-row spherical roller bearings are self-retaining and they can handle both radial and thrust loads. Bar contact is another feature of single-row spherical roller bearings. -
Double Row Spherical Roller BearingDouble-row spherical roller bearings have spherical raceways in the outer rings of two rows of rollers. They can handle large radial loads and are able to bear axial load in any direction. -
Thrust Spherical Roller BearingsSpherical thrust roller bearings is a kind of thrust rolling bearing. They allow low friction rotation and angular deviation and are designed to bear radial load and one-way axial load.
