Spherical roller bearing can bear heavy load, it has two row rollers, one common spherical raceway in outer ring, two raceway in the inner ring which inclined to a certain angle relative to the center line of axis, the bearing can be automatically self-aligning. when the bearing bent by the force or its installation of different mind,the bearing can still be normal use. Such bearing can withstand both radial load and bi-directional axial load, the fight ability is better.

Generally, spherical roller bearing permit the work of low speed.

Spherical Plain Bearings utilize inner & outer rings with spherical sliding surfaces, and can accommodate heavy radial loads &bi-directional axial loads at the same time. They are produced in a wide variety of designs & materials to satisfy diverse demands such as those in the automation, construction, mining, transportation,off-highway equipment, farming & machine tool applications. Standard designs utilize carbon chromium steel on steel which is hardened, phosphated and treated with Molybdenum Disulfide (MoS2) to reduce friction. Most designs can be relubricated through annular grooves & lubrication holes in the outer rings.
