Spherical roller bearings are double row, combination radial and thrust bearings that can self-align. The element material used is a spherical or crowned roller.
The outer ring has a spherical race misalignment of the shaft and housing. The symmetrical barrel rollers freely align themselves with the concave annulus. Therefore, the deformation of the shaft and misalignment of bearing seats are compensated. Spherical roller bearings have a super high load capacity and tolerance to shock, while its speed capabilities are limited. By some estimates, spherical roller bearings have almost double the life of conventional bearings.
Bearing usually made of stainless steel or low carbon steel. In some cases, chromium-bearing is also available. Some applications require a thorough case-hardened and tempered high carbon steel, where steel. grades of high carbon steel do not require fuel mixture. A low, quality hardened steel, carbon introduced after bearing machined to a depth sufficient to produce hardened able to maintain the load.
