Spherical roller thrust bearings have specially designed raceways and asymmetrical rollers. The bearings can accommodate axial loads acting in one direction and simultaneously acting radial loads. The load is transmitted between the raceways via the rollers at an angle to the bearing axis, while the flange guides the rollers.
spherical roller thrust bearings are separable, making it possible to mount and dismount the housing washer separately from the shaft washer and roller and cage assembly. In addition this facilitates maintenance inspections.Spherical roller thrust bearings achieve high thrust capacity with low friction and continuous roller alignment – even if the shaft and housing become misaligned during operation.Timken designed type TSR thrust spherical roller bearings to achieve a high thrust capacity with low friction and continuous roller alignment. This bearing type is ideal for operating conditions that experience heavy loads, difficulty in establishing or maintaining housing alignment, or shaft deflection.Spherically contoured rollers, arranged in a steep angular position, accommodate high thrust loads and support moderate radial loads.Bearing geometry and manufacturing technology result in low friction of bearing.Internal self-alignment of bearing elements during operation compensates for shaft deflections and housing distortions caused by shock or heavy loads.The TSR’s inherent compensation for misalignment offers equipment designers the opportunity to use weldments for housing frames instead of complex castings, which reduces machining costs.
