Spherical Roller Thrust Bearings are a type of rolling element bearing designed to accommodate heavy axial loads in one direction while allowing limited radial loads. These bearings have raceways with a spherical shape, allowing them to self-align and compensate for misalignment between the shaft and the housing. They are specifically designed to handle axial or thrust loads, which forces are acting parallel to the shaft's axis and can withstand high axial loads and are commonly used in applications with heavy thrust loads. Spherical Roller Thrust Bearings may come with different cage materials, such as steel or brass, to retain and guide the rollers for smooth operation.
