Basic deep groove ball bearings of different sizes are made up of one inner ring, one outer ring, one cage and a group of balls. It can bear both radial and axial load capacity. Therefore, it can also be divided into axial deep groove ball bearing and radial deep groove ball bearing. More+
Spherical Roller Bearings Spherical roller bearings are self-aligning and have 2-row rollers, a common spherical outer-ring raceway and 2 inner-ring raceways. The geometry of spherical roller accommodate the bearings to bear huge radial loads and resist the impact forces and dynamic loads. The bearings are active to misalignment of the shaft relative to the housing. Take it for example, the misalignment is caused by the deflection. The feature of spherical roller bearings is its special ability for bearing both radial and axial heavy loads. Spherical roller bearings usually undergoes more frictional losses and work at relative lower speeds. More+
Single Row Spherical Roller Bearing Single-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. More+
Single Row Cylindrical Roller Bearing Single row cylindrical roller bearings with cages are part of radial roller bearings. Compared with the ball bearings’ balls, the rollers have a bigger contact to the roller axle. More+
