Type MB: Traditional structural improvement design reinforced symmetrical rollers, with two brass alloy cages, and the inner ring has a middle rib. The design load is the same as the CC type, with the characteristics of high rated load and long service life.

Spherical roller bearings have double row rollers, the outer ring has a shared spherical raceway, and the inner ring has two raceways that are inclined at an angle relative to the bearing axis. Mainly bear radial load, but also can bear axial load in any direction. It has good impact resistance, and generally speaking, the allowable working speed of spherical roller bearings is low. It has the self-aligning performance that other bearings do not have, and the self-aligning performance varies with the bearing size series.

CC structure spherical roller bearings are characterized by the use of steel stamping cages, reinforced symmetrical rolling elements and movable spacers. Generally, it can be used in common with CA structure design.

The latest international design, it uses symmetrical spherical rollers, two-piece quenched steel stamped cages, the inner ring has no ribs and has a middle retaining ring guided by the cage.

Type E1 cage E is a reinforced type with higher load capacity. E1 is unique to X-LIFE and represents long life. The E1 type retainer is guided by an outer ring with a retaining ring in the middle, and in spherical rollers, it also represents an oil groove and oil hole.

The latest design adopts symmetrical spherical rollers, two-piece quenched steel stamped cages, and the inner ring has no ribs. Features: The cage used in EAE4 bearings has its own guiding function, which effectively reduces the friction caused by the guide ring and reduces noise on the basis of E-type bearings. The high speed and low noise brought by low torque are the biggest features of EAE4 bearings.
