For heavy loads, harsh working conditions or special requirements for sealing, built-in contact type sealed spherical roller bearings can be used.

The outer dimension of the bearing is exactly the same as that of the non-sealed bearing, which can replace the non-sealed bearing in many occasions.

The allowable alignment angle is 0.5°, and the working temperature is -20~110. The bearing has been filled with an appropriate amount of lithium-based anti-rust grease, and grease can also be added according to user requirements. According to whether the inner ring has ribs and the cage used, it can be divided into two basic types: C type and CA type. The characteristics of C type bearings are that the inner ring has no ribs and the steel plate stamping cage is used. The characteristics of CA type bearings There are ribs on both sides of the inner ring and a car-made solid cage is adopted. This type of bearing is especially suitable for working under heavy load or vibration load.

Spherical roller bearings are equipped with drum-shaped roller bearings between the inner ring with two raceways and the outer ring with spherical raceways.
