Deep groove ball bearings are the most common type of rolling bearings.The basic deep groove ball bearing consists of an outer ring, an inner ring, a set of steel balls and a set of cages. The deep groove ball bearing types are single row and double row. The deep groove ball structure is also divided into two types: sealed and open.

Spherical roller bearings have double row rollers, the outer ring has one shared spherical raceway, and the inner ring has two raceways that are inclined at an angle relative to the bearing axis. This ingenious construction makes it self-aligning and therefore not susceptible to axial or bearing housing angle errors or shaft bending. It is suitable for installation errors or shaft deflections that cause angular errors. In addition to being able to withstand

A needle bearing is a roller bearing with a cylindrical roller that is thin and long relative to its diameter. This type of roller is called a needle roller. Despite the small cross-section, the bearing still has a high load bearing capacity, and the needle bearing is equipped with a thin and long roller (roller diameter D ≤ 5 mm, L / D ≥ 2.5, L is the roller length), so The radial structure is compact, its inner diameter size

Single row angular contact ball bearings can only withstand axial loads in one direction and will cause additional axial forces when subjected to radial loads. And can only limit the axial displacement of the shaft or housing in one direction. Angular contact ball bearings have a contact angle of 40 degrees and can withstand large axial loads. Angular contact ball bearings are non-separable designs with different shoulder heights on the
