Spherical roller bearings have double row rollers, the outer ring has a common spherical raceway, the inner ring has two raceways and is inclined at an angle relative to the bearing axis. This ingenious structure makes it have automatic centering performance, so it is not easy to be affected by the angle of the shaft and the bearing box seat or the bending of the shaft. It is suitable for the installation error or the deflection of the shaft. The bearing can not only bear radial load, but also can bear two-way axial load.

Thrust ball bearings are designed to withstand thrust loads during high-speed operation and are composed of washer-like ferrules with ball rolling raceway grooves. Since the ring is cushion-shaped, thrust ball bearings are divided into two types: flat-bottom seat cushion type and self-aligning spherical seat cushion type. In addition, this bearing can bear axial load, but not radial load.

The single-row cross-roller slewing bearing is composed of two seat rings. It has compact structure, light weight, high manufacturing accuracy, small assembly gap, and high installation accuracy. The rollers are arranged in a 1:1 cross and can bear at the same time. Axial force, tilting moment and large radial force are widely used in lifting and transportation, engineering machinery and military products.

Linear guide can be divided into roller linear guide, cylindrical linear guide, ball linear guide three. They are used to support and guide the moving parts in a given direction of reciprocating linear motion. According to the different friction characteristics, linear motion guides can be divided into sliding friction guides, rolling friction guides, elastic friction guides, fluid friction guides, etc.

The cone angle of the outer ring raceway of the single row tapered roller bearing is between 10 ° and 19 °, which can bear the combined action of axial load and radial load at the same time. The larger the cone angle, the greater the ability to withstand axial loads. Large cone angle bearing, rear code plus B, cone angle between 25 ° ~ 29 °, it can withstand large axial load. In addition, single row tapered roller bearings can adjust the size of the clearance during installation. The outer ring (or inner ring) of the double row tapered roller bearing is a whole. The small end faces of the two inner rings (or outer rings) are similar, and there is a spacer in the middle. The clearance is adjusted by the thickness of the spacer, and the thickness of the spacer can also be used to adjust the pre-interference of the double row tapered roller bearing.

Cylindrical rollers and raceways are line contact bearings. Large load capacity, mainly to bear radial load. The friction between the rolling body and the retaining edge of the ferrule is small, and it is suitable for high-speed rotation. According to the ring with or without ribs, it can be divided into NU, NJ, NUP, N, NF and other single-row cylindrical roller bearings, and NNU, NN and other double-row cylindrical roller bearings. The bearing is a structure in which the inner ring and the outer ring can be separated. The inner ring or outer ring of cylindrical roller bearings without rib, the inner ring and outer ring can make relative movement to the axial direction, so it can be used as a free end bearing. A cylindrical roller bearing with a double rib on one side of the inner ring and the outer ring, and a single rib on the other side of the ring, can withstand a certain degree of axial load in one direction. The cage is made of three different materials: polyamide (ECP), steel (ECJ), brass (ECM).
