Bearing is an important component in textile machinery and equipment. It is mainly used to support mechanical rotating bodies and reduce the coefficient of friction during their movement. According to the different friction properties of moving elements, bearings can be divided into two categories: rolling bearings and sliding bearings. Among them, rolling bearings have been standardized and serialized, but compared with sliding bearings, their radial size, vibration and noise are larger, and their prices are higher.

1. Deep groove ball bearings

Deep groove ball bearings are the most representative rolling bearings, which can withstand radial and axial loads in a wide range of applications, and are suitable for high-speed rotary machines that require low noise and low vibration. Deep groove ball bearings with stopper rings or flanges in the outer ring are easy to position axially and easy to install in the housing, mainly used for rear wheels, transmissions, and electrical device parts of automobiles.

2. Four-point contact ball bearing

Four-point contact ball bearings can withstand radial and bidirectional axial loads, and a single bearing can replace angular contact ball bearings with a frontal or rear combination, and are suitable for bearing pure axial loads or combined loads with a large axial load component. These bearings are subjected to axial loads in any direction to form one of the contact angles (α), so that the ring and the ball are always in contact with each other on either contact line. It is mainly used for aircraft jet engines and gas turbine parts.

Textile machine bearing is an indispensable part of textile machinery, although the shape of the bearing is small, but its role can not be ignored. In actual operation, it is necessary to pay attention to the regular maintenance and maintenance of bearings.
