Types Of Motorcycle Bearing

Bearing is an important part of contemporary machinery. Its main function is to support the mechanical rotating body, reduce the friction coefficient in the process of movement, and ensure its rotation accuracy. This paper will introduce the types of OEM motorcycle bearings.

Types Of Motorcycle Bearing

According to the different friction properties of moving elements, bearings can be divided into rolling bearings and sliding bearings.

Deep groove ball bearings, cylindrical roller bearings and thrust ball bearings are commonly used in rolling bearings. Among them, the rolling bearing has been standardized and serialized, which is generally composed of four parts: outer ring, inner ring, rolling element and cage.

Deep groove ball bearing

Deep groove ball bearings mainly bear radial load, and can also bear radial load and axial load at the same time. When it only bears radial load, the contact angle is zero. When the deep groove ball bearing has large radial clearance, it has the performance of angular contact bearing and can bear large axial load. The friction coefficient of deep groove ball bearing is very small and the limit speed is also very high.

Deep groove ball bearing is the most representative rolling bearing with a wide range of applications. It is suitable for high speed or even extremely high speed operation, and it is very durable without regular maintenance. This kind of bearing has the advantages of small friction coefficient, high limit speed, simple structure, low manufacturing cost and high manufacturing accuracy. The size range and forms vary widely. It is used in precision instruments, low-noise motors, automobiles, motorcycles and general machinery industries. It is the most widely used type of bearing in the machinery industry. It mainly bears radial load and a certain amount of axial load.

Cylindrical roller bearing

Cylindrical roller bearing, the rolling element is the centripetal rolling bearing of cylindrical roller. The cylindrical roller and raceway are linear contact bearings. Large load capacity, mainly bearing radial load. The friction between the rolling element and the retaining edge of the ferrule is small, which is suitable for high-speed rotation. According to whether the ferrule has retaining edge or not, it can be divided into single row bearings such as Nu, NJ, NUP, N and NF, and double row bearings such as NNU and NN.

Cylindrical roller bearing with inner ring or outer ring without retaining edge, whose inner ring and outer ring can move relatively axially, can be used as free end bearing. A cylindrical roller bearing with double retaining edges on one side of the inner ring and the outer ring and a single retaining edge on the other side can bear a certain degree of axial load in one direction. Generally, steel plate stamping cage or solid cage made of copper alloy are used. However, some use polyamide shaped cages.

Thrust ball bearing

The thrust ball bearing adopts the design that can bear the thrust load during high-speed operation, and is composed of washer like ferrule with ball rolling raceway groove. Because the ferrule is cushion shaped, the thrust ball bearing is divided into two types: flat bottom cushion type and self-aligning spherical cushion type. In addition, the bearing can bear axial load, but can not bear radial load.

The thrust ball bearing is composed of race, shaft ring and steel ball cage assembly. The shaft ring matched with the shaft and the seat ring matched with the housing. The thrust ball bearing is only applicable to the parts bearing one side of axial load and low speed, such as crane hook, vertical water pump, vertical centrifuge, Jack, low-speed reducer, etc. The shaft ring, seat ring and rolling element of the bearing are separated and can be installed and disassembled separately.
