Bearings are an indispensable and essential component in contemporary mechanical equipment. Its primary function is to support the mechanical rotating body, reduce its friction during movement, and ensure its turning accuracy. It plays an important role in extending the life of the machine. Plane bearings and thrust bearings are components composed of a flat cage assembly with a needle roller or a cylindrical roller or a steel ball and a flat washer. Thrust ball bearings is designed to withstand thrust loads at high speeds and consist of washer-like rings with ball rolling grooves.

Thrust ball bearings:

According to the force situation, it is divided into one-way thrust ball bearings and two-way thrust ball bearings. One-way thrust ball bearings can withstand unidirectional axial loads. Two-way thrust ball bearings can withstand two-way axial loads, of which the collar and the shaft cooperate. The bearing with a spherical mounting surface has a self-aligning performance, which can reduce the impact of mounting errors. Thrust ball bearings cannot bear radial loads, and the limiting speed is low.

Thrust ball bearing features:

1. There are two types of unidirectional, bidirectional;

2. To allow installation errors, whether it is unidirectional or bidirectional, you also can choose spherical self-aligning spherical seat cushion types or spherical seat type;

3. High-quality steel ―Using ultra-clean steel that can extend the bearing life up to 80%;

4. High-level grease technology ― NSK's lubricant technology can extend the life of grease and improve bearing performance;

5. High-quality steel ball quiet and smooth when rotating at higher speed;

6. Using the ferrule in the option to allow installation errors.

Wuxi Spark Bearing Co., Ltd is a professional manufacturer of plain bearings, thrust bearings, plane thrust bearings, thrust ball bearings, non-standard bearings, automotive clutch bearings, thrust roller bearings, inch Manufacturers of thrust bearings, non-standard housing bearings, housing bearings, non-standard bearings, pressure bearings, eight types of bearings, 52 series bearings, 29 series bearings, thrust bearings and other non-standard bearings for automobiles.

The higher rigidity of the bearing housing, the total sound pressure level of the raceway sound. If the radial clearance is minimal, the overall sound pressure level and dominant frequency of the track sound will increase sharply as the radial clearance decreases. The methods for controlling the sound of the raceway include: selecting low-noise bearings, that is, bearings with low waviness, and carefully selecting the conditions of use. 

The music of the raceway often affects the noise of the entire machine. Reducing the sound of the raceway can reduce the noise of the whole engine — year rising trend.

Thrust ball bearings are widely used in some machinery and equipment, such as elevator parts we often ride on, as well as some plastic machinery and office equipment. It will also be used in medical equipment, stepper motors, reduction gears, pressure rotors, fitness, and sports equipment. 

As a specific example, when a car needs to turn, this is when the plane bearing is functioning. If the plain bearing of the shock absorber is broken, there will be abnormal noises in the first turning direction because the function of the automobile shock absorber plane bearing is to act as a link between shock absorption and the body of the vehicle, avoiding direct friction. 

If it is broken, there will be a rattling noise, whether it is in the direction of the place or in the general direction of driving. At the same time, there is also a sense of vibration, and the course will sink.
