The difference between bearing and housing

[Summary]The slewing bearing seat is a large and extra-large bearing seat that can accept comprehensive loads and has a special structure. Bearing is an important part of contemporary machinery and equipment.

Information

1. Different in nature

The slewing bearing seat is a large and extra-large bearing seat that can accept comprehensive loads and has a special structure. Bearing is an important part of contemporary machinery and equipment.

2. Different functions

The bearing seat has the characteristics of compact structure, sensitive rotation, and easy maintenance of the device. Where there is a bearing, there must be a support point. The inner support point of the bearing is the shaft, and the outer support is often referred to as the bearing seat. The main function of the bearing is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy (accuracy).

Roller bearing

Roller bearing is a kind of rolling bearing, and it is one of the parts widely used in modern machinery. It relies on the rolling contact between the main components to support the rotating parts. Roller bearings are now mostly standardized. Roller bearings have the advantages of small starting torque, high rotation accuracy, and convenient selection.

Advantages and types of insulated bearings

Good insulation performance, using a special sealing method, J20AA coating can effectively insulate even in a humid environment, insulated bearings can be interchanged with standard bearings. For special occasions, such as outer ring rotation, bearings with J20C coating on the inner ring are recommended.

Analyze the different types of bearings and their uses

Rolling bearings are classified into radial bearings and thrust bearings according to the load direction they bear or the nominal contact angle. Radial contact bearings are radial bearings with a nominal contact angle of 0, and radial contact bearings are radial bearings with a nominal contact angle greater than 0 to 45. Bearings are an important part of modern machinery and equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. Bearing models generally consist of pre-code, basic code and post-code.

Bearing Knowledge" What is an axle box device? How to maintain it?

The axle box temperature is related to many factors, such as the load on the FAG bearing, operating speed, line status, air temperature, wind speed, continuous running time, quantity and status of lubricating grease, etc., all have a significant impact on the axle temperature. Two to three hours after the start of the vehicle, the bearing temperature tends to stabilize, and the heat generated by the friction of the bearing and the heat radiated from the outer surface of the axle box are close to balance. In the cold northern areas, the surface of the axle box dissipates heat quickly. The temperature difference between the top of the axle box and the inside of the bearing is as much as 30 to 40 degrees, while in the southern hot season, the temperature difference between the top of the axle box and the inside of the bearing is only about 100 degrees. Usually in summer, the temperature of the axle box on the side of the sun is much higher than the side of the back sun.
