Deep groove ball bearing
Deep groove ball bearing is the most common type of rolling bearings. The basic type of deep groove ball bearing consists of an outer ring, an inner ring, a steel ball and a group of cage. There are two kinds of single and double row deep groove ball bearing, deep groove ball structure also sealed and open two open structure. Refers to the bearings without sealing structure, sealing type deep groove ball into dust seal and oil seal
Inside diameter range
10mm～1320mm
Outside diameter range
30mm～1600mm
Width size range
9mm～300 mm
Bearing characteristic
Deep groove ball bearings are the most representative, widely applicable to high speed. Even high speed operation, and very durable, does not need regular maintenance. This kind of bearing friction coefficient is small, extreme high speed, simple structure, low manufacturing cost, easy to reach high manufacturing precision. Different size and forms, used in precision instruments, low noise motor, automobile, motorcycle and general machinery and other industries, is the most widely used type of bearings in machinery industry. The main radial load, axial load can bear a certain amount.
Select bigger radial clearance axial bearing capacity increased under pure radial force when the contact angle is zero. Under the action of axial force, contact angle is greater than zero. The general use of the stamping wave shape keep frame, car solid cage, sometimes using nylon frame.
Deep groove ball bearings installed in the shaft, in bearing axial clearance range, axial displacement can limit shaft or shell in two directions, so it can be two-way axial orientation. In addition, this kind of bearing has certain self-aligning capability, when compared to the shell hole inclination of 2 '~ 10', still can the normal work, but has a certain effect on the bearing life. Deep groove ball bearing retainer more for stamping steel ribbon cage, large bearing of the metal entity keep a car.
Deep groove ball bearings are most commonly used. It has the advantages of simple structure and convenient use. Mainly used to bear radial load, but with the increase of bearing radial clearance, the performance has a certain angle contact ball bearing, can bear radial, axial joint load. At high speed and not using thrust ball bearings, can also be used to withstand pure axial load. Compared with other types of bearings with the same size deep groove ball bearings, the bearing friction coefficient is small, high speed limit. But don't impact resistance, not suitable for under heavy load
Application use
Deep groove ball bearings can be used for transmission, instrumentation, motors, household appliances, internal combustion engines, traffic vehicles, agricultural machinery, construction machinery, construction machinery, roller skates, yo yo, etc.
