ZYSLThin-Wall Deep Groove Ball bearings

16000, 6700, 6800, 6900 series of thin-walled deep groove ball bearing is the most commonly used rolling bearing.Its structure is simple, easy to use.Is mainly used to bear radial load, but when increasing the bearing radial clearance, has certain properties of Angle contact ball bearing, joint can withstand diameter and axial load.In high speed and should not be using thrust ball bearing, could also be used to carry pure axial load.Compared with the same size of other types of bearings, such bearing small friction coefficient, high limit speed.But don't impact resistance, not suitable for carry heavy load.16000, 6700, 6800, 6900 series of thin-walled deep groove ball bearing is installed on the shaft, within the scope of the axial clearance of bearing, can limit shaft or the shell axial displacement in two directions, so can in two-way axial positioning.In addition, this class also has a certain bearing capacity, when compared with the shell hole '2 ~ 10', can still work normally, but had certain influence on bearing life.16000, 6700, 6800 more than 6900 series of thin-walled deep groove ball bearing cage for stamping steel ribbon cage, also can use engineering plastics, copper solid cage. Large bearing use car more metal solid cage.

The use of sealed bearing internal according to different environment can be added the corresponding special bearing grease.

Main structure form:

A. thin-walled deep groove ball bearing type 16000 6700 6800 6900;

B. periphery have locking groove of thin-walled deep groove ball bearing 6700 - N, 6800 - N, 6900 - N type;

C. a thin-walled deep groove ball bearings with dust cover 6700 - Z, 6800 - Z, 6900 - Z, two sides with a dust cover 6700-2 Z, 6800-2 Z, 6900-2 type Z;

D. a shield (contact), thin-walled deep groove ball bearing 6700 - RS 6800 - RS and 6900 - type RS, two sides contact seal 6000-2 - RS, 6200-2 - RS, 6300-2 type RS;

E. side with seals (non-contact) of thin-walled deep groove ball bearing 6700 - RZ, 6800 - in fact, 6900 - in fact, two sides of the non-contact deep groove ball bearing 6700-2 - rs, 6800-2 - rs and 6900-2 type rs;

16000, 6700, 6800, 6900 series of thin-walled deep groove ball bearings application: widely used in model aircraft, remote control cars, machine tools, motors, pumps, agricultural machinery, textile machinery, etc.

6700, 6800, 6900 series of thin-walled deep groove ball bearing has simple structure, convenient use, is the production batch of the largest and the most widely application scope bearing, mainly used to bear radial load.When bearing radial clearance increases with the performance of angular contact ball bearing, not bear the axial load increase.Such bearing small friction coefficient, vibration, low noise, high limit speed.Don't impact resistance, suitable for bear heavier load.According to the requirement of the user, can make advanced precision (P6, P5), various clearance categories, special vibration, noise requirements (Z1, Z2 or V1, V2) thin-walled deep groove ball bearings.
