High Light water pump bearing ，power tool bearings

 

Features :

 

To bear predominate radial load and subsidiary  load from both directions, lower cost and price, low running resistance, high limiting speed, possible to reach higher rotating precision and pretty low vibration level, in addition, possible to make into sealing structure.

 

 

Applications :

 

Electric motors, machine tools, automobiles, precise devices, home appliances, chemical machineries, general machineries, agricultural machineries, etc

 

 

Deep groove ball bearing Advantages:

 

1) High precision, long life , Low noise,low vibration

 

2) Easy for installation and unloading


3) Fast delivery,good quality


4) Competitive price

 

 The size of bearing clearance directly related to the use of noise, vibration, normal temperature, service life and the assembly of machinery motion effect. Therefore, it is very important that we choose the suitable assembly bearing clearance. We divided from small to big according to radial clearance range into C2, C0, C3, C4 and C5. Specific reference see the chart:

 Also can consult the table below choose bearing clearance

 

The usage situation Use examples Choose clearance
Strict control noise, vibration installation precision, high position Instrument and equipmentRoll neck calender Low noise and small motor C2,C0
General load, speed, working temperature is not high Transmission machinery, reducer and other general machinery C0
High temperature, high speed, high requirements for service life Automobile generator and engine C3
Using high temperature environment, should not be the occasion of heat Drying machine, paper making machinery, and so on C3,C4
High temperature, high speed, and large impact load

Vibrating screen, speed gear

Bearing vibration and noise level can be divided into 4 levels: Z1, Z2, Z3 and Z4. We can detect by S0910-1 instrument. According to the special requirement, we can use BVT-1 detection, and be divided into the V1, V2, V3 and V4.Specific data are listed below. Customer’s order should be indicated the vibration and nosie level requirements.

 

The maximum vibration acceleration of single bearing. Tolerance dB
