Description


Radial Clearance: Cm,C0 and C3 can be produced

Noise Class:Z3V3,Z4V4 class

Dimension Tolerance: ABEC-3 class

Packing: Industrial tube packing or customized packing.

Applications :

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

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

 C4
Inner and outer ring take the surplus interference, large volume, high temperature, heat dissipation Vibration type pressure road, machine car rear wheel C5

Bearing material

Outer ring, inner ring, ball:

High-carbon chromium bearing steel Gcr15(JIS SUJ2,AISI 521000), or stainless steel 9Cr18(AISI 440C)

Cages:

Steel plates and nylon can be used in general situation, while rubber and stainless steel for special usage.

Cover:

Steel plate for shield, and rubber for seals

Rings and balls vacuum dealing with treatment of high carbon chromium bearing steel GCR15 is the standard material to produce the accurate internal and external circle and ball. This material is same with the USA AISL 52100, Germany DIN 100Cr6, Japan JISSUJ2.

The standard cage is made of carbon steel by cold, but in-corrosive environment, no parallel, or under high-speed operation, we can use stainless steel, nylon or phenolic resin cage according to customer’s request.
