Deep groove ball bearings are particularly versatile.They are suitable for high and very high speeds, accommodate radial and axial loads in both directions and require little maintenance. Because deep groove ball bearings are the most widely used bearing type, they are available from VCD in many designs, variants and sizes.


VCD produced 608 deep groove ball bearings(Z3V3 class) are widely used in different types of air conditioners.Now we have established supplying relations with many air conditioners producers in China and

1. 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.


Applications:

Deep groove ball bearing can be used for transmission, instruments and meters, electric machinery, household electrical appliances, internal combustion engines, transportation vehicles, agricultural machinery, construction machinery, engineering machinery, roller skate,yo-yo etc.


2. Bearing Seal

Bearing seal form into dust cover and plastic material seal. There are various types of seal. Because of different seal material, bearing to adapt condition will also change.

Name CodeCharacteristicsUsing Temperature

NBR

Acrylonitrile-butadiene rubber

Oil resistance,heat resistance,resistance to wear-40~120

FKM

Fluorine rubber

Hear resistant,acid and alkali resistant and chemicals, oil resistance preferred-20~200

VMQ

Silicone rubber

Heat and cold resistance, good compression deformation is small, but the mechanical strength is not good-60~230

ACM

Polypropylene acid ester rubber

Heat resistance, oil resistance better than NBR, but resistance to water and alkali is not strong-20~150

3. 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:

5. Bearing can choose diversity of greases. According to the different work environment and bearing operation conditions, we used the following list of grease, in order to convenience for clients to choose. Besides these greases of the listed below, can also add other greases according to the requirements of our customers.
