    Good Reliability ABEC-3 Washing Machine Bearings Steel Cages ISO Approved

    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.


    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:
