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
| Name Code | Characteristics | Using 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 |
Description
Deep groove ball bearing is a kind of the most common rolling
bearing. The basic type of deep groove ball bearing is composed of
an outer ring, a ring, a group of steel ball and a group of
retainers. Deep groove ball bearing has a single row and double row
two types, and also has sealed bearing and open bearing, open
refers to the bearing without sealing structure,sealing type deep
groove ball into the dust seal and oil seal. Dust seal cover
material for steel plate stamping, plays only a simple prevent dust
from entering the bearing raceway. Oil proof type contact type oil
seal, can effectively prevent bearing grease inside the spillover.
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.
