High Rotation Speed Water Pump Ball Bearing , Machine Tool Bearings Single / Double Row

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.

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.

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:
