30*62*24 B30-39GC4 NSK ball type Axle Shaft automotive alternator bearing

Introduction of 30*62*24 B30-39GC4 NSK ball type Axle Shaft automotive alternator bearing :

30*62*24 B30-39GC4 NSK ball type Axle Shaft automotive alternator bearing general with structure of the general sealed deep groove ball bearings, the code method and dimensions in line with current standards require a good sealing performance and high-speed performance, using the base grease, grease filling space accounted for bearings 20% -30% of the internal space, bearing parts of the heat treatment should ensure that the bearing temperature of 150 ℃ in the normal work.Motor bearing is  a kind of specail bearing whichi is specially applied to the motor. Motor bearing is a supporting shaft part. It can guide the axis of rotation, can also turn over the shaft parts, under the concept of bearing is very broad. There are four commonly used types of motor bearing: the rolling bearing, sliding bearing, joint bearing and oil bearing. The most common motor bearing is rolling bearing, namely have a rolling element bearing. Sliding bearing has no rolling element bearings, it means the bearing only can make sliding movement. There are also some bearings for a Boundary Lubricants.

Features of 30*62*24 B30-39GC4 NSK ball type Axle Shaft automotive alternator bearing :

1)In the structure, each ring of deep groove ball bearing has continuous raceway groove which the

cross section is about a third of the ball girth.

2) When the radial clearance of bearing increases, it will have the properties of angle contact ball bearing,

and it can bear alternating axial load in two directions.

2) Small friction, high speed.

3)Simple structure, low manufacture cost, easy to achieve high manufacture precision.

4)Deep groove ball bearing has as many as 60 variant structures.
