Features | 1.High quality and good service 2.Less friction and low noise 3.Competitive price 4.Quick delivery 5. Small order accepted 6.Excellent antitrust technology 7.Long life 8.Large size range: inner diameter from 10mm-780mm. 9.Variations of structure: 7000/70000Series 3200/3300 Series QJ/QJF Series 10. Physical Characteristics: 1)Angular contact ball bearing is particularly suitable for carrying combined (axial and radial) loads. Sometimes, they also can carry pure axial load and operate in higher speed. Under radial load, axial component force will be produced which must be counteracted. So the bearing is normally adjust against a second bearing. 2) Type of angular contact ball bearing: Single row angular contact ball bearing, Double row angular contact ball bearing, Four-point angular contact ball bearing 3) Advantages of Angular Contact Ball Bearing: 1.Ultra clean steel to extend bearing life by up to 80% 2.Advanced grade technology 3.Quiet and smooth operation even at high speed 4.Super finished raceways 5.Offer products in 15,25 ,30and 40 degree angles 6.Available in arrange of Poly-amide, steel and brass cage assembles 4) Angular contact ball bearing can be used for Bed spindle, high frequency motor, gas steam turbine, centrifugal separator, the small car front differential pinion shaft, booster pump, drilling platform, food machinery, dividing head, welding, low noise type cooling tower, electrical and mechanical equipment, painting equipment, machine tool groove plate, arc welding machine oil pump, roots blower, air compressor, various types of transmission, fuel injection analysis equipment, the fine chemical mechanical pump, printing machinery, planetary reducer, extraction equipment, cyclonic reducer, food packaging machinery, electric welding machine, electric iron, square box, gravity spray gun, wire stripping machine, semi axis, inspection and so on. |
Product Processes
No.1:Chemical composition of raw material inspection:
High carbon chromium bearings steel Gcr15 is the standard material for precision bearing rings and balls.The material has uniform specification as AISL 52100(America),DIN100Cr6(Germany),JISSUJ2(Japan)
| Steel No. | Chemical Composition % | ||||||||
| C | Si | Min | P | S | Cr | Mo | Cu | Ni | |
| Gcr 15 | 0.95-1.05 | 0.15-0.35 | 0.25-0.45 | s0.025 | s0.025 | 1.40-1.65 | - | s0.25 | s0.30 |
No.2: Forging
We will put the raw material for forging processing.
No.3:Inner & outer rings grinding
1), After forging,we will begin grinding preliminary.Heat treatment.
2),After the heat treatment, begin surface grinding
3),After the surface grinding,then begin the second grinding--- Outer ring outer grinding and inner ring inner diameter grinding; Outer ring inner diameter grinding (raceway) and inner ring outer diameter grinding (raceway). Channel is polish highly.
4).Super finishing. Rings have the superfinish surface and the channel is polish highly.
No.4:Assembly
We need to put the inner ring,outer ring,steel ball,cage together,and then we need to fill the grease.
