708a  708 nsk angular contact ball size 8 22 7 mm bearing

 Angular Contact Bearing 

Size range:

cylindrical roller bearings the basic dimensions are listed in the data table size,

Diameter size range: 10mm ~ 45mm

Diameter size range: 22mm ~ 68mm

Width range: 6mm ~ 12 mm

Main Structure

(1).Single-row angular contact ball bearing

     single-row contact angular ball bearings have separable and non-separable designs,such as S7000

 series and SN7000 series.

(2).Double-row angular contact ball bearings

(3).Paired and matched ball bearings

2.Allowed angle of inclination

3.Tolearance and Clearance.

4..ISO9001:2000 standard

5.Material:bearing steel.

    Bearing precision: Auto Bearing accuracy mainly has Dimensional accuracy and Rotation accuracy. The precision has been standardized into six grades:grade 0/6X/6/5/4/2.

Precision is better from 0, 0 grade is for general purposes

6.Quality standards:China Bearing Standard: GB/T 307.3—1996, General rules for rolling bearing GB/T 307.3—1996. Bearing hardness:63°Hardness testing equipment: HRD-150type Electric Rockwell.

Design Attributes

· Specific geometry of angular contact bearing raceways and shoulders creates ball contact angles that support higher axial loads.

· Expanded options include special lubricants, cage materials, preloads and coatings for additional corrosion resistance.

Automotive bearings angular contact ball bearings Grease and rust

Automotive bearings are filled with the moderate Great Wall lithium grease for low-noise at the factory, therefore, be sure to use similar lithium grease to avoid grease deterioration when we add grease into bearings. It not better add too much.

Applications

Angular contact ball bearings are engineered for use in high-speed, high precision applications for:

· Agriculture

· Chemical

· General industry

· Utilities
