Angular Contact Ball Bearing
arrangement.
These bearings have contact angles between the rings and balls. The standard angles are 15°\25the higher the axial load carrying capacity of the bearing. However, the smaller contact angle, the higher the rotating speed.
Single row bearings can carry radial load and axial load in one direction.
Double-row angular contact ball bearings have two designs of one outer ring and two inner rings and one outer ring and one inner ring. For the design with one outer ring and two inner rings, the axial clearance is easy to control during machining.
Angular contact ball bearings are applied for high speed and high precision rotating condiations.
These bearings are mainly applied in the machine tool spindles,high-frequency motors, gas turbines, oil pumps,air compressors, printing machines and other installations.
According to dimension tolerances and runout accuracy, Nide deep grooveball bearings are ranged from ABEC-1 to ABEC-7, ABEC-1 is standard grade, whileABEC-3 is higher, ABEC-5 is much higher and ABEC-7 is the highest. Thesetolerance grades are according to the international standard (ISO-492).
ABMA | ISO/DIN | JIS |
ABEC-1 | P0 | Class 0 |
ABEC-3 | P6 | Class 6 |
ABEC-5 | P5 | Class 5 |
ABEC-7 | P4 | Class 4 |
