The main and connection dimensions of the bearings specified in the dimension tables are in accordance with the international standards ISO 15 (STN 02 4629).
Single row angular contact ball bearings α = 26°, α = 40°
The group of single row angular contact ball bearings comprises of bearings with contact angle α = 26° and α = 40° designed for standard seating and the high-precise single row ball bearings designed for high rotation speed.
These products have deep raceway that enables the absorbtion of radial load at relative heavy axial load in single direction. The bearings are mounted in pairs – face to face or back to back – in order to absorb the axial load in both directions.
Single row angular contact ball bearings designated for high rotation speed and high precision of seating differ from standard angular contact ball bearings by inner design of bearing rings, contact angle dimension of the ball with the raceways of the rings, construction of cage, high precision degree of operation. The bearings are non-separable and their correct arrangement assures required firmness and precision of seating. The bearings have textite cage guided on the inner ring (TB) or on the outer ring (TA).
Single row angular contact ball bearings are commonly produced in tolerance classes P0 and P6 according to the standard ISO 495. Production of bearings with higher tolerance class (P5 or P4) should be discussed in advance.
