3311D
Double Row Angular Contact Ball Bearings feature two rows of balls in a common outer ring with a 30° contact angle, enabling bidirectional axial load handling. Non-separable design with integral ribs ensures precise alignment. Ideal for high-speed, high-stiffness applications like machine tool spindles and automotive differentials.
Metral:
Symmetrical design for balanced radial/axial load distribution.
High stiffness reduces shaft deflection under combined loads.
Pre-lubricated options for maintenance-free operation.
