Product Description

Key Features of Double Row Angular Contact Ball Bearing

(Custom configurations available upon request.)

High Load CapacityDesigned to support combined radial and axial loads in both directions, making them ideal for applications with varying load demands.
Enhanced durability due to the symmetrical design that distributes loads evenly across both rows of balls.
Compact DesignCombines two single-row angular contact ball bearings into one unit, reducing overall assembly space while maintaining performance.
Suitable for installations where space constraints are critical.

Enhanced RigidityDouble-row configuration increases structural rigidity, providing greater stability for precision applications.
Sealing OptionsAvailable in open (unsealed), shielded (ZZ), or sealed (2RS) versions to meet diverse environmental requirements.
Sealed versions offer added protection against dust, moisture, and contaminants, extending bearing life.
Low MaintenancePre-lubricated designs minimize maintenance requirements and downtime.
Suitable for high-speed operations due to precision engineering and low-friction materials.
