Double Row Angular Contact Bearings

Self-aligning ball bearings have two rows of balls, a common sphered raceway in the outer ring and two deep uninterrupted raceway grooves in the inner ring. This type of ball bearing is recommended when alignment of the shaft and housing is difficult, and the shaft may flex. Unlike a single row or double row ball bearing, the self-aligning bearing’s performance will not be affected by misalignment. Therefore, they are particularly suitable for application where misalignment can arise from errors in mounting or shaft deflection inherent in the application. These bearings are made with seal or without seal.

Although single row radial bearings are designed primarily to support a radial load, they perform relatively well under thrust or combined radial and thrust load with the added advantage of low noise, vibration, and drag torque. The internal architecture and cage selection can be designed to meet the specific needs of the application, from high speed to high load. Thin section deep groove ball bearings have a small radial cross-sectional thickness that are used when compactness is required. We manufacture deep groove ball bearings with a minimum bore diameter of 3 mm to a maximum outer diameter of 47 mm.

The noise level is an important quality criteria of a ball bearing. It mainly depends on the following factors: precision of the geometric forms surface finish of the raceway and the balls cleanliness of the bearing type of lubricant type of cage rotational speed

Pairing is achieved with bearings of identical tolerance classes and by applying an axial preload to the inner rings for the O arrangement and on the outer rings for the X arrangement. The inner or outer rings are undergo a separate grinding operation to align both side faces on the same plane with minimum clearance.
