Overview of Self-aligning ball bearings-open type
Self-aligning ball bearings-open type is a kind of self-aligning ball bearings with two rows of balls, a common sphere raceway in the outer ring, and two deep uninterrupted raceway grooves in the inner ring. The open type means the bearings are not sealed.
Product Features and Benefits:
- Accommodate static and dynamic misalignment
-The bearings are self-aligning like spherical roller bearings or CARB bearings.
-Excellent high-speed performance
-Self-aligning ball bearings generate less friction than any other type of rolling bearing, which enables them to run cooler even at high speeds.
-Minimum maintenance
-Because of low heat generation, the bearing temperature is lower, leading to extended bearing life and maintenance intervals.
-Low friction
-Very loose conformity between balls and outer ring keeps friction and frictional heat at low levels.
-Excellent light load performance
-Self-aligning ball bearings have low minimum load requirements.
-Low noise
-Self-aligning ball bearings can reduce noise and vibration levels, for example, in fans.
Applications of Self-aligning ball bearings-open type:
Self-aligning ball bearings open type are suitable for applications that involve misalignment between the axis and housing centers, axis deflection, etc. Using an adapter facilitates the mounting of a tapered bore bearing on the axis.
Self-aligning ball bearings open type can be applied in the following industries:
-Industrial fans
-Agriculture
-Material handling
-Food and beverage
-Pulp and paper
