Straight hole open type

The straight hole open type self-aligning ball bearing is the basic universal type of self-aligning ball bearing. It adopts a classic structure of cylindrical straight hole inner ring+open unsealed+double row steel balls+outer ring spherical raceway. The core has the characteristics of self centering, easy installation, and flexible lubrication. It is mainly suitable for light medium load and large coaxiality deviation working conditions. It has no taper, no seal, and no additional locking structure. It is one of the most widely used basic bearings in industrial equipment and is suitable for general light medium load scenarios such as textiles, conveyors, agricultural machinery, and reducers.
