(Refer to te dimension table.) (4) ig self-aligning capability (rolling direction) Same as te combination in angular contact bearings, self-aligning capability is ig because te cross point of te contact lines of balls and grooves comes inside, reducing moment rigidity. is increases te capacity to absorb errors in installation.
