		NA2   (Normal Duty) NA2 type Ball Bearing is assembled into the various housings and it has an eccentric collar on the outside of the inner ring for locking to the shaft. Like UC Type Bearing, it can be used in any place and maintains the long bearing service life.
		RB2   (Normal Duty) RB2 type Ball Bearing has the straight outer diameter surface and can be used in the same manner as the normal bearing. The fixing to the shaft is made in a simple and reliable manner by use of the setscrew. Since it has the complete dust-proof construction, it is useful to reduce the machine cost.
		ER2   (Normal Duty) ER2 type Ball Bearing is prepared by providing the snap ring and lubrication groove at the outer diameter surface of RB2 Type. The positioning arrangement with the bearing unit can be achieved easily and the construction of the housing can also be simplified.
