NU 313 ECJ-Single Row Cylindrical Roller Bearings
NU 313 ECJ-Single Row Cylindrical Roller Bearings with Stamped steel cage, rolling element centred.It can adjust the size of the clearance during installation.The ability to bear axial load depends on the contact angle, that is, the angle of the outer ring raceway. The larger the angle, the greater the axial load capacity.
