2 oel STO an RSTO support roller bearings As for oel STO supporting roller neele bearing with inner ring an without shouler, the outer ring of bearing is roller type with compact structure an thick wall. It can withstan large stock force in rotation with high abrasion-resistance. ecause of no shouler in the bearing, inner ring, neele, cage assembly an outer ring can be mounte respectively. If the surface of outer ring is cyliner face, the esignation of bearing is STOX. As for oel RSTO supporting roller neele bearing without inner an shouler, the bearing has no inner ring, so it is requeste that the surface harness an surface of shaft journal fitte with it be matche with bearing. The performance of this bearing is same as that of oel STO. If the surface of outer ring is cyliner face, the esignation of bearing is RSTO2.

It is suitable for heavy loa an mile rotational spee. Since the bearing has a large grease-storage space, it has a long-term lubrication cycle. oel KR PP curve roller has the contact-type seal structure. oel KRV, KRV PP urve Roller The structure of oel KRV, KRV PP curve roller bearing is same with that of oel KR, KR PP curve roller bearing. oel KRV, KRV PP curve roller bearing is the full complement neele roller bearing. This cure roller bearing can withstan heavy loa uner the low spee.

As same as parallel roller bearing, the outer ring is guie axially by rolling boy. The cover presse in outer ring an the shouler constitutes the high-efficient gas seal. This kin of cure roller bearing can withstan the heavy loa an the shock axial loa because it is guie axially by roller.
