Model STO and RSTO support roller
As for Model STO supporting roller needle bearing with inner ring and without shoulder, the outer ring of bearing is roller type with compact structure and thick wall. It can withstand large stock force in rotation with high abrasion-resistance. Because of no shoulder in the bearing, inner ring, needle, cage assembly and outer ring can be mounted respectively.
If the surface of outer ring is cylinder face, the designation of bearing is STO --X.
As for Model RSTO supporting roller needle bearing without inner and shoulder, the bearing has no inner ring, so it is requested that the surface hardness and surface of shaft journal fitted with it be matched with bearing. The performance of this bearing is same as that of Model STO.
If the surface of outer ring is cylinder face, the designation of bearing is RSTO2. As for Model STO support ing roller needle bearing with inner ring and without shoulder, the outer ring of bearing is roller type with compact structure and thick wall. It can withstand large stock force in rotation with high abrasion-resistance. Because of no shoulder in the bearing, inner ring, needle, cage assembly and outer ring can be mounted respectively.
If the surface of outer ring is cylinder face, the designation of bearing is STO---X. (Model STO and RSTO support roller).
As for Model RSTO supporting roller needle bearing without inner and shoulder, the bearing has no inner ring, so it is requested that the surface hardness and surface of shaft journal fitted with it be matched with bearing. The performance of this bearing is same as that of Model STO.
If the surface of outer ring is cylinder face, the designation of bearing is RSTO---XShaft
