ISO9001:2008 ISO/TS16949:2002 Different structure and size Produce by customer's needs
The structure of cylindrical roller bearing is distinguished in accordance with the different shoulders. Model NU cylindrical roller bearing has the outer ring with two shoulders and one inner ring without shoulder. As for Model N cylindrical roller bearing, the inner ring has two shoulders and the outer ring has no shoulder. Model NU, N cylindrical roller bearings are running bearings. The inner ring and outer ring can be separated conveniently for mounting and dismounting. As for Model NJ cylindrical roller bearing, the outer ring has double shoulders and the inner ring has single shoulder. As for Model NF cylindrical roller bearing, the inner ring has double shoulder and the outer has single shoulder, they can withstand the single-directional axial force. Model NUP cylindrical roller bearing is used as fixing bearing, withstanding the alternate directional axial force. The outer ring of it has double shoulder and one baffle ring.
DESIGN CLASSIFICATION
Single Row Cylindrical Roller Bearing
Single row cylindraical Roller Bearing can be classified in NU,NJ,NUP,N,NF and so on .Inner ring outer ring are separeable.It can bear axial load from one direction.It's generally made of dteel stamping or brass cage and some of them are using cage of formed polyamide.
DESIGN CLASSIFICATION
1.The roller and raceway are line contact.Great radial load rating capacity and can bear heavy load and impact load.
2.Small frictional factor.Suitable for high-speed.Its limiting speed is nearly the same as deep groove ball bearings
3.Inner ring and outer ring are separable which is favorable for assembly and disassembly.
CAGE CLASSIFICATION
1.EM double assembly machine process copper cage with outer ring or inner ring centered.
2.EM pressed steel cage with rollers centered.
3.EP-nylon cage with rollers centered.
PRODUCT ADVANTAGE OF TOWE
1.Improving cage design
2.Optimizing design of bearings ribs9can bear higher axial load)
3.Smaller tolerance of roller(average load is well distributed)
