Cylindrical Roller Bearings

Supplier: Nachi Australia

Construction of this roller bearing type is the simplest of all radial roller bearings. This bearing type is often used in high-speed applications. Because the inner ring, outer ring, and rollers are in line contact, this bearing type has a large radial load capacity.

Price Guide: POA

Various Cylindrical roller bearing configurations are: N,NJ,NF,NU,RNU : integral ribs (flanges) NH,NP ,NUP ,NUB : integral and loose ribs NN,NNU : double-row bearings.Configurations having integral flanges or loose ribs on both the inner and outer rings can sustain a small amount of axial load.

Since this bearing type supports axial loads as sliding action between the end of the rollers and flange faces, axial loading is limited. Double-row Cylindrical roller bearings are used for high-speed, high-accuracy applications such as; main spindle support for lathes, milling machines, and machining centers.

Radial clearance of tapered-bore bearings can be adjusted during mounting of the bearing(s) onto the mating journal. Standard cages are pressed steel or polyamide resin. Machined cages of high-strength brass are used for bearings of large dimension or for high- speed applications.
