Cylindrical Roller Bearings NJ (EG) C3 Clearance
- Internal Design: High Capacity Design (E).
- Cage Type: Nylon Molded Cage (G).
- C3 internal clearance, greater than the normal clearance.
- Cylindrical roller bearings are designed to have heavy radial load-carrying capacity.
- Cylindrical roller bearings are commonly separable and easy to mount and dismount.
- Rolling elements are ground to provide maximum contact with the raceway and are precisely crowned to avoid edge loading due to any shaft misalignments.
About Cylindrical Roller Bearings
- 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.
- 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.
Various Cylindrical roller bearing configurations are:
- N,NJ,NF,NU,RNU : integral ribs (flanges)
- NH,NP,NUP,NUH : integral and loose ribs
- NN,NNU : double-row bearings
