spindle for rolling mill bearings Cylindrical Roller Bearing NU304M
The future of spindle for rolling mill bearings Cylindrical Roller Bearing NU304M
cylindrical roller bearings are separable bearings,the rollers are guided by the two ribs of bearing rings.The cage,rollers and guide ring are assembled to a unit, and can be separated from the other ring. These bearings are easy to be mounted and dismounted, especially inner and outer rings interference fit with shafts and housings.
Product Name:Cylindrical Roller Bearing
1.single row cylindrical roller bearings, caged ,mainly of the NU,NJ NUP and N designs
2.double row cylindrical roller bearings ,caged,mainly of the NNU and NN designs
3.single row full complement cylindrical roller bearings ,mainly of the NCF and NJG designs
4.double row full complement cylindrical roller bearing bearings,mainly of the NNF design
5.multi-row full complement cylindrical roller bearings, with four or eight rows of rollers
6.Bearings of this type, the cylindrical rollers are in linear contact with the raceways. They have a
high radial load capacity and are suitable for high speeds.
7.There are different types designated as NU, NJ, NUP, N, NF (for single-row bearings), NNU, and NN (for double-row bearings depending on the design or absence of side ribs).
8.The outer and inner rings of all types are separable.
