SKF bearings produce many different types of cylindrical roller bearings with different dimensions, scales and sizes. Most of them are single row bearings with one cage. Plus single row and double row full roller bearings (without cage); constitute SKF Bearing type specification for general engineering. Bearings with cages can accept heavy radial loads; and can run at high speed. Full-roller bearings are suitable for very heavy radial loads at medium speed.
As for the SKF cylindrical roller bearing; the roller is the key component in between. Its several shapes; the so-called logarithmic shape; the optimal stress distribution is provided in the contact area of ​​the bearing. The surface finish promotes the composition of the lubricant oil film to the maximum limit; And optimize the roll of the roller. Compare with the traditional depiction; the advantages obtained include the improvement of operational reliability; and the greater tolerance of misalignment.
The types of SKF cylindrical roller bearings include the following basic types:
C single row cylindrical roller bearings with cage; double row cylindrical roller bearings with C cages for NU, NJ, NUP and N; multi-row cylindrical roller bearings for C-cage cages mainly for NNU and NN ;
C single row full complement cylindrical roller bearings; mainly for NCF and NJG depicting C double row full complement cylindrical roller bearings mainly for NNF depicting C multi-row full roller cylindrical roller bearings; with four or eight column roller addition Outside the specification; SKF cylindrical roller bearings also include:
C single row high precision all steel or ceramic cylindrical roller bearings,
C double row high precision all steel or ceramic cylindrical roller bearings,
C Cylindrical roller bearings and bearing equipment for railway axleboxes,
C Single row cylindrical roller bearings for traction motors used in railway applications,
C Open or sealed multi-row cylindrical roller bearings for rolling mills,
Support bearing for multi-roller cold rolling mill,
Indexing roller assembly for successive smelting furnaces.
