TVB produces cylindrical roller bearings in many designs, dimension series and sizes. The majority are single row bearings with a cage. Single and double row full complement bearings (without cage) complete the TVB standard assortment for general engineering. Bearings with a cage can accommodate heavy radial loads and operate at high speeds. Full complement bearings are suitable for very heavy radial loads at moderate speeds.
The rollers of cylindrical roller bearings are a key component. Their geometry, the so-called logarithmic profile, provides an optimum stress distribution in the contact zones in the bearing. Their surface finish maximizes lubricant film formation and optimizes rolling motion of the rollers. The benefits derived from this compared with traditional designs include enhanced operational reliability and a greater insensitivity to misalignment.
The TVB range of cylindrical roller bearings comprises the basic types
– | single row cylindrical roller bearings, caged, mainly of the NU, NJ, NUP and N designs |
– | double row cylindrical roller bearings, caged, mainly of the NNU and NN designs |
– | multi-row cylindrical roller bearings, caged |
– | single row full complement cylindrical roller bearings, mainly of the NCF and NJG designs |
– | double row full complement cylindrical roller bearings, mainly of the NNF design |
– | multi-row full complement cylindrical roller bearings, with four or eight rows of rollers |
In addition to the standard assortment the comprehensive SKF range of cylindrical roller bearings consists of
– | single row high-precision all-steel or hybrid cylindrical roller bearings |
– | double row high-precision all-steel or hybrid cylindrical roller bearings |
– | cylindrical roller bearings and bearing units for railway axleboxes |
– | single row cylindrical roller bearings for traction motors for railway applications |
– | backing bearings for cold rolling mills of the cluster type |
– | indexing roller units for continuous furnaces |
3. Materials:
Ring and cages: Chrome bearing steel
Balls: Chrome steel or carbon structural steel
Cover: Rubber or metal
Non-separable and require little attention or maintenance in service
Capable of operating at high speeds and are widely used radial bearings
Deep groove ball bearings are most commonly used rolling bearings
Can carry much heavy axial loads after increase of radial clearance
Can take the place of high speed angular contact ball bearings
Can used for carrying pure axial loads
Compared with other bearings with same dimensions
Lower friction and higher limited speed but lower impact
Widely used in automobiles, tractors, machine tools, motors, pumps, agricultural machinery, and textile machinery and other high speed facility
