Cylindrical roller bearings FAG

Cylindrical roller bearings

Cylindrical roller bearings with cage

The cylindrical roller bearings are very rigid, can support high radial loads and, due to the cage, are suitable for higher speeds than the full complement designs.

Low-friction cylindrical roller bearings

Low-friction cylindrical roller bearings LSL and ZSL are single row, self-retaining and correspond to dimension series 23.

High precision cylindrical roller bearings

Cylindrical roller bearings of this type are double row precision bearings for machine tools.

Full complement cylindrical roller bearings

Full complement cylindrical roller bearings are available as non-locating, semi-locating and locating bearings and in single and double row designs.

Cylindrical roller bearings with snap ring grooves

Cylindrical roller bearings with snap ring grooves are full complement, self-retaining units comprising solid inner and outer rings, rib-guided cylindrical rollers and sealing rings.

 

 

Cylindrical roller bearings SKF

Cylindrical roller bearings

SKF cylindrical roller bearings are available in many designs, series and sizes. The majority are single row bearings with a cage. High-capacity bearings, double row bearings, multi-row bearings, single, double and multi-row full complement bearings (without a cage) and split bearings complete the SKF standard assortment provided here.

Single row cylindrical roller bearings

Single row cylindrical roller bearings are separable i.e. the bearing ring with the roller and cage assembly can be separated from the other ring.

Double row cylindrical roller bearings

Double row cylindrical roller bearings have a low cross section, high load carrying capacity and high stiffness. Therefore they are mainly used in machine tools, rolling mill stands, plastic calenders, grinding mills and also large gearboxes.

Multi-row cylindrical roller bearings

The low bearing cross section allows for relatively large roll neck diameters in comparison with the roll diameter. Since very many rollers can be incorporated, the radial load carrying capacity is exceptionally high.

Single row full complement cylindrical roller bearings

The basic SKF assortment of single row full complement cylindrical roller bearings provided here includes NCF and NJG design bearings. They are used to locate the shaft axially in one direction and eventually to accommodate axial displacement of the shaft relative to the housing in the opposite direction.

Double row full complement cylindrical roller bearings

The basic SKF assortment of double row full complement cylindrical roller bearings provided here includes NNCL , NNCF and NNC open design bearings, as well as sealed NNF design bearings.

Multi-row full complement cylindrical roller bearings

Multi-row full complement cylindrical roller bearings are mainly used in small cold rolling mills where very considerable rolling forces occur but where rolling speed is limited. Other applications for these bearings include straightening machines, shears and extruders.

 

 

Cylindrical Roller Bearings NSK

Cylindrical-Roller-Bearing_rgb

In 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.

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).

Cylindrical Roller Bearings NTN

cylindrical-roller-bearings

Cylindrical roller bearings have rollers that provide a modified line contact with the cylindrical inner and outer ring raceways, while the rollers are guided by ground ribs on either the inner or outer ring. The cylindrical shape allows the inner ring to have axial movement relative to the outer ring.
