Description of SKF Cylindrical Roller Bearings:
1. 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.
2. Bearings with a cage can accommodate heavy radial loads, rapid accelerations and high speeds. Full complement bearings incorporate a maximum number of rollers and are therefore suitable for very heavy radial loads at moderate speeds. SKF high-capacity cylindrical roller bearings combine the high load carrying capacity of a full complement bearing with the high speed capability of a bearing with a cage.
3. The factors that influence SKF cylindrical roller bearing performance and service life include but are not limited to the following:
(1) Roller end / flange contact area
(2) Logarithmic roller profile
(3) Surface finish
(4) Interchangeable components
Different types of SKF Cylindrical Roller Bearings:
1. SKF 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. This simplifies mounting and dismounting, particularly when load conditions require both rings to have an interference fit.
2. SKF 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.
SKF produces double row cylindrical roller bearings mainly in the NNU design and the NN design. The bearings are separable, i.e. the ring with integral flanges together with the roller and cage assemblies can be mounted separately from the other bearing ring or all bearing components can be mounted separately. This facilitates the mounting, inspection and maintenance of these bearings.
3. SKF Four-row and six-row cylindrical roller bearings are used almost exclusively for the roll necks of rolling mill stands, calenders and roller presses. Their friction is low compared with other roller bearings. As they are normally mounted with an interference fit on the roll neck, they are particularly suitable for rolling mill applications where the rolling speed is high.
The four-row and six-row cylindrical roller bearings are of separable design, i.e. the ring or rings with integral flanges and the roller and cage assemblies can be mounted independently of the free rings, or all bearing components can be mounted separately. This considerably simplifies bearing mounting, maintenance and inspection. A certain limited axial displacement of the shaft with respect to the housing can be accommodated within the bearing.
4. SKF 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. (NCF bearings, NJG bearings)
5. SKF 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. All bearings are non-separable and have an annular groove and three lubrication holes in the outer ring to facilitate lubrication. NNF design bearings have three additional lubrication holes in the inner ring.
6. SKF 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. To facilitate efficient lubrication, all multi-row full complement cylindrical roller bearings have lubrication holes, or an annular groove and lubrication holes in the outer ring.
