Cylindrical roller bearings SKF

โดย | ม.ค. 12, 2016 | Roller bearings

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.

 

 

Angular contact ball bearings SKF

SRACBB-with-M-cage

Angular contact ball bearings have raceways in the inner and outer rings that are displaced relative to each other in the direction of the bearing axis. This means that they are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads.

Single row angular contact ball bearings

SKF single row angular contact ball bearings can accommodate axial loads in one direction only. A single row bearing is typically adjusted against a second bearing.

Double row angular contact ball bearings

SKF double row angular contact ball bearings correspond in design to two single row angular contact ball bearings arranged back-to-back, but take up less axial space.

Four-point contact ball bearings

Four-point contact ball bearings are radial single row angular contact ball bearings with raceways that are designed to support axial loads in both directions.
