Cylindrical roller bearings are available in a wide range of designs, series, variants and sizes. The main design differences are the number of roller rows and the inner/outer ring flanges as well as cage designs and materials.The bearings can meet the challenges of applications faced with heavy radial loads and high speeds. Accommodating axial displacement (except for bearings with flanges on both the inner and outer rings), they offer high stiffness, low friction and long service life.
- High load carrying capacity
- High stiffness
- Accommodate axial displacement
Except for bearings with flanges on both the inner and outer rings.
- Low friction
The open flange design together with the roller end design and surface finish, promote lubricant film formation resulting in lower friction and higher axial load carrying capability.
- Long service life
The logarithmic roller profile reduces edge stresses at the roller/raceway contact and sensitivity to misalignment and shaft deflection.
- Enhanced operational reliability
The surface finish on the contact surfaces of the rollers and raceways supports the formation of a hydrodynamic lubricant film.
SKF cylindrical roller bearings have characteristics that make them suitable for use in many types of industrial applications and essential for some. They can be used in both locating and non-locating bearing positions in bearing arrangements in for example:
- Stationary gearboxes
- Automotive gearboxes
- Electric motors
- Vibration motors
- Wind turbines
- Off-highway equipment
- Pumps and compressors
- Material handling equipment
- Textile machinery
- Rail vehicles
- Rolling mills
Single row cylindrical roller bearings are available in many designs, series and sizes.
Double row cylindrical roller bearings are available in several designs with a cylindrical or tapered bore.
Four-row cylindrical roller bearings are used almost exclusively for the roll necks of rolling mill stands, calenders and roller presses.

Single row angular contact ball bearings can accommodate axial loads in one direction only.
The design of the double row angular contact ball bearings corresponds to two single row angular contact ball bearings arranged back-to-back.
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.

Single row tapered roller bearings are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads.
The assortment of matched single row tapered roller bearings is based on popular sizes of single row tapered roller bearings.
Double row tapered roller bearings can accommodate heavy radial loads, axial loads in both directions and have a high degree of stiffness.

Cylindrical roller thrust bearings are designed to accommodate heavy axial loads and impact loads.
Needle roller thrust bearings are fitted with a form-stable cage to reliably retain and guide a large number of needle rollers.

Pillow block bearing units consist of an insert bearing mounted in a housing, which can be bolted to a support surface.
Flanged bearing units consist of an insert bearing mounted in a housing, which can be bolted to a machine wall or frame.
The take-up bearing unit assortment comprises of insert bearing series and designs, with the main differences between the take-up units being the housing design, the locking method onto the shaft, the sealing solution, and the options for end covers and back seals.
