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.
Cylindrical roller bearings are also available in sealed or split designs. In sealed bearings, the rollers are protected from contaminants, water and dust, while providing lubricant retention and contaminant exclusion. This provides lower friction and longer service life. Split bearings are intended primarily for bearing arrangements which are difficult to access, such as crank shafts, where they simplify maintenance and replacements.
Features and benefits
- 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. - Separable and interchangeable
The separable components of cylindrical roller bearings are interchangeable. This facilitates mounting and dismounting, as well as maintenance inspections.
Applications
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
Types NJ and NF can sustain limited axial loads in one direction.
Types NH and NUP can be used as fixed-end bearings.
NH-type cylindrical roller bearings consist of the NJ-type cylindrical roller bearings and HJ-type L-shaped thrust collars.
The inner ring loose rib of an NUP-type cylindrical roller bearing should be mounted so that the marked side is on the outside.
