Cylindrical Roller Bearings
Key Features
The cylindrical roller is in line contact with the raceway, and the radial load capacity is large. It is not only suitable for bearing heavy load and impact load, but also suitable for high-speed rotation. CRB raceways and rolling element geometric shapes have been improved and designed to have higher load-bearing capacity. The new structural design of ribs and roller end faces not only improves the axial load-bearing capacity of the bearing, but also improves the roller end faces. The lubrication condition of the contact area with the rib improves the performance of the bearing. This type of bearing is mainly used in medium and large motors, generators, internal combustion engines, gas turbines, machine tool spindles, reduction gears, loading and unloading handling machinery, and various industrial machinery.
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 SKF 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
