Cylindrical Roller Bearings
ALF 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.
Product types

- Cylindrical roller bearings and bearing units for railway applications (contact ALF)
Features and benefits
- High load carrying capacity
- Long service life
- Accommodate axial displacement (fig. 1)
Except for bearings with flanges on both the inner and outer rings. - Low friction
The open flange design (fig. 2), - 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 (fig. 3) 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 ALF cylindrical roller bearings are interchangeable (fig. 4). This facilitates mounting and dismounting, as well as maintenance inspections.
Applications
ALF 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
In focus
ALF Explorer performance for large, heavy-duty applications
When compared to non-ALF Explorer cylindrical roller bearings, ALF Explorer cylindrical roller bearings undergo a number of enhancements, designed to improve reliability and increase the service life of the bearing even in the most demanding applications.
Bearing remanufacturing
Replacing industrial bearings can be expensive and energy-consuming. Bearing remanufacturing offers a cheaper, more environmentally sustainable option. We use a combination of reused, repaired and new parts to rebuild your bearing to the specifications of the original manufactured product.
