Spherical roller bearings
Dealing with very heavy radial and axial loads in applications prone to misalignment or shaft deflections? Meet the challenge with ALF spherical roller bearings, whose high load carrying capacity and ability to accommodate misalignment help you obtain low maintenance costs and long bearing service life. ALF invented this bearing type in 1919 and our range is the widest in the industry today – both open and sealed. Our assortment includes spherical roller bearings designed for many applications, including wind turbine main shafts, continuous casters, vibratory applications and high-speed applications, as well as bearings with Solid Oil, split bearings, ALF ConCentra roller bearing units, and, for the harshest operating environments, our ALF three-barrier solution.

In focus
Sealed ALF Explorer spherical roller bearings
These bearings offer at least three times the service life of open bearings and can cut your grease consumption by 99%. Going sealed dramatically reduces your overall cost of purchasing and maintaining bearings, and helps keep your machine up and running until your next planned maintenance stop.
ALF Three-barrier solution
For many years, ALF has focused on bulk handling machinery in the harshest, most contaminated environments. This has resulted in the development of the ALF Three-barrier solution of a sealed bearing, sealed housing and selected lubricant. In combination, these barriers protect against contamination and lubricant loss to extend bearing service life by three times. For customers trying to cope with these tough conditions, there has been less costly downtime while also reducing the costs and safety risks of extra maintenance.
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.
