THE MOST IMPORTANT BREAKTHROUGH IN ALMOST 60 YEARS...

When CARB™, after several years of intense development work, was introduced in the mid 1990's it was a revolution in bearing technology. The toroidal roller bearing was born.
Never before had a new bearing concept so many new features to offer. The inventor's hopes of creating a bearing that could take angular misalignment as well as axial displacement and higher load were satisfied more than well.
It is a fact that all new bearing types developed during this century have been developed by SKF. The toroidal roller bearing concept only confirms SKF's role as the world's leading bearing manufacturer.

ALL BEARING TYPES HAVE ADVANTAGES. THE TOROIDAL ROLLER BEARING HAS ALL THE ADVANTAGES.

A cylindrical roller bearing tolerates axial displacement, but not angular misalignment. A spherical roller bearing tolerates angular misalignment, but not internal axial displacement. A needle roller bearing is compact and tolerates axial displacement, but not misalignment.
The toroidal roller bearing combines the advantages of these three bearing types without any of their disadvantages.
Whether you are working with machine maintenance or mechanical design, CARB will give you a whole new perspective on cost efficiency.

INCREASE AVAILABILITY, REDUCE MAINTENANCE ...
Premature failure in conventional roller bearings is often due to manufacturing deviations and deformation in operation that cause uneven load on rollers.
A CARB, where the load is always evenly distributed over the roller length, will run for its full life where others fail prematurely. Thus, it will help you increase machine availability as well as reduce maintenance.

... AND BOOST PERFORMANCE.

As CARB handles axial displacement internally, it helps to reduce vibration in a machine and thus allows higher machine speed.
For heavy-duty machines, CARB mean more savings, less maintenance and higher productivity. For consumer products, CARB means lower service and repair costs and increased customer satisfaction.
CARB is definitely a user-friendly bearing.

REDUCE SIZE, WEIGHT AND MANUFACTURING COSTS.
The toroidal roller bearing offers many challenges for the experienced mechanical designer.
It permits smaller and lighter designs where bearing size previously prohibited downsizing. In some cases CARB not only enables downsizing of the bearing arrangement, but also downsizing of the entire machine design.
Since manufacturing costs for most machines are related to size and weight, CARB can help you to design more competitive products as well as to reduce manufacturing costs by downsizing.
We will help you accept the challenge.

APPLICATIONS.
The toroidal roller bearing concept offers several benefits for a
wide range of application areas. The general, most important benefits are high carrying capacity, more compact and less complex designs, reduced weight and manufacturing costs, increased reliability, longer bearing service life and lower vibration levels. CARB bearings are already used in applications such as planetary gearboxes, industrial gearboxes,
continuous casting machines, fans and blowers, drying cylinders and felt rolls in paper making machines. All with great success. The most recent - and equally successful - applications for CARB are electric motors, sugar cane

shredders, mobile cranes/wheels on rails, compressors, vehicle gearboxes, intermediate gears on dumper trucks, rolling tables in steel works and wind energy plants.
Do you see a possible use of CARB in your field of action, but you don't find it mentioned above? Don't worry, the world of CARB users are growing rapidly
