Double-row spherical roller bearing with central flange Single-row spherical roller bearing (barrel bearing). Most spherical roller bearings are designed with two rows of rollers, allowing them to take very heavy radial loads and heavy axial loads.
A cylindrical roller bearing. Roller bearings are the earliest known type of rolling-element-bearing, dating back to at least 40 BC. Common roller bearings use cylinders of slightly greater length than diameter. Roller bearings typically have a higher radial load capacity than ball bearings, but a lower capacity and higher friction under axial ...
A double-row design has two rows of bearing balls. Advantages of double-row bearings as compared to single-row include that they can bear radial and axial loads in both directions. Double-row angular contact ball bearings have a steep mounting, which also can bear tilting effects. Other advantages of double-row bearings are their rigidity and ...
Slewing bearing designs range from single row ball or roller style, through double row ball or roller, triple row roller, combined (1 roller/ 1 ball) or wore guided raceways - each design having its own special characteristics and application. Old designs can have split rings to allow tight control on preload during assembly.
A spherical roller thrust bearing is a rolling-element bearing of thrust type that permits rotation with low friction, and permits angular misalignment. The bearing is designed to take radial loads, and heavy axial loads in one direction. Typically these bearings support a rotating shaft in the bore of the shaft washer that may be misaligned in ...
Sven Gustaf Wingqvist (10 December 1876 – 17 April 1953) was a Swedish engineer, inventor, and industrialist, and one of the founders of Svenska Kullagerfabriken (SKF), one of the world's leading ball bearing and roller bearing makers. Sven Wingqvist invented the multi-row self-aligning ball bearing in 1907.
