Overview of Single row self-aligning roller bearings
Single row self-aligning roller bearings (also called “Barrel Bearings”) are a kind of roller bearings that have solid outer rings with a concave raceway, solid inner rings with two ribs and a cylindrical or tapered bore as well as barrel rollers with cages.
Single row self-aligning roller bearings are particularly suitable where high radial shock type loads occur and misalignments must be compensated; see the section on the compensation of angular misalignments. They have only a low axial load-carrying capacity.
Single row self-aligning roller bearings Features:
Single row self-aligning roller bearings with solid brass cages have the suffix MB. The cages are guided on the inner ring. Solid window cages made from glass fiber reinforced polyamide are indicated by the suffix TVP.
Applications of Single row self-aligning roller bearings:
Single row self-aligning roller bearings are suitable for compensating angular misalignments where there is skewing between the outer and inner ring. As a result of the line contact between the rolling elements and raceways, they can support very high radial loads, even if shock-type loads occur. In contrast, axial load carrying capacity is low.
The use of Single row self-aligning roller bearings has benefited many industries:
Metalworking
Marine
Industrial gearboxes
mining machinery
Chemistry
Textile machinery
