The latest 222 and 223 SRB ranges are designed to meet the needs of the most demanding environments and are included in a new NSK guide designed to make the choice between these sometimes conflicting demands easier.
SRBs offer an unequalled combination of high load capacity, high tolerance to shock loads and self-aligning ability, however, these attributes are tempered by the limitation of maximum speed. The capacity to maintain dimensional stability, support high radial loads and moderate axial loads also makes the SRB an ideal product for heavy-duty applications.
Both series are available with either a steel or a machined brass cage, depending on the application requirements and are produced in sizes up to 400mm outside diameter. In addition, they are available with either a cylindrical bore or a 1:12 tapered bore, ranging from 25mm up to 220mm.
The 222 series is capable of running at higher speeds and is available in 27 different sizes, while the 223 series offers up to 50 percent greater load rating and comes in 22 different sizes, which provides a bearing solution for a wide range of applications.
