New range of spherical roller bearings included in NSK guideNSK is expanding its range of spherical roller bearings (SRBs). The development of two additional series of SRBs that cater for either speed or load as a priority, the 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 a 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 suitable in heavy applications.

NSK has developed some of the leading technology in bearing design. While many applications may require super high-precision or zero-maintenance designs, there remains a large market for the more general purpose, heavy duty design of SRB; this is further addressed by the 222 and 223 series, now available from NSK Europe.

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 per cent greater load rating and comes in 22 different sizes, which provides a bearing option for a wide range of applications.

Further information is available from NSK in the form of a guide Spherical Roller Bearings – RHP, catalogue reference RSR/A/E/06.13, which can be downloaded from the website at www.nskeurope.com.
