Cylindrical roller bearings are characterized by high radial-, and moderate thrust-load capacities. They contain cylindrically-shaped roller, which are nevertheless not true cylinders. Instead, they are crowned or end-relieved to reduce stress concentrations. This particular geometry results in low friction and allows high-speed applications.
Spherical roller bearings are suitable for low/medium speed applications which involve heavy or impact loading. They come with cylindrical or tapered bores and can be supplied with adapter assemblies as well as withdrawal sleeves. These bearings are divided into R, RH(R) and RHA types, which differ in internal structure. Bearings with a tapered bore can be fit and removed easily using an adapter assembly or withdrawal sleeve.
Taper roller bearings consist of an inner ring (cone), an outer ring (cup), a cage and rollers which are profiled to distribute the load evenly. They have high radial and axial (thrust) load capacities at low to intermediate speeds. Taper roller bearings are available in single-row, two-row and four-row designs.
