Spherical roller bearing with a brass cage in a cut-through view. A spherical roller bearing is a rolling-element bearing that permits rotation with low friction, and permits angular misalignment. Typically these bearings support a rotating shaft in the bore of the inner ring that may be misaligned in respect to the outer ring.
A tapered roller bearing is a unit that consists of both tapered raceways (inner and outer rings), and tapered rollers. The construction is intended for combination loads, such as dual acting axial and radial loads. The bearing axis is where the projected lines of the raceway combine at a common location to improve rolling, while reducing friction.
Illustration of bearing tolerances (in micrometers) for a bearing with a 20 mm inner diameter. For illustration, the figure shows the differences in tolerance per ABEC class in micrometers (μm) for a 20 mm inner diameter bearing. [1] A 20 mm ABEC 7 bearing only has a 5 μm tolerance window, whereas an ABEC 1 has twice as wide a tolerance.
A spherical bearing is a bearing that permits rotation about a central point in two orthogonal directions (usually within a specified angular limit based on the bearing geometry). Typically these bearings support a rotating shaft in the bore of the inner ring that must move not only rotationally, but also at an angle.
S is the Sommerfeld Number or bearing characteristic number r is the shaft radius c is the radial clearance μ is the absolute viscosity of the lubricant N is the speed of the rotating shaft in rev/s P is the load per unit of projected bearing area. The second part of the equation is seen to be the Hersey number.
A jewel bearing is a plain bearing in which a metal spindle turns in a jewel-lined pivot hole. The hole is typically shaped like a torus and is slightly larger than the shaft diameter. The jewels are typically made from the mineral corundum , usually either synthetic sapphire or synthetic ruby .

Once the DN factor of a bearing has been obtained, it can be used to consult grease selection charts in order to determine the correct lubricant. Viscosity must be matched to the needs of the bearing in order to obtain maximum efficiency, and to avoid lubricant runout due to overheating, which is a consequence of metal-on-metal contact, as well ...
