heavy load conditions SKF tapered roller bearings have either crowned raceways or a logarithmic profile to prevent stress peaks at the roller ends The logarithmic profile is designed to optimize load distribution along the rollers … consistency of profiles and roller size The rollers used in SKF tapered roller bear ings are

Tapered roller bearings have tapered inner and outer ring raceways as well as tapered rollers They are designed to accommodate combined loads ie simultaneously acting radial and axial loads The projection lines of the raceways meet at a common point on the bearing axis (apex point A fig 1) to provide a true rolling
Depending on the application there may be a need to preload a bearing arrangement For example if a high degree of stiffness or positional control is required then preload may be suitable Similarly where there is a very light or no external load on the bearing in operation then preload may be required to ensure a
