Bearing performance is not only determined by load or speed ratings. There are a number of other factors that contribute to bearing performance. To a large extent, performance is influenced by the geometry of the rollers, raceways and cages, the heat treatment, as well as the surface finish of all contact surfaces. Main factors which influence B7230-C-T-P4S Bearing 150x270x45mm performance include, but are not limited to:
Symmetrical rollers
Symmetrical rollers self-adjust , providing optimal load distribution along the roller length. This keeps stresses low under all load conditions and extends bearing service life.
Roller tolerances
The rollers in an B7230-C-T-P4S Bearing 150x270x45mm are manufactured to extremely tight tolerances for dimension and form. Each roller is virtually identical in size and shape to the other rollers in the set. This optimizes load distribution over the rollers to maximize bearing service life.
Special roller profile
The roller profile determines the stress distribution in the roller/raceway contact area. The special profile distributes loads more evenly along the rollers and prevents stress peaks at the roller ends to extend bearing service life .
Self-guiding rollers and a floating guide ring between the two rows of rollers Self-guiding rollers reduce friction and frictional heat . B7230-C-T-P4S Bearing 150x270x45mm floating guide ring guides unloaded rollers so that they enter the load zone in the optimal position.
Metal cages All B7230-C-T-P4S Bearing 150x270x45mm contain strong metal cages. This enables them to tolerate high temperatures and all lubricants.
