  Tapered Roller Bearings    
 


Request for QuoteThe angular construction of single row tapered roller bearings provides a high capacity for radial, axial, and combined loads.

Tapered roller bearings are made up of four interdependent components: The inner ring, or cone; the tapered rollers, or rolling elements; the roller retainer, or cage(collectively known as the cone assembly); and an outer race, or cup. They're designed and manufactured to ensure that their conical rollers and raceways are arranged so that their contact surfaces converge at a common apex on the bearing’s axis. The larger this contact angle the greater the bearing’s loading capacity.

By design, when a pure radial load is applied to a tapered roller bearing an axial load is also induced. It's for this reason that these bearings are normally mounted as opposing pairs. Proper running clearance or preload can be set through the distance separating a given pair on the shaft. Both metric and inch series cups and cone assemblies are ISO or AFMBA standardized, dimensionally, and are therefore interchangeable within each dimensional standard. It should be noted that high precision cups and cone assemblies are generally not interchangeable.
