tapered roller bearing

Description

Tapered bearings are uniquely designed to manage both thrust and radial loads on rotating shafts and in housings. We manufacture nearly *6, **0 bearing combinations – in single, double and four-row configurations. Customized geometries and engineered surfaces can be applied to these bearings to further enhance performance in demanding applications. Tapered roller bearings consist of four interdependent components: the cone, or inner ring; the cup, or outer ring; the tapered rollers, or rolling elements; and the cage, or roller retainer. The taper angles allow the bearing to handle a combination of radial and thrust loads. The steeper the cup angle, the greater the ability of the bearing to handle thrust loads. Tapered roller bearings have tapered inner and outer ring raceways between which tapered rollers are arranged. The projection lines of all the tapered surfaces meet at a common point on the bearing axis. Their design makes tapered roller bearings particularly suitable for the accommodation of combined (radial and axial) loads. The axial load carrying capacity of the bearings is largely determined by the contact angle αthe larger α, the higher the axial load carrying capacity (An indication of the angle size is given by the calculation factor e; the larger the value of e, the larger the contact angle and the greater the suitability of the bearing for carrying axial loads. Tapered roller bearings are generally separable, ***** the cone, consisting of the inner ring with roller and cage assembly, can be mounted separately from the cup (outer ring). tapered roller bearings have the logarithmic contact profile that provides optimum stress distribution over the roller/raceway contacts. The special design of the sliding surfaces of the guide flange and large roller ends considerably promote lubricant film formation in the roller end/flange contacts. The resulting benefits include increased operational reliability and reduced sensitivity to misalignment.
