The SKF assortment of matched single row tapered roller bearings (fig. 1) is based on popular sizes of single row tapered roller bearings. Depending on the application requirements, matched tapered roller bearings are available in different designs and variants: matched bearings arranged face-to-face matched bearings arranged back-to-back matched bearings arranged in tandem basic design and SKF Explorer bearings The matched bearings listed in the product tables constitute the basic SKF assortment. SKF can supply other matched bearings on request. Bearing features High load carrying capacity Depending on the design, matched bearings are suitable for heavy radial and axial loads. The axial load carrying capacity of tapered roller bearings increases with increasing contact angle α. The size of the contact angle, which is usually between 10° and 30°, is related to the calculation factor e (→ product tables): the larger the value of e, the larger the contact angle. Axial loads in both directions Depending on the design, matched bearings can locate the shaft axially in both directions with a specific axial clearance or preload. High stiffness Depending on the design, matched bearings can provide a relatively stiff bearing arrangement. Delivered as a set The bearings and ring spacer(s) are matched in production, are delivered as a set and are ready-to-mount. Low friction The projection lines of the raceways of each single bearing meet at a common point on the bearing axis (apex point A, fig. 2) to provide a true rolling action and therefore low frictional moments during operation.
