» Four-point contact ball bearings – two in one

25/6/2015· Four-point contact ball bearings (QJ bearings) are a specific type of angular contact ball bearings. In many appliions one QJ bearing is an interesting alternative to a matched set of single-row angular contact ball bearings. Indeed, its space-saving design, the speed capabilities and the load carrying capacity are remarkable.

Duplex Bearing Arrangements - Back to Back, Face to Face and …

13/1/2013· When the bearings are installed and clamped axially, the gap is closed producing a preload on the bearings. There are three types duplex bearing arrangements commonly used and they are Back to Back, Face to Face and Tandem bearing arrangement. Bearings that are normally duplexed are angular contact ball bearings and tapered roller bearings.

How to properly mount thin section bearings: a new Kaydon Bearings …

When these bearings are mounted in a back-to-back (DB) arrangement, the arrows should point away from each other. In a face-to-face (DF) arrangement, the arrows should point toward each other. Angular contact bearings purchased as a matched (duplex) set will have a "V" marked across the O.D. and I.D. of both bearings.

Duplex bearings | Principle Engineering

Duplex bearing O (<>) arrangement: Back to back (designation –1 and DB for spindle bearings) With this bearing configuration the inner rings are designed to be clamped together. The contact angle load path between the outer ring raceway, the ball and the inner ring curvature diverge, which results in maximum stability and stiffness against any moment loading.

Reali-Slim® type A angular contact thin section bearings | Kaydon Bearings

A back-to-back arrangement offers greater rigidity under moment loading and should be used when the space between single bearings is small or when a single pair of adjacent bearings is employed. A face-to-face arrangement is more tolerant of misalignment between the shaft and housing and should be considered when there are multiple pairs of bearings along an axis.
