Special Double Row Ball Bearings for Textile Machines and Measuring Instruments

Special double-row bearing for textile machines and measurement instruments built not separable unit, which consists of cylin-drical bushing and shaft, arranged in two rows of balls. The balls are led in light one-sided cages. The raceways on the shaft and inthe cylindrical bushing are made in high accuracy degree. Effective contact or non-contact seals on both sides of bearings preventpenetration of impurities. The bearings are filled with a grease of a high quality providing constant lubrication during their wholelife. In some cases the design of the bushings makes possible relubrication during a bearings life.

A special double-row bearing creates a complete bearing unit which enables simple assembly and maintenance. The develop-ment of these bearings hangs together with a solution of arrangements of the most important parts in the textile machines but alsofor measuring instruments.

Special double-row ball bearings for textile machines are designed for high rotational speed and relatively light load. They areknown for they high dimensional accuracy and smooth run warranting their high effectiveness. KINEX, a. s., Bytča, produces and sup-plies these bearings according to demand of the users complemented with some other components, e. g. pulleys drive discs andelastic bearings. In some cases there are complete integrated bearing units which make from the technological and economical pointof view possible the more effective production of textile machines.

Special double-row ball bearings for textile machines produced by KINEX, a. s., Bytča, are used in shaping machines such as spin-dles of torsional units, in non-spindle spinning machines by housing a bearing of spinning chamber, of a card strips disk etc.

Special double-row ball bearings for measuring instruments are known for their high dimensional accuracy as well as for opera-tional reliability, but they are working at lower rotational speeds as the bearings in textile machines. They are used e. g. for arrange-ments of measuring disc in incremental daffers.
