With 15% more than nominal life and some levels of noise minimised

Threads insertables and supports of INA, now in quality X-life

Editorial Interempresas17/07/2012

With more than 230 series for diameters between 10 and 120 millimetres, Schaeffler offers from June 2012 a wide system modulate of threads insertables and supports, available in quality X-life. This means greater life in service and reliability, with a simpler setting and a reduction of the maintenance.

These new threads X-Life combine an increase of the efficiency with a reduction of noise, until the point to work of form much more silent that the conventional threads.

Greater useful life and reliability, with a simpler setting and a reduction of the maintenance: the threads insertables and the supports of INA are available now in quality X-life.

Protection improved against the corrosion and greater nominal life

The threads insertables and supports X-life establish the new standard. The efficiency of the protection against the corrosion has triplicado in the threads insertables and in the supports of sheet of steel, thanks to the utilisation of the Corrotect N, instead of Corrotect To. At the same time, the nominal life has increased until 15% and have reduced the levels of noise, thanks to the improvement of the surface of the tracks of rodadura.

The rank of standard temperature has expanded until 180º in some series. The rings eccentric tensors convince thanks to the new materials used in his manufacture, attaining with them an increase of the strength of subjection in the axis. The reliable obturaciones increase the length of life of the threads and with this, the nominal life of the team. They keep the fat for threads of high quality inside the rolling and prevent the entrance of dirt and humidity.

The engineers of Schaeffler have developed an exclusive system of obturación from 3 components —covers external, lip obturador and covers inner—. The also called ‘concept sandwich' provides protection in front of practically all the conditions of operation and environingingmental. The special characteristics that improve of significant form the action of obturación, are the concentric surface of contact of the obturación, the mechanical protection thanks to that you cover them outsides extend around the centre of the rolling, cover inner and external galvanised and obturaciones of lip for standard applications or operation to high or low temperatures. Besides, the obturadores of sheet of steel ensure the fixation of the obturación and a reengrase simple.

Protection against the corrosion until thrice more effective, in the threads insertables and supports of sheet of steel, thanks to the superficial coating with Corrotect N.

All the threads insertables and supports X-life can fix in the axis, using five different methods. The standard methods are those that use a ring eccentric tensor or screws prisoners, whereas the fixation in the axis by means of adjust uses with less frequency. On the other hand, 2 special fixations of INA deserve to be mentioned of individual form. The first is a slot in the inner ring that compensates the expansion of the axis and the second is a manguito of fixation incorporated that allows to reach high speeds thanks to a method of concentric fixation. These threads are interchangeable with threads insertables radial with the same capacity of load and dimensions.

The threads insertables and the supports use in almost all the sectors of the industry. In the agricultural machinery, use mainly in machines cosechadoras, although also they mount in industrial fans, in manipulation of materials, in textile machinery, in machines of tools, as well as in machinery of production in the alimentary industry and of packs and packaging.

Schaeffler Has developed an exclusive system of obturación from 3 components —one covers external, lip obturador and one covers inner—, that increases the resistance of the threads, as well as the useful life of the machine.

These threads are easy to install and compensate the no ranged axles in a moment of clear-cut twist, decisive arguments that do that the engineers decide to use them. Because of the especially adverse conditions in that those that operate, the robustness, reliability and scarce maintenance of these threads, provide a decisive competitive advantage.
