Textile Bearings Texparts® Bearing Units For intelligent movement Exact guiding and supporting of machine elements is one of the standard design requirements of mechanical engineering. The key to success, however, is to design the bearing so that the special requirements of the textile industry are met. Particularly in the textile industry - with a lot of dust and fibre fly - it is of utmost importance to seal the bearings, requiring special solutions. But also the high variations in temperature in textile mills make very high demands on the bearings. The target of Oerlikon Textile Components mechanical engineers is to design elements which are fulfils following requirements: • Maximum friction reduction • Lowest vibration • Absolute low maintenance demands • Highest resistant to soiling • Highest resistant to temperature • With easily installable design Due to this design targets the customers having a product in there hands which offers them following advantages: • Maximum energy saving • Supporting high quality of the textile product • Low noise level • Low maintenance cost • Long service life Oerlikon Textile Components has a team of highly qualified and experienced experts, who develop bearings for individual applications as well as for mass-market applications. The

competence of Oerlikon Textile Components consists in the combination of classical mechanical engineering and textile technology, i.e. the application and its needs. The Oerlikon Textile Components experts know the interactions between the textile machine and the textile product. Oerlikon Textile Components provides advice for mechanical engineers and end users in the textile industry concerning the efficient development or application of bearing assemblies in the textile manufacturing process. The Texparts® Bearings are subdivided into 3 main areas: • Bearings for ring spinning • Bearings for rotor spinning • Bearings for any other application in the textile industry

Each application area has its special demands on bearing technology. According to the variety of loads to be expected and the installationdepending facts of the textile machine, the bearing assemblies are designed with needle bearings, roller bearings or with integrated and discrete ball bearings. The lubrication system and the bearing seals are always adapted to the special application case.


Texparts® Bearings for Ring Spinning Texparts® Top Roller LP The quality of top rollers used in the spinning process - for back, front or apron rollers - is of vital importance for the quality of the produced yarn. Because of the direct contact of the top rollers to the roving drafting results and therewith the achieved yarn quality are influenced by the running behavior of the top rollers. Oerlikon Textile Components Product Portfolio includes 2 Series: • Texparts® LP 1200 Series • Texparts® LP 1000 Series Texparts® Top Roller LP 1200 Series

Texparts® Bearings for Rotor Spinning and General Application Texparts® Bearings TL Texparts® TL Rotor Bearings for direct driven open end machines are integrated bearing units with highest requirements concerning the accuracy of manufacture. The bearing raceways are ground in directly into the shaft and the bearing housing. The choice of a premium rotor bearing allow higher rotor speeds and a increase of the production of manual or semiautomatic rotor spinning machines. Texparts® TL Bearing Units offering the right solution to upgrade a mid-tier to a high-tier rotor spinning machine. The silent and equal running behaviour of the rotor bearing has an essential influence on the yarn evenness. Portfolio Maximum rotor speed (rpm)
