KLUBERSYNTH 50 KV

Synthetic high-performance gear oils for weaving machines.

In modern weaving machines, high-performance gear oils are expected to enable longer maintenance intervals at high production speeds.

It is with this trend in mind that we developed our Klübersynth 50 KV, 80 KV and 100 KV oils. These are synthetic high-performance gear oils based on polyglycol. They are resistant to ageing, protect reliably against wear and offer an excellent load-carrying capacity as well as viscosity-temperature behaviour. With Klübersynth 50 KV, 80 KV and 100 KV oils, oil change intervals of up to 20,000 operating hours are realistic, which can lead to considerably lower operating costs.

Klübersynth 50 KV, 80 KV and 100 KV are exclusively recommended by the Italian textile machine OEM ITEMA for the lubrication of gears, bearings and other sliding friction points in Leonardo-type weaving machines. For Leonardo-type weaving machines with oil coolers,
ITEMA recommends Klübersynth 50 KV, and for the R 9500-type machines Klübersynth 80 KV.
Klübersynth 50 KV, 80 KV and 100 KV oils can be applied by immersion, immersion circulation or injection. When using automatic lubricating systems, please note the manufacturer's instructions regarding the maximum permissible viscosity. Klübersynth 50 KV, 80 KV and 100 KV oils are not miscible with mineral oil or synthetic hydrocarbons. Prior to changeover, we recommend cleaning the lubrication points or rinsing the gears or enclosed lubrication systems with Klübersynth 50 KV, 80 KV or 100 KV.
Klübersynth 50 KV, 80 KV and 100 KV oils are neutral towards ferrous metals and almost all nonferrous metals. There may be increased wear when the contact surfaces of design elements made of aluminium or aluminium alloys are exposed to dynamic loads. If necessary, preliminary wear tests should be carried out. Depending on the temperature and time of exposure, synthetic lubricants based on polyglycol can affect the function of rubber-elastic sealing materials. For permanent temperatures up to 100 °C (corresponds to the temperature limit of Klübersynth 50 KV, 80 KV and 100 KV), seals made of NBR (butadiene-acrylonitrile rubber) can be used. It should be noted that elastomers from one or several manufacturers can behave differently.
When applying Klübersynth 50 KV, 80 KV and 100 KV oils, we recommend the use of two-component paints (reaction paints) for interior coating. Oil gauge glasses should preferably be made of natural glass or polyamide materials. Other transparent plastics, e.g.
Plexiglas, have a tendency to crack under stress. We recommend to check compatibility of the materials with the lubricant used, especially prior to series application.

Specially recommended for Leonardo weaving machines from ITEMA. With Klübersynth 50 KV, 80KV 100 KV oils, these weaving machines reach optimum service life. Oil change only every 20,000 operating hours.
Cost reduction due to the very good friction behavior of the polyglycol base oil, which reduces power losses and increases efficiency.
Reduced maintenance costs due to high friction load resistance and good anti-wear effect adequately protect gears and other lubricated components against friction even at high peak loads.
The excellent viscosity-temperature behavior ensures higher operating reliability thanks to sufficient parts lubrication even at high or elevated machine temperatures.
