Overview

Klüber Klübersynth AR 34-402

Special synthetic lubricating greases for pneumatic drives and sealing elements

Application Klüber Klübersynth AR 34-402

Besides many other applications, Klübersynth AR 34-401 and -402 are mainly used for pneumatic control and sealing elements, such as ISO single-acting and double-acting pneumatic cylinders with and without piston rod, pneumatic rotary actuators, short-stroke and compact cylinders, for valves and corresponding sealing elements. Wide piston speed ranges from approx. 0.01 m/s to > 1 m/s can be achieved. Other advantages of Klübersynth AR 34 401 and -402 are low breakaway torque even after longer periods of standstill and reduced tendency to stick-slip at very low piston speeds. This special grease is preferably used in combination with various types of piston, rod and damping seals made of NBR or PU elastomer materials.

Product Description Klüber Klübersynth AR 34-402

Klübersynth AR 34-401 and -402 are synthetic wide-range greases based on a special calcium soap thickener. They are free from raw materials containing heavy metals and solid lubricants. The special additives contained in these greases provide utmost performance along with operational reliability and long service life. The pneumatic components consisting of the sealing elements and the opposing friction bodies, such as piston rods or cylinder barrels, can therefore be used in a relatively wide service temperature range. This is the result of a close cooperation between Klüber Lubrication, manufacturers of pneumatic elements and joints and university research centers. Klübersynth AR 34-401 is NSF H1 registered and therefore complies with FDA 21 CFR § 178.3570. The lubricant was developed for incidental contact with products and packaging materials in the food-processing, cosmetics, pharmaceutical or animal feed industries. The use of Klübersynth AR 34-401 can contribute to increase reliability of your production processes. We nevertheless recommend conducting an additional risk analysis, e.g. HACCP.

Application notes

Klübersynth AR 34-401 and -402 are applied by brush, sponge, spatula, grease gun or other conventional metering systems. For the lubrication of cylinder faces the use of round brushes or automatic greasing pistons has proven effective. It is important that after assembly the piston is moved several times over the full stroke length in order to ensure adequate wetting of the sealing elements on both sides if, for example, only one-sided lubrication was possible. A similar procedure applies to valves. Excessive lubrication of the piston seal after several piston strokes – depending on the size and circumference – may provide a more uniform grease layer. The lubricant should be applied on to a cleaned, grease-free surface.
