Description
Special synthetic lubricating greases for pneumatic drives and sealing elements
- 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. - Content: 25kg bucket
- Available in 1kg can, 25kg bucket
Benefits for your application
- Reduces friction and wear in pneumatic components
- Low breakaway torque, even after longer periods of standstill (“Monday morning effect”)
- Suitable for all types of pneumatic components, preferably those made of NBR but also of PU materials
- Wide piston speed range from approx. 0.01 to 1m/s and much more in individual cases
- Light colour, adhesive
Application
- 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. Klübersynth AR 34-402 is an approved lubricant for gas burning installations and actuators acc. to DIN EN 377 class D, for a temperature range from 0 to +140°C. A corresponding DIN-DVGW test certificate is available.
