Main customer benefits
Years of probation The K-Ring has proven its worth in the pneumatic cylinder and valve range. Its use in your constructions does not involve any risk. Different versions Outer sealing and internal sealing Wide range of diameters from 6 to 406mm No tolerance problems When machining the pistons and running surfaces, installation tolerances c11 / H11 and larger are permissible. Low friction On average, only 2% of the available piston force is lost due to friction. Elaborate membrane constructions (eg in control devices) can often be replaced by K-rings. No sealing problems The K-ring ensures 100% tightness under vacuum and overpressure. Even with a pressure change on the sealing ring, no air losses occur. Easy lubrication The special design of the sealing edge allows the grease film on the tread to be preserved for a long time. Therefore, relubricating with mist oilers can be dispensed with in many cases. Suitable fats and oils are available on request. Normal pressure range from vacuum to 10 bar overpressure. K-rings for higher pressure on request. Long service life Depending on the stroke, several million switching cycles are possible. Quality Between - 20 ° C and + 100 ° C usable Perbunan normal quality. Resistant to water and all mineral oils without foreign additives. Further heat- and cold-resistant qualities on request. Treads Commercially available tubes and rods with a surface roughness of about 2μ may be used. Conicity and out-of-roundness are largely compensated by the K-ring.
