SYG-4230 SYNTHETIC LONG-LIFE GREASE

Product Description

SYG- 4230 is high-speed grease with a good pressure absorption capacity. It consists of a combination of ester oil, synthetic hydrocarbon oil and barium complex soap. It offers good protection against wear and corrosion and is resistant to water, media and oxidation

Features and Benefits

  •            Tried and tested over many years especially in high-speed applications
  •            Excellent resistance to rust, erosion and oxidation.
  •            Extended re-lubrication intervals
  •            Synthetic long-term lubricating grease for a wide service temperature range.
  •             Longer component life due to optimized wear protection and good pressure absorption capacity
  •             Excellent resistance to water and media as well as above-average anticorrosive additives protect bearings against
  •             premature failure, thus helping to minimize repair costs
  •             Low intrinsic bearing heat due to low lubricant friction enabling longer service life

  •            Uninterrupted machine operation due to good pump ability and metering in customary centralized lubricating systems

Applications

SYG- 4230 is primarily used for spindle bearings and high-speed plain bearings, e.g. in machine tools and textile machines. Further applications are in threaded spindles, ball screws operating under high loads, running gear bearings, as a long-term grease in cableway bearings and in precision engineering. It may also be used for the lubrication of tooth flanks in precision gears (e.g. bevel gears in milling machines, electromechanical valve actuators).SYG-4230 ensures low starting and running torques
