Klüber Petamo GHY 441 High-temperature lubrication grease 25kg

High-temperature and long-term lubricant for rolling bearings subject to high loadsPETAMO GHY 443 and PETAMO GHY 441 (recommended for relubrication due to its softer consistency) are special lubricating greases based on ester oil and polyurea thickener.The greases have been especially designed for the lubrication of rolling and plain bearings subject to high loads and temperatures. Being an efficient alternative to mineral oil based products, PETAMO GHY 443 and PETAMO GHY 441 achieve a much longer service life and therefore help to reduce maintenance costs. Due to their high base oil viscosity and excellent thermal stability they are mainly used for large rolling bearings.Content: 25kg bucketAvailable in 400g cartridge, 1kg can, 25kg bucketBenefits for your applicationTried-and-tested grease for long-term lubrication, less maintenance and high reliabilityGood load-carrying capacity prevents wear, hence longer bearing lifeExcellent water resistance and corrosion protection prevent premature bearing failure and help to reduce maintenance costsReduction in grease consumption and high resistance to oxidation and ageing due to the synthetic grease formulationApplicationFor the initial and relubrication of rolling and plain bearings subject to high temperatures in general machinery, electric motors, load rollers in conveyors, roller bearings and continuous wood panel presses, load rollers in continuous casting machines and many other applications.Application notesThe greases can be applied by spatula, brush, grease gun or via centralized lubrication systems (PETAMO GHY 441). Prior to initial application please check compatibility with current greases and pre-clean bearings, where necessary.Product data Lower service temperature -30 °C / -22 °F Upper service temperature 180 °C / 356 °F Color space beige Texture fibrous Texture homogeneous Density at 20 °C approx. 0.97 g/cm³ Worked penetration, DIN ISO 2137, 25 °C, lower limit value 310 x 0.1 mm Worked penetration, DIN ISO 2137, 25 °C, upper limit value 340 x 0.1 mm Kinematic viscosity of the base oil, DIN 51562 pt. 01/ASTM D-445/ASTM D 7042, 40 °C approx. 440 mm²/s Kinematic viscosity of the base oil, DIN 51562 pt. 01/ASTM D-445/ASTM D 7042, 100 °C approx. 36 mm²/s Corrosion inhibiting properties of lubricating greases, DIN 51802, (SKFEMCOR), test duration: 1 week, distilled water <= 1 corrosion degree Corrosion inhibiting properties of lubricating greases, DIN 51802, (SKFEMCOR), test duration: 1 week, distilled water <= 1 corrosion degree Flow pressure of lubricating greases, DIN 51805, test temperature: -30 °C <= 1 400 mbar Drop point, DIN ISO 2176 >= 250 °C Speed factor (n x dm) approx. 250 000 mm/min Minimum shelf life from the date of manufacture – in a dry, frost-free place and in the unopened original container, approx. 24 months Information on product safety (Manufacturer, Contact)KLÜBER LUBRICATION MÜNCHEN GMBH & CO.
