| Tribol GR ALR 100-00 PDRobot GreaseDescriptionCastrol Tribol ® GR ALR 100-00 PD high-performance grease is based on fully synthetic base oil and a Lithium complexthickener system, enhanced with the MicroFlux Trans (MFT) additive system.Castrol's Microflux Trans (MFT) Plastic Deformation (PD) additive helps improve performance when operatingtemperature and loads reach a certain level of activation energy, by enabling the micro-smoothing of surface roughnesswithout increasing wear. The smoothed surface delivers optimum wear protection and an extremely low coefficient offriction, especially in applications which experience extreme pressure, shock loads, vibrations or low speeds. This helpswith extended lubricant life and prolong relubrication intervals.MFT PD helps to protect against scuffing and shock loading, while maintaining a high load carrying capacity, and canhelp prevent the progression of micro-pitting in pre-damaged gears.ApplicationTribol GR ALR 100-00 PD was developed for use in robot gear systems where grease lubrication is preferred overlubrication by gear oil. The combination of synthetic base fluid and lithium complex thickener system and the MFT-PDadditive system makes it particularly suited to a wide application temperature range.Low temperature performance is accurately measured for this type of flow grease by Rheometer measurement down to-40°C designed for easier start up at low temperatures (Also measured in the low temperature torque test).The MFT-PD additive system will help to maintain a stable backlash, which is required for high-precision robot-gears.Tribol GR ALR 100-00 PD has a base oil viscosity of 100 mm²/s and an NLGI grade of 00. This combination provides alower bleed rate than other commercially available greases avoiding oil leakages and a high base oil viscosity giving thegear box more protection.Tested with various elastomer seal material (95°C for 1008 hours), Tribol GR ALR 100-00 PD has excellent elastomercompatibility.AdvantagesCompared to other commercially available robot greases Tribol GR ALR 100-00 PD has the following advantages:MFT-PD technology shown to reduce wear, friction and protect gear surfaces.Very low friction torque levels particularly suited for start-stop motion in robots, including at low temperatures.Very low oil separation reducing the potential for leakage.Excellent elastomer compatibility to prevent seal damage.Extended lubrication life-time and relubrication intervals.Page: 1/2Typical CharacteristicsName Method Units Tribol GR ALR 100-00PDColour Visual - BrownThickener Type - - Lithium ComplexBase Oil - - SyntheticBase Oil Viscosity @ 40 °C / 104 °F ISO 3104 / ASTM D445 mm²/s 100Consistency ISO 2137 / ASTMD217NLGIGrade 00Worked Penetration (60 strokes @ 25°C / 77°F) ISO 2137 / ASTMD217 1/10 mm 400 - 430Worked Penetration - 100,000 strokes; change from 60strokes ISO 2137 / ASTM D217 1/10 mm +20Roll Stability test - Shear Stability (50 hrs, 60°C / 140°F) ASTM D1831 mod 1/10 mm +10Oil Separation (168 hrs @ 80°C / 176°F) ASTM D6184 mod % wt 20Evaporation Loss (24 hrs @ 100°C / 212°F) DIN 58397-1 % wt 1Oxidation Stability ASTM D942 psi 7Copper Corrosion (24 hrs,100°C / 212°F) ASTM D4048 rating 1aRheometer Dynamic Viscosity @ -20°C / -4°F in-house method Pa s 15Low Temperature Torque @-40°C / -40°F - Starting /Running Torque ASTM D1478 Nm 0.05 / 0.03Four Ball Weld Load test - Weld Point ISO 11008 / ASTMD2596 kgf 250+Four Ball Weld Load test - Last Non Seizure Load ISO 11008 / ASTMD2596 kgf 126Four Ball Weld Load test - Load Wear Index (27°C / 80°F /1770 rpm)ISO 11008 / ASTMD2596 kgf 56FE-8 Bearing Wear test (C/75/50) Rolling Elements(Mw50) DIN 51819-2 mg < 10FE-8 Bearing Wear test (C/75/50) Friction Torque DIN 51819-2 Nm 3Subject to usual manufacturing tolerancesTribol GR ALR 100-00 PD31 Oct 2022Castrol, the Castrol logo and related marks are trademarks of Castrol Limited, used under licence.This data sheet and the information it contains is believed to be accurate as of the date of printing.
