• Is the grease able to prevent corrosion? Get it as soon as Thu, Mar 4. The lack of compatibility shows up as grease thinning. Before converting major systems to a new grease, exhaustive testing may be warranted to prevent significant cost and time delay due to long-term maintenance problems. Lansdown, A. (1994). In these two cases, the selection criteria differ appreciably. Areas of application Gearbox lubrication of heavily loaded, relatively slow-running toothed gearing when grease is used instead of oil due to leaks Multiuse greases are required in a variety of different applications, many having different performance challenges. FREE Shipping on orders over $25 shipped by Amazon. High Performance Multiuse (HPM) Grease Specifications • Final specifications have been approved by NLGI Board • Performance -based specification: • Range of NLGI grades (#1 to #3) to allow for needs of application • Performance is key: • Is the grease capable of supporting high loads? The R0F and R0F+ tests determine the grease life and its high temperature performance limit (HTPL). Mystik High-Temperature lithium complex Grease certified GC-LB by the National Lubricating Grease Institute (NLGI) for automotive wheel bearings and chassis; Provides excellent protection in severe service requirements such as disc brake wheel bearings, backhoe hinge pins, and conveyor bearings If the manufacturer makes a particular type of synthetic base fluid and is intimately familiar with the various destruction mechanisms of that fluid, then it is likely that this type of synthetic base will often be selected for new product development. Table 2 includes some of these options. 2. hbspt.cta.load(3951034, '0185d019-b885-48b3-81bb-598c6269bb64', {}); The American Petroleum Institute divides base oils into five categories that are useful in initially selecting base oil by performance limits. Additionally, there are polar products that remain in the Group I base oils called heterocycles (nitrogen, sulfur and oxygen- containing molecules). Buy RS PRO High Temperature Grease 50 ml Tube . Synthetic Grease For Extreme High Temperatures. High Temperature Lubrication. Some clay-thickened (bentonite) greases may similarly have very high melting points, with dropping points noted on the product data sheets as 500ºC or greater. The operating temperature may be less than what it seems. Read about company. L-80 has a continuous temperature operating range of -20 centigrade to +260 centigrade and an intermittent or short term use upto 240 centigrade. A dropping point over 500°F because it contains a lithium complex thickener PEAK® High-Temperature Red Lithium Grease is available in three sizes – a 14 oz. Dow Corning High-Vacuum Grease is recommended for vacuums reaching between 1 x 10-5 and 1 x 10-6 mm Hg. Greases could be divided by temperatures along the lines in Table 1. If it is continuous - constant 392ºF (200ºC) or greater - then go with the higher-tier product after appropriate testing. Is it intermittent or continuous? Lansdown, A. Lubrication and Lubricant Selection: A Practical Guide. p. 102. If it is continuous, then look for a top-tier product that meets the operational requirements. 6 However, unless the grease composition is properly fortified against oxidation and thermal degradation, the end product showing a dropping point of 500ºF (260ºC) or greater would not be any more useful for long-term service than a grease with a low dropping point. Automotive assemblers hang painted metal parts on long conveyors and weave them through large drying ovens to dry painted metal surfaces. High Temperature Lubrication. Free Next Day Delivery available. CONDAT high-temperature greases are formulated to resist high temperatures superior to 130°C. Polyurea thickeners might become more popular but they are difficult to manufacture, requiring the handling of several toxic materials. High Temperature Lubrication. Consider whether the application is intermittent or continuous high-temperature. 5. tub or 4 lb. hbspt.cta.load(3951034, 'c99217f3-09e7-4751-bc3a-7739dac44a0e', {}); Product Unboxing - Simalube Single-Point Automatic Lubricators, How to Calculate Grease Quantity and Frequency for Bearings, 7 Steps to Trouble-free Grease Lubrication, Unboxing: Luneta Column Sight Glass in Tritan™, Unboxing: Mystik® JT-9™ LeakShield® AW Hydraulic Oil, Product Unboxing: Hy-Pro Compact Offline Filter, The Cost Effective Benefits of a High Performance Kidney Loop System, 8 Steps to Successfully Implement a Preventive Maintenance Program. Because greases represent a complex mixture of chemicals with a well-defined and engineered balance, the addition of unplanned chemicals tends to upset the balance and degrade performance levels. The high temperature, high pressure grease from WD-40 is a lithium based grease built to perform in tough conditions. WD-40 SPECIALIST heavy-duty high temperature grease was engineered to meet the demands of protecting high-speed bearings in applications involving high temperatures and heavy mechanical loads. The grease’s long-term behavior is influenced by the causes of degradation, three of which are particularly important: mechanical (shear and stress) stability, oxidative stability and thermal stability. In addition to heat resistance, the grease to be used in a hot steel mill application may require exceptional load-carrying capability, oxidation stability, mechanical stability, water wash resistance and good pumpability, and at a price suitable for large-volume consumption. If the temperature is intermittent, then a middle-tier product may be equally useful with appropriately adjusted relubrication intervals. The additives tend to provide properties for greases in fashion similar to lubricating oils: oxidation stability, corrosion resistance, wear resistance, low temperature flow characteristics, water resistance, etc. Consider any cosmetic issues. Because oils, additives and bases will react at various rates, there is something good to be said about using simpler products.
