Bio Food Grade Gear Oil - ISO 320
Performance Specifications Test Descriptions
United Bio Lube is offering Brand Protection to Original Equipment Manufacturers (OEMs), Processing Plants that are seeking advanced sanitary, safety, and high performance features for their processing equipment.
United Bio Lube's Bio Food Grade1 EP Gear Oils meet and exceed Military Specifications DOD-L24651, "Lubricating Oils, Food Grade, and Food Processing Equipment", in addition to the food and drug industry's FDA, USDA H-1, and National Sanitation Foundation safety standards - while protecting capital investments in advanced processing and packaging equipment.
Gear Wear Protection
High load conditions, created from increased horsepower and torque, lead to accelerated wear in gear systems. Bio Food Grade Gear Oil - ISO 320 is engineered to protect Enclosed gear drives operating under high loads against wear, scoring, spalling and pitting.
Protection against wear is achieved by combining the high Fluid Film Strength, Oxidation Stability, Shear Stability, Heat Stability, and Load Carrying Capacity of Stabilized HOBS with advanced Anti-Wear and Extreme Pressure additives. Extreme Pressure and Anti-Wear additives protect metal surfaces with a Full Fluid Film designed to prevent metal-to-metal contact.
Bio Food Grade Gear Oil - ISO 320 is engineered to maintain separation between mating surfaces in Enclosed gear drives operating under high loads, shock-loading, and varying temperatures.
Several test methods are used to measure the Anti-Wear and Extreme Pressure properties of United Bio Lube's Bio Food Grade Gear Oil - ISO 320:
ASTM D 2782, "Four Ball EP (Extreme Pressure) Test", ASTM International.
The Load Wear Index measures the Bio Food Grade Gear Oil - ISO 320 ability to prevent wear at applied load.
Weld Point is the lowest applied load at which the sliding surfaces of four steel balls seize and weld together.
In the Four Ball EP Wear test method, four steel balls of the same size and metallurgy are used. Three steel balls, which are immersed in the Bio Gear Oil being tested, are locked into a test cup. A fourth steel ball that is held in place in a rotating chuck is placed on top of the three steel balls locked in the test cup.
The fourth steel ball is rotated at a speed of 1,770 rpm and subjected to a series of 10-second durations at increasing loads until welding of the steel balls occurs.
United Bio Lube's Bio Gear Oil - ISO 320 provides a high level of wear protection against Galling and Welding in heavily loaded gears as measured by a EP Weld Point of 160-200 kg.
ASTM D 4172, "Four Ball Wear Test", ASTM International.
The Four Ball Wear test method evaluates wear-preventing properties of Bio Food Grade Gear Oil - ISO 320 in steel-on-steel sliding conditions. This test is not intended to predict wear characteristics with other metal combinations other than steel-on-steel and does not measure the extreme pressure characteristics of the gear oil.
United Bio Lube's Bio Gear Oil's high level of wear protection under sliding conditions is measured by lower scar diameters.
Application Note: When comparing the capabilities of Bio Food Grade Gear Oil - ISO 320, both results obtained in the ASTM D 2782 Four Ball EP Test and the ASTM D 4172 Four Ball Wear Test should be considered. In some cases, petroleum based gear oils claiming to have good extreme pressure properties may not be effective in reducing wear rates at lower loads.
ASTM D 5182, DIN 51354, "Evaluating the Scuffing Load Capacity of Oils (FZG Visual Method)", ASTM International.
The Forschungstelle fr Zhnrder und Getriebebau (Research Site for Gears and Transmissions) Visual Method, commonly referred to as the FZG Visual Method, is intended to measure the Scuffing Load Capacity of oils used to lubricate hardened steel gears. Scoring, a form of abrasive wear, is also included as a failure criteria in this test method. It is primarily used to assess the resistance to scuffing of mild additive treated oils such as industrial gear oils, transmission fluids, and hydraulic fluids.
"FZG Visual Method" test method is used to evaluate the Anti-Scoring and Scuffing Load Capacity of Bio Food Grade Gear Oil - ISO 320. The FZG gear set simulates a misaligned gear set operating in a bath of lubricant.
The stage at which more than 20 percent of the load-carrying flank area of the pinion is damaged by scratches and/or scuffing is considered to be the failure load. The higher the load stages, the better the Bio Gear Oil's resistance to scuffing.
Extreme Pressure/Anti-Wear additives exceed a 'Load Stage' of 11 in the FZG visual method requirements for both turbine oils and reduction gears.
ASTM D 2782, "Timken Extreme Pressure Test", ASTM International.
The Timken Extreme Pressure test method is used to measure Abrasion Resistance and Load Carrying Capabilities of Bio Food Grade Gear Oil - ISO 320. The test method is widely used for specification purposes and to differentiate Bio Food Grade Gear Oil - ISO 320 that have Low, Medium, and High levels of Extreme Pressure characteristics.
The OK load is the last load before scoring has occurred. An Extreme Pressure Bio Gear Oil is considered to have good extreme pressure properties if it has a Timken OK load of at least 60 lb.
United Bio Lube's Bio EP Gear Oils exceed this specification with a Timken OK Loads of 33/35 lb.
Demulsibility Characteristics
Note: Water contamination of gear oils causes poor lubrication, corrosion, and accelerated rates of oxidation of the gear oil.
United Bio Lube's Bio Food Grade Gear Oil - ISO 320 resists mixing and emulsification with water by pooling together micro-droplets of water and precipitating this water into larger droplets that fall out of the system.
Bio Food Grade Gear Oil - ISO 320 separates readily from water. Demulsifiers work in two stages to prevent emulsification and enhance water separation. First, demulisification agents Flocculate the water droplets into bubbles by forming chemical bonds between water droplets. Demulsifier molecules, absorbed on the droplet's sheath, amplify chemical attractions between water molecules, forcing them together.
In the second stage, water molecules Coalescence, or merge into larger water droplets. Demulsifiers penetrate the emulsified film to form a channel through which water drains from one droplet to the other.
Both of these mechanisms allow small, stable water bubbles to combine into larger bubbles that sink to the bottom of the gear box to be drained off.
ASTM D 2711, "Demulsibility Characteristics of Lubricating Oils", ASTM International.
The "Demulsibility Characteristics of Lubricating Oils" test method is used to evaluate Bio Gear Oil's abilities to resist emulsification and to separate readily from moisture.
The test is primarily used to test the ability of medium and heavy viscosity (ISO 320 to ISO 3200) gear oils to separate from water.
ASTM D 1401, "Turbine Oil Demulsibility", ASTM International.
Lower range vicosities (ISO 30 to ISO 320) gear oils show excellent performance in Turbine Oil Demulsibility test method with a rating of 40/40/0 in 10 minutes.
Rust and Corrosion Protection
There are many types of industrial gear drives that have parts made of copper, brass or bronze. In addition to being non-corrosive to yellow metals, Bio Food Grade Gear Oil - ISO 320 prevent rusting of ferrous metal components.
Bio Food Grade Gear Oil - ISO 320 is highly inhibited against moisture and rusting in both fresh and sea water environments. This is demonstrated in 'Passing" results of both A and B Sequences of the ASTM D 665, "Turbine Oil Rust Test".
United Bio Lube's Bio Food Grade Gear Oil - ISO 320 is fortified with advanced Bio Corrosion Inhibitor (BCI™) technology. BCI technology is not chemically reactive to yellow metal containing parts as demonstrated by the ASTM D 130, "Copper Strip Corrosion Test".
ASTM D 130, "Copper Strip Corrosion Test", ASTM International.
The Copper Strip Corrosion test method is used to evaluate the corrosive tendencies of Bio Food Grade Gear Oil - ISO 320 on copper containing materials.
Gear Oils exhibiting a 1B classification in this test are considered to exhibit good resistance corrosion to yellow metals.
United Bio Lube's Bio Food Grade Gear Oil - ISO 320 exceeds this specification with the highest rating of 1A.
ASTM D 6654, "Turbine Oil Rust Test", ASTM International.
The Turbine Oil Rust test method measures United Bio Lube's Bio Gear Oil's ability to prevent rusting under conditions of water contamination. The test consists of two parts. Part A uses distilled water, and Part B uses synthetic seawater.
To pass the ASTM D 665 test, the specimen must be completely free from visible rust when examined without magnification under normal light.
United Bio Lube's Bio Food Grade Gear Oil - ISO 320 exceeds this criterion, passing both part A and part B with the highest ratings.
Rust and corrosion inhibiting properties are further enhanced by a very high resistance to Oxidation and 'Thermal' breakdown.
United Bio Lube's Bio Food Grade Gear Oil - ISO 320 provides double the Oxidation Stability over the US Steel 127 test requirement of 125 minutes.
Resistance Against Foaming
All industrial gear drives are exposed to airflow. The churning action of gears and bearings through gear oil can cause air entrainment or foaming, especially in high speed gear sets.
United Bio Lube's Bio Gear Oil - ISO 320 prevents the following problems due to Foaming:
|
- Increased machine operating temperatures.
- Inadequate lubrication due to reduced oil flow.
- Loss of oil film between mating surfaces of gears.
- Spongy and erratic operation.
- Loss of the gear lubricant due to overflow.
- Increased oxidation of gear oil.
- Increased gear and bearing noise.
- Cavitation and Erosion.
