Our gear oils are designed to combat the effects of high temperatures, water, contaminants and heavy loads.
Sun chem gear oils are formulated with premium quality extreme pressure additive that is suitable for high loads and protects against wear. They are formulated with anti-foam, anti-rust and anti-wearing properties, they are each designed to ensure excellent performance under heavy and stressful loads and a wide variation of temperatures. These products are available in the iso viscosity grades: 10,15,22,32,46,68,100,150,220,320,460, 680
High-performance gear oil for industrial gearbox applications
Industrial gearboxes are expected to perform under conditions of high heat and heavy loads; and in environments often contaminated with dirt, process debris and water. Without adequate protection, gears will wear prematurely. You’ll have to replace parts more frequently, change oil more frequently, and worst of all, you’ll experience equipment downtime. To combat difficult conditions, sun chem offers an array of lubricants specially formulated for enclosed industrial gearbox applications.
Three essential attributes when selecting gear oil
Gear oil is made up of two critical components: base oil and additives. Additives impart desirable properties and suppress undesirable ones. The additive package is the backbone of the lubricant’s performance, and a strong backbone will provide the performance and protection you need. When selecting gear oil, there are three essential attributes to consider:
One - The gear oil must remain thermally stable and not oxidize at high temperatures, thus avoiding the creation of sludge or varnish. Keeping the oil from oxidizing will lengthen drain and replacement intervals. As a general rule of thumb, for every 18 degrees f (10 degrees c) increase in fluid temperature above 140°f (60°c), oxidation will reduce the service life of a lubricant by half.
Two – If you have an enclosed gearbox application that is heavily loaded or subject to shock loading, you need gear oil with extreme pressure properties. Gear oil with an ep additive will protect the gear surfaces against extreme pressures.
Three – Gear oil must fight contamination that enters the system, especially water. The oil must be able to demulsify, which allows for easy removal of the water from the gearbox.
