Customer Benefits
Corrosion Delo Gear EP-4 delivers value through:
- Long gear life
Extreme pressure properties protect hypoid and other types of gears from scuffing and wear. - Rust and corrosion protection
Effective inhibitor package protects against rusting or corrosion of gear and bearing surfaces. - Excellent foam inhibition
Foaming minimized by use of foam inhibitor. - Long lubricant life
Outstanding thermal and oxidation stability allow high temperature operation with long lubricant life. - Seal Protection
Formulated to protect against oil seal deterioration.
Product features
- The sulfur-phosphorus extreme pressure additive technology used in Delo Gear EP-4 provides exceptional thermal and oxidation stability. In addition, this lubricant is fortified with rust and corrosion inhibitors, a foam inhibitor, and a pour point depressant
- Delo Gear EP-4 minimizes the spalling and wear of gears by creating a microthin sacrificial film on the surface of the gear teeth which is actually softer than the gears themselves. Frictional heat and pressures between gear teeth cause the sulfur-phosphorus to react with the surfaces of the gear teeth at the point of contact, thus creating the sacrificial film. The highly refined base stocks and various inhibitors in the additive package help assure a well balanced lubricant and long gear and bearing life.
Applications
Delo Gear EP-4 are recommended for use in spiral bevel and hypoid differentials, power dividers, and oillubricated steering axle wheel bearings.
