Hypoid gear oil
Properties
Astron Gear Oil 85W-140 GL 5 is made from carefully chosen base oils and additives that prevent tooth flank damage. The EP additives contained in the gear oil form a load-bearing lubricant film between the tooth flanks when the gears intermesh. It therefore prevents scoring even under extreme mechanical loads and significantly reduces abrasion wear. The gear oil is extremely ageing resistant, even under high thermal load. The good low-temperature viscosity is achieved through the high degree of refining of the base oil and the added flow improver. The gear oil contains highly effective active agents that suppress foaming and protect the lubricated machine parts against damage from corrosion.
Astron Gear Oil 85W-140 GL 5 does not cause damage to conventional sealing materials.
Use instructions
Astron Gear Oil 85W-140 GL 5 is primarily recommended for heavy-duty drive axle systems with hypoid gearing in commercial vehicles.
