Trans Gipoid LS




 

Application

TNK Trans Gipoid LS series of gear oils is developed for lubrication of all types of hypoid gears of drive axles of cars, cargo trucks, buses, agricultural and construction machinery including those with self-blocking differentials (limited slip differentials).

Attention! TNK Trans Gipoid is not recommended for application in mechanical gearboxes with synchronizers made of non-ferrous metal alloys.

MINERAL Gear OIL

 

TNK Trans Gipoid LS is produced on the high-quality mineral base with addition of cutting-edge additive package providing excellent wear-protective properties and thermal oxidative stability, which allows achieving a long-life oil performance.

TNK Trans Gipoid LS series contains high-quality LS-Limited Slip additives ensuring quiet and soft operation of self-blocking differentials.

Due to specially selected composition of additives, TNK Trans Gipoid LS oils are multi-purpose oils, which can be applied in transfer gearboxes and other gears not equipped with limited slip differentials, where API GL-5 (GOST TM-5) oils are required. TNK Trans Gipoid series oils are developed in full conformity with requirements of domestic and foreign producers of hypoid gears for light cars and cargo trucks. These oils can be applied in gearboxes and other gears where API GL-5 oils are required.

ABOUT LIMITED SLIP SERIES OF OILS

Principle of operation of limited slip differential (otherwise called self-blocking differential) allows rotating wheels at varied rotational speed and simultaneously blocking them and transferring torsion torque from engine to both rear wheels (or front wheels in case of front-drive cars). This prevents wheel slip, enhances vehicle maneuverability and controllability when moving on different road surfaces.For trouble-free operation of self-blocking differentials, special transmission oils are required, which are similar to GL-5 oils but have additional characteristics. Oils for self-blocking differentials are distinguished from traditional oils for rear axles by special package of additives, which enhances lubricating quality. These oils withstand severe loads, which are normal for limited slip differentials.

ADVANTAGES

TNK Trans Gipoid series have the following advantages:

  • Specially developed package of antiscoring additives provides high level of protection at extreme impact loads typical for operation of self-blocking differentials
  • Long oil life and enhanced antioxygenic and wear-protective properties increase the transmission operational life thus avoiding equipment downtimes
  • Developed in full conformity with requirements of domestic and foreign producers of hypoid gears both for cargo trucks and cars
  •  A wide range of viscosity levels allows choosing oil which protects all components of any transmission at any ambient temperature.

Approvals and compliances

  • SAE 90, 80W-90 and 85W-140 viscosity grades
  • API GL-5 operation class (oils for drive axles with hypoid gears operating under the conditions of high-speed impact loads and low-speed loads with high transfer torque).
  • TNK Trans Gipoid series complies with requirements ZF TE ML 05C/12C/16E, MAN 342 N-1

PACKAGING

Oil is supplied in 20 l cans, 180 kg barrels as well as in bulk by car and railway transport
