Transmission oil RENA Synchro Guard 85W-140


Transmission oil RENA Synchro Guard 85W-140
Extra-thick 85W-140 transmission oil to protect gears at ultra-high pressures. Resistant to thermal degradation.
The operation of large-sized commercial and construction equipment is associated with colossal loads on gear drives and a high risk of overheating. RENA Synchro Guard 85W-140 is an extra-thick semi-synthetic oil created specifically to protect mechanisms at extreme pressures and high summer temperatures. Its strong polymer structure does not tear, guaranteeing reliable protection against breakdowns and scuffing. The oil successfully compensates for increased clearances, significantly reducing mechanical vibrations. To place an order or discuss partnership terms, please call our manager.
High-viscosity transmission oil of SAE 85W-140 class. Kinematic viscosity 28.2 mm²/s at 100°C. Pour point -12°C. Protection under maximum thermal loads is confirmed by a flash point of 220°C. Meets API GL-4.
