Transmission oil RENA Hypo Guard 85W-140
Transmission oil RENA Hypo Guard 85W-140
Extra-thick 85W-140 transmission oil for differentials with ultra-high pressures. Effectively compensates for operational wear.
The operation of construction or agricultural machinery with colossal loads inevitably causes extreme pressures in gear drives and the risk of overheating axles. RENA Hypo Guard 85W-140 is an extra-thick GL-5 standard transmission oil designed for stable gear protection under boundary friction conditions. Its dense polymer film does not tear, providing reliable protection against scuffing and breakdowns. Furthermore, the high viscosity perfectly compensates for increased clearances in worn equipment, eliminating extraneous noises. Contact our manager to place an order or discuss partnership terms.
High-viscosity transmission oil of SAE 85W-140 class. Kinematic viscosity at 100°C is 28.2 mm²/s, index 90. Pour point -12°C. Strong thermal stability is confirmed by a flash point of 220°C. Weld load 3685 N. Meets API GL-5.
