DEPA.TG68 Precision Rail Oil from China Suppliers - High Viscosity Multi-Purpose Hydraulic Lubricant from Factory
Advantages
- Very long service life.
- Excellent anti-scuffing property gives special protection even when high speed, high pressure and high temperature conditions are encountered.
- Excellent corrosion and rust prevention.
- Good demulsibility promotes quicker water separation. If water is an unavoidable contaminant, this advantage effectively retains lubrication.
- Anti-foam additive allows any entrained air to be released and burst quickly, ensuring enough lubrication between machine parts at any time.

Frequently Asked Questions
Q
What grades are available for this turbine gear oil?
This turbine gear oil is available in four viscosity grades: TG32, TG46, TG68, and TG100, each designed to meet different operating speed, load, and temperature requirements in industrial and power generation applications.
Q
How does the anti-scuffing property protect machinery under extreme conditions?
The oil's excellent anti-scuffing additives form a protective film on metal surfaces, preventing direct metal-to-metal contact even under high speed, high pressure, and elevated temperature conditions. This significantly reduces wear and extends the service life of gears and bearings.
Q
Why is good demulsibility important in turbine gear oil?
Good demulsibility allows the oil to separate from water quickly and efficiently. In environments where water contamination is unavoidable — such as steam turbines or humid industrial settings — rapid water separation ensures the lubricating film remains intact, protecting components from corrosion and wear.
Q
What is the significance of the high flash point values in these oils?
The flash points range from 215°C (TG32) to 260°C (TG68 and TG100), indicating a high resistance to ignition. This makes the oil safer to use in high-temperature industrial environments, reducing fire risk and ensuring stable performance under thermal stress.
Q
How does the anti-foam additive benefit machine operation?
The anti-foam additive enables entrained air bubbles to be released and collapsed rapidly. This prevents foam formation in the oil system, which could otherwise lead to oil starvation, cavitation, and inadequate lubrication between moving parts — all of which can cause premature component failure.
Q
Which viscosity grade should I choose for my application?
The right grade depends on your equipment's operating conditions. TG32 and TG46 are typically suited for lighter loads and higher speeds, while TG68 and TG100 are recommended for heavier-duty applications with higher loads and lower operating speeds. Always refer to your equipment manufacturer's specifications for the recommended viscosity grade.
