Precision Lubrication for High-Stress Environments: The Case for Flexislip 68 Extra Quality

Viscosity

| Feature | Standard Hydraulic Oil (HLP 46) | Flexislip 68 Extra Quality | | :--- | :--- | :--- | | | Thinner (flows faster) | Thicker (flows slower) | | Primary Purpose | Power transmission | Friction reduction & Surface protection | | Adhesion | Low (drips easily) | High (clings to surfaces) | | Stick-Slip Control | Poor | Excellent | | Film Strength | Moderate | High (due to tackifiers) |

Additives:

Includes anti-wear, anti-rust, and anti-oxidation agents to extend machinery life and protect against corrosion. flexislip 68 extra quality

• Group II or Group III base oils (low sulfur, high saturation) for thermal/oxidative stability.
• Zinc dialkyldithiophosphate (ZDDP) – primary anti-wear agent (forms protective film under boundary lubrication).
• Phenolic & aminic antioxidants – extend oil life, reduce sludge.
• Corrosion inhibitors – protect ferrous and yellow metals.
• Demulsifier – promotes rapid water shedding.
• Antifoam agents (silicone or non-silicone).
• Metal deactivators – to prevent catalytic oxidation from copper.

What is Flexislip 68 Extra Quality?

At its core, Flexislip 68 Extra Quality is a premium R&O (Rust and Oxidation inhibited) industrial gear oil, graded at ISO VG 68. However, the "Extra Quality" designation isn't just marketing jargon. It signifies that this oil surpasses standard industry specifications for thermal stability and demulsibility. Group II or Group III base oils (low

While the initial cost per liter may exceed standard oils, the total cost of ownership (TCO) typically decreases due to: What is Flexislip 68 Extra Quality

Superior Stick-Slip Prevention

: Specially formulated to eliminate the "stick-slip" effect, ensuring smooth and precise movement of machine tool carriages even at low speeds and under high loads.

If you need exact OEM approvals (e.g., Bosch Rexroth, Denison, Vickers), request the product datasheet.

Thermal Stability:

Typically has a high flash point of approximately 232°C and a low pour point around -28°C , allowing for reliable operation across various temperature ranges.
