SC 51101 is a zinc-containing additive package for hydraulic oils, meticulously designed to enhance the performance
and longevity of hydraulic systems across diverse applications. This specialized blend delivers superior lubrication,
protection, and efficiency to hydraulic components, ensuring smooth and reliable operation.
General Application
SC 51101 Zinc-Containing Hydraulic Additive Package is renowned for its excellent anti-wear and anti-oxidation
properties, making it suitable for various applications. Here are some common uses for zinc-content hydraulic oils:
- Industrial Machinery: Zinc-based hydraulic oils are widely used in industrial machinery, including hydraulic presses, manufacturing equipment, and metalworking machines. They provide essential lubrication and protection for hydraulic components such as pumps, valves, and cylinders in these demanding environments.
- Construction Equipment: Hydraulic systems in construction machinery, such as excavators, bulldozers, and cranes, benefit from zinc-containing hydraulic oils. These oils ensure smooth operation and help extend the service life of hydraulic components subjected to heavy loads and harsh conditions.
- Agricultural Machinery: Tractors, combine harvesters, and other agricultural equipment often rely on hydraulic systems for functions like lifting, tilting, and steering. Zinc-based hydraulic oils provide the necessary lubrication and wear protection for these systems in the agricultural sector.
- Mining Equipment: In the mining industry, hydraulic systems are used in drilling rigs, loaders, and haul trucks. Zinccontaining hydraulic oils help reduce wear and maintain system performance, even in the abrasive and challenging conditions of mining operations.
- Forestry Equipment: Hydraulic systems in forestry machinery, such as log loaders and tree harvesters, require reliable lubrication and protection. Zinc-based hydraulic oils ensure these systems can operate effectively in rugged forestry environments
- Marine Applications: Hydraulic systems on ships and boats, including those used for steering, winches, and deck machinery, benefit from zinc-containing hydraulic oils. They provide corrosion resistance and anti-wear protection in maritime environments.
- Automotive and Racing: Some high-performance and racing vehicles use zinc-based engine oils to protect critical engine components, such as camshafts and lifters, from wear and friction. While this is different from hydraulic oils, it still involves zinc-containing lubricants.
- General Manufacturing: In addition to specific industries, zinc-containing hydraulic oils can also be used in various manufacturing and processing applications where hydraulic equipment is employed.







Features / Benefits
- Anti-Wear Protection: SC 51101 is renowned for its exceptional anti-wear properties. It forms a protective film on metal surfaces, reducing friction and preventing metal-to-metal contact. This extends component life and reduces wear and tear on hydraulic system parts.
- Oxidation Resistance: SC 51101 exhibits resistance to oxidation, ensuring that the oil maintains its properties and lubricating capabilities, even under high-temperature conditions.
- Corrosion Protection: SC 51101 provides effective corrosion protection to hydraulic system components. This is especially important in environments where moisture and corrosive substances may be present, such as marine and industrial settings
- Reduced Downtime: By minimizing wear on critical hydraulic components, SC 51101 contributes to increased system reliability and reduced downtime for maintenance and repairs, resulting in cost savings for businesses.
- Improved Efficiency: Lower friction and reduced wear within the hydraulic system can lead to improved overall efficiency.
- Compatibility: SC 51101 is typically compatible with various hydraulic system materials and seal types. However, it is essential to check compatibility with specific materials and seals to ensure there are no adverse reactions.
- Extended Fluid Life: The anti-oxidation properties of SC 51101 can extend the useful life of hydraulic fluid, reducing the frequency of fluid changes and associated maintenance costs.
- Protection Under High Pressure: SC 51101 maintains its protective properties even under high-pressure conditions, ensuring the longevity of hydraulic systems in demanding applications.
- Demulsibility: SC 51101 includes demulsifying agents that help separate water from the oil, ensuring that the gear lubricant remains effective even in wet conditions.
