SC 51122 is a zinc-containing additive package for hydraulic oils, meticulously crafted to enhance the performance and
longevity of hydraulic systems across diverse applications. This specialized blend is engineered to provide superior
lubrication, protection, and efficiency to hydraulic components, ensuring smooth and reliable operation.
General Application
SC 51122 Zinc-containing Hydraulic Additive Package is renowned for its outstanding anti-wear and anti-oxidation
properties, making it suitable for a wide range of applications. Here are some common applications for zinc-containing
hydraulic oils:
- Industrial Machinery: Package Additive provide essential lubrication and protection for hydraulic components, such as pumps, valves, and cylinders, operating in these demanding environments.
- Construction Equipment: The oils with SC51122 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. Hydraulic oils with SC51122 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. Hydraulic oils with SC51120 help reduce wear and maintain system performance, even in the abrasive and challenging conditions of mining operations.
- General Manufacturing: In addition to specific industries, hydraulic oils with SC51122 can also be used in various manufacturing and processing applications where hydraulic equipment is employed.



Features / Benefits
- Anti-Wear Protection: SC 51122 is well-known for its exceptional anti-wear properties. It forms a protective film on metal surfaces, reducing friction and preventing metal-to-metal contact. This results in extended component life and reduced wear and tear on hydraulic system parts.
- Oxidation Resistance: This resistance to oxidation ensures that the oil maintains its properties and lubricating capabilities, even under high-temperature conditions.
- Corrosion Protection: SC 51122 provides effective corrosion protection to hydraulic system components. This is particularly 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, these oils contribute to increased system reliability and reduced downtime for maintenance and repairs. This can result in cost savings for businesses.
- Compatibility: They are typically compatible with various hydraulic system materials and seal types. However, it's essential to check compatibility with specific materials and seals to ensure there are no adverse reactions.
- Protection Under High Pressure: SC 51122 is effective at maintaining its protective properties even under high-pressure conditions, ensuring the longevity of hydraulic systems in demanding applications.
- Demulsibility: They include demulsifying agents that help separate water from the oil, ensuring that the gear lubricant remains effective even in wet conditions.
