Unioil presents GEARLUBE, a premium gear oil developed to protect gear systems and support dependable performance under demanding operating conditions. Built around the promise of “Stronger gears, longer-lasting machines,” GEARLUBE is designed for applications where gears must withstand continuous pressure, heavy loads and sudden changes in operating conditions. With the right lubrication, equipment can maintain smoother operation while reducing the risk of premature wear caused by inadequate protection.
Meeting SAE 80W-90 viscosity grade and API GL-5 performance level, UNIOIL GEARLUBE is formulated for compatible gearboxes, hypoid axles and differentials that require extreme-pressure protection. These components play a critical role in transmitting power, and their gear teeth are exposed to substantial contact pressure during operation. Choosing a suitable gear oil helps maintain a protective film between contacting surfaces, supports reliable power transmission and contributes to longer equipment service life.
1. API GL-5 for Hypoid Gears and Differentials
UNIOIL GEARLUBE meets the API GL-5 performance level, which is intended for gear systems requiring enhanced protection under high-load conditions, including many hypoid gear applications. Hypoid gears are commonly found in vehicle axles and differentials, where their design allows power to be transferred between intersecting or offset shafts. During operation, the gear teeth experience a combination of sliding and rolling contact, creating demanding lubrication requirements.
Under heavy loads or sudden changes in torque, the contact surfaces can experience substantial pressure. GEARLUBE is designed to provide the extreme-pressure protection required by compatible GL-5 applications, helping protect gear teeth against excessive wear and surface damage. By selecting an oil that meets the equipment manufacturer’s specifications, users can support dependable drivetrain operation and help maintain the performance of critical transmission components.
2. Extreme-Pressure Protection Under Heavy Loads
Heavy-duty gear systems require more than basic lubrication. When gear teeth transmit high torque, the pressure concentrated at their contact points can challenge the oil film separating the metal surfaces. Without sufficient protection, repeated contact may contribute to scoring, scuffing, pitting and accelerated wear, potentially affecting the precision and efficiency of the gear set.
UNIOIL GEARLUBE is formulated for applications requiring extreme-pressure protection. Its additive system helps protect contacting gear surfaces under demanding pressure conditions, supporting the durability of gears operating under heavy loads and shock. This protection is particularly important for equipment that experiences frequent starts, changes in load or sustained power transmission.
By helping reduce the risk of premature gear damage, GEARLUBE supports more reliable equipment operation and can contribute to lower maintenance costs over time. Actual results depend on operating conditions, equipment design, oil condition and adherence to the manufacturer’s maintenance recommendations.
3. Stable SAE 80W-90 Oil Film
The SAE 80W-90 viscosity grade identifies the oil’s viscosity characteristics at low and high temperatures according to the applicable SAE classification. This multigrade designation makes it suitable for compatible gear systems that require this viscosity grade across varying operating conditions.
During operation, a suitable oil film helps separate gear teeth and other moving components, reducing direct metal-to-metal contact. UNIOIL GEARLUBE is designed to maintain appropriate lubrication in compatible gearboxes, axles and differentials, helping support stable power transmission under demanding service conditions.
Maintaining the correct viscosity is essential because both insufficient and unsuitable oil viscosity can affect lubrication performance. Using SAE 80W-90 where specified by the equipment manufacturer helps ensure that the gear system receives oil with the required viscosity characteristics. Regular inspections and timely oil changes further help maintain effective lubrication throughout the equipment’s service life.
4. Helps Reduce Friction, Noise and Operating Heat
Gear systems depend on consistent lubrication to operate smoothly. When gear teeth repeatedly engage under load, friction develops at their contact surfaces. Excessive friction can contribute to heat generation, noise and wear, potentially affecting the overall performance of the drivetrain.
UNIOIL GEARLUBE helps maintain a lubricating film between contacting surfaces, supporting smoother gear engagement and helping control friction during operation. Appropriate lubrication can also help reduce noise associated with inadequate lubrication or excessive surface wear, although actual noise levels depend on gear design, alignment, load and equipment condition.
By supporting effective lubrication, GEARLUBE helps protect the gear system against friction-related wear and contributes to dependable operation. Maintaining the correct oil level, using the specified viscosity grade and following the recommended service intervals are also important steps in keeping operating temperatures and drivetrain performance within the equipment manufacturer’s intended range.
5. Protection Against Wear, Rust and Corrosion
Gear teeth, shafts and bearings operate under repeated mechanical stress. Over time, inadequate lubrication, contamination or exposure to moisture can contribute to wear and corrosion, affecting component condition and the reliability of the entire drivetrain.
UNIOIL GEARLUBE is designed to provide lubrication and protection for compatible heavy-duty gear applications. Its formulation supports the protection of gear surfaces under demanding operating conditions, while appropriate corrosion protection helps safeguard internal components against rust and related deterioration.
Keeping the oil clean and replacing it according to the manufacturer’s recommendations are essential to maintaining this protection. Regular maintenance also allows users to identify possible leaks, contamination or unusual changes in equipment operation before they develop into more serious problems. Together, suitable gear oil and proper maintenance help preserve component condition and support longer service life.
6. Built for Demanding Vehicles and Equipment
From vehicle axles and differentials to industrial equipment with compatible heavy-duty gear systems, reliable lubrication is essential wherever gears must transmit power under substantial loads. These applications often operate for extended periods and may encounter changing torque, repeated movement and demanding working environments.
UNIOIL GEARLUBE combines the SAE 80W-90 viscosity grade with API GL-5 performance to meet the requirements of compatible gear systems that need extreme-pressure protection. By helping maintain lubrication and protect gear surfaces, it supports dependable operation for vehicles and equipment used in demanding conditions.
For best results, always verify the required oil specification in the equipment manufacturer’s manual. Follow the recommended oil-change interval and maintain the correct oil level to help prevent unnecessary wear and support consistent drivetrain performance.
