Mechanical oil is refined from high‑grade base oils and formulated with antioxidants, anti‑wear agents, and anti‑aging additives; it complies with the GB 443‑89 standard.
This product is formulated with refined mineral oil as the base stock, blended with high‑temperature antioxidants, composite coking inhibitors, and other additives. It is a pale yellow, transparent liquid exhibiting excellent lubricity, superior thermal stability, and low viscosity for easy pumping. It resists coking, has low ash content, and is non‑toxic, non‑corrosive, and environmentally friendly.
CKD Industrial Closed-Gear Oil (Heavy-Duty)
The wax-free nature of olefin base oils imparts excellent low‑temperature fluidity to the product. In addition, they exhibit outstanding extreme‑pressure properties and can withstand impact loads. The inherently low shear‑thinning characteristics of these base oils help reduce fluid friction in areas with irregular surfaces, such as gear teeth and rolling‑element bearing load zones. Lower fluid friction leads to reduced operating temperatures, thereby enhancing gear efficiency.
CKC Industrial Closed-Gear Oil (Medium Load)
The wax-free nature of α‑olefin base oils imparts excellent low‑temperature fluidity to the product. Moreover, they exhibit outstanding extreme‑pressure properties and can withstand impact loads. The inherently low shear‑thinning characteristics of these base oils help reduce fluid friction in areas with irregular surfaces, such as gear teeth and rolling‑element bearing load zones. By lowering fluid friction, operating temperatures are reduced, thereby enhancing gear efficiency.
Wells transformer oil is composed of refined mineral base oil and selected antioxidants, contains no PCBs (polychlorinated biphenyls), and is suitable for insulation and cooling in transformers, oil-immersed switches, and other electrical insulation equipment. This product is classified into grades such as 10, 25, and 45 according to its low-temperature performance.
Spindle bearing oil is a premium-grade spindle lubricant formulated by blending refined base oils with a variety of antioxidant, anti-corrosion, and rust‑inhibiting additives. The inclusion of carefully selected anti-wear agents further enhances its exceptional lubricating performance, effectively reducing spindle temperature rise, minimizing wear, and extending service life. This product is available in grades 2, 5, 7, 10, and 15, classified according to kinematic viscosity at 40°C.
Extreme-pressure turbine worm gear oil
Standard worm gear oil is suitable for lubricating worm gear pairs operating under non‑impact loads and in humid environments, such as copper–steel transmission systems found in ships and submarines. Extreme‑pressure worm gear oil, on the other hand, is designed to handle impact loads and high pressures typical of steel‑working applications, making it ideal for lubricating worm gear sets—such as steel leadscrews with bronze nuts—as well as spur gears; it can also be used as a substitute for rolling‑mill oils.
This product is formulated with refined mineral oil as the base stock, blended with high-performance additives that provide oxidation resistance and rust inhibition. Available in two grades—DFI and DFII—based on different vacuum levels, it meets the sealing and lubrication requirements of vacuum pumps operating at various degrees of vacuum.
This product is formulated with refined base oils and premium imported additives that provide wear resistance, anti-foaming properties, and excellent emulsion stability. It is manufactured according to a scientifically optimized formulation. Compliance standard: GB 11120‑89, meeting the quality levels of comparable foreign‑made lubricants.
Low‑pour‑point, anti‑wear hydraulic oil
Wells’ low‑pour‑point series of anti‑wear hydraulic oils are high‑performance, wear‑resistant hydraulic fluids designed to meet the demands of a wide range of hydraulic equipment. This product line extends the service life of both the oil and the filters while providing optimal protection for the equipment, thereby reducing maintenance costs and product disposal expenses. Developed in collaboration with leading equipment manufacturers, this series satisfies the stringent requirements of precision hydraulic systems, including high‑pressure, high‑output pumps, as well as other critical components such as low‑clearance servo valves and high‑precision CNC machine tools.
Wells marine diesel engine oil is formulated with polyalphaolefin (PAO) fully synthetic base oil and imported composite additives, blended using advanced manufacturing technology.
