L-CKJ Open Gear Oil is a heavy-duty lubricant engineered for open gear systems working under extreme loads and harsh industrial conditions.
It's made to stick fast to gear surfaces, form a durable protective film, and stand up to dust, water, and temperature changes, keeping your heavy machinery running smoothly with less wear and fewer breakdowns.
It's a go-to choice for industrial sites that need reliable gear protection and long equipment life.

Material Description
This oil is blended from high-purity mineral base oil, plus a high-performance additive package including sulfur-phosphorus extreme pressure agents, antioxidants, rust inhibitors and anti-wear additives. It contains no asphalt, chlorine or heavy metals, complying with industrial environmental standards while ensuring stable lubrication performance.
