Heavy Load Enclosed Gear Antifoam Hydraulic Oil PetroChina Kunlun L-CKD 320

PetroChina Kunlun L-CKD 320 Heavy Load Enclosed Gear Oil Anti-Foam Protection

Kunlun L-CKD 320 industrial enclosed gear oil is a heavy duty gear lubricant produced by PetroChina Lubricant Company for enclosed gear drives that operate under the most demanding conditions. Produced to GB 5903-2011 and meeting AIST 224, this ISO VG 320 heavy duty industrial gear oil delivers outstanding extreme pressure and anti-wear performance in gear units where flank contact stress exceeds 1100 MPa.

Product Overview

This 320-grade enclosed gear oil is intended for enclosed gear drives in metallurgy and steel rolling, cement plants and underground mining, where heavy loads, high temperatures and shock loads are common. Its typical kinematic viscosity at 40 °C is about 325.6 mm²/s with a viscosity index of 92.

A robust additive system allows the heavy duty industrial gear oil to resist scuffing, wear and scoring on gear flanks, while safeguarding internal parts against rust and corrosion even in water-containing duty. The fluid also provides a stable oil film for effective lubrication and heat dissipation, and its oxidation and thermal stability support a long oil service life and fewer unplanned repairs.

Key Performance Advantages

• Excellent extreme pressure and anti-wear performance: prevents gear flank scuffing, wear and scoring so the drive keeps running smoothly.
• Excellent rust and corrosion resistance: guards machine parts against corrosion even in water-containing duty.
• Excellent foam resistance: provides a stable oil film for effective lubrication and heat dissipation.
• Excellent oxidation and thermal stability: supports a long oil service life even at high temperature.
• Built for severe duty: suits gear systems carrying heavy loads, high temperatures and shock loads.
• Lower maintenance: long oil life and reliable protection reduce downtime in continuous plants.

Proven Applications

• Steel works including Shougang, Ma'anshan Steel, Shagang, Baotou Steel, Nanjing Steel, Panzhihua Steel, Anshan Steel and Tianjin Steel Pipe: raw mills, pelletising, rolling mill rolls, converter tilting, film pumps and crane gearboxes.
• Coal mining including Datong Coal, Xishan Coal, Jinmei Group and Guizhou Panjiang: shearer ranging arms, traction boxes, roadheader travel reducers and cutting reducers.
• Cement plants including Conch Cement and Jidong Cement: coal mills, raw vertical mills, rotary kilns and bucket elevator reducers.
• Other heavy industry including China Aluminum, Taiyuan Heavy and Nine Dragons Paper gear reducers.
