Sinopec L-CKD Heavy Duty Industrial Gear Oil holds the following formal OEM approvals:


Approved (ISO VG 220) by SEW

Sinopec L-CKD Heavy Duty Industrial Gear Oil is suitable for use in:

  • Enclosed industrial gear drives equipped with circulation or splash-lubrication systems, operating under normal, heavy or shock-loaded conditions.

  • Plain or antifriction bearings running under heavy or shock-loaded conditions.

  • Heavy-duty gearboxes in a wide range of applications and industries, for example, in conveyers, presses, extruders

    and crushers in the construction, mining, steel and chemical sectors.

    Features and benefits

  • Excellent extreme pressure(EP) and antiwear performance protect gear teeth and bearing surfaces against seizure,

    scuffing, spalling and wear, even in severe high-load and shock-loading conditions, extending component life and

    lowering operating noise.

  • Excellent thermal and oxidation stability minimise the build up of sludge and varnish deposits that can reduce

    component life; and ensure lubricant stability and longer life even with high bulk oil temperatures, reducing the

    maintenance costs associated with oil changes.

  • Protection against copper corrosion and rusting extends the life of copper alloys and steel components.

  • Good antifoaming properties ensure optimum oil film thickness, protecting against wear, and minimising leakage and

    overflow from gear boxes and oil reservoirs.

  • Excellent water separation properties prevent the formation of emulsions and allow excess water to be easily drained

    from the system, ensuring effective corrosion prevention, optimum lubrication and protecting components against

    surface fatigue and wear.

  • Available in a wide range of viscosity grades to meet the specific needs of the application.

  • Fully compatible with common seal materials, to extend seal life and prevent fluid leaka
