Industrial Gear Oil
Formulation.
Enclosed industrial gear drives are not automotive axles. We formulate ISO-graded CLP gear oils — helical, bevel, worm and planetary — built for FZG load capacity, micropitting protection and long service life, with the formula and IP transferred to you.
Continuous load,
not shock load.
An automotive GL-5 axle oil is tuned for shock-loaded hypoid gears. An enclosed industrial gear drive is a different machine entirely.
It runs continuously under high, steady load, often with water ingress and circulating systems — so the formulation priorities become micropitting protection, FZG scuffing capacity, demulsibility, foam control, filterability and long oxidation life, all graded by ISO viscosity. That is why industrial gear oils are specified as CLP / CKC / CKD to DIN 51517-3 and ISO 12925-1, not as GL-5. For worm drives, the system also has to be yellow-metal safe for bronze wheels.
The targets a CLP oil
is judged on.
Public performance targets and standard reference ranges — not a recipe.
A balanced
sulfur-phosphorus system.
Industrial gear EP performance comes from a sulfur-phosphorus system: sulfur carriers deliver extreme-pressure film strength while phosphorus compounds handle anti-wear. The published art is explicit that the sulfur-to-phosphorus mass ratio matters — an optimum band of roughly 8–11 — outside which EP and friction performance fall off and the blend can destabilise (see additive-system patents such as EP2412790A1 and US7902132B2). To that core go anti-foam, demulsifiers, antioxidants, rust inhibitors and — for bronze worm wheels — a metal deactivator.
Composition follows standard structure: base oil ~80–95% + EP/AW additive ~2–8% (public reference). What the patents do not give is the exact EP/AW balance, treat rates and base-oil blend that hit your FZG stage and micropitting target at a competitive cost — and that is the work.
Validated on the
methods that matter.
Each candidate is benchmarked against your reference and validated on FZG scuffing, FVA micropitting, FE8 bearing wear, D2711 demulsibility, D892 foam, D665 rust and full viscometrics.
Your formula —
not a patent's.
We convert the public art into a manufacturable, cost-optimised, globally sourced industrial gear oil that meets your CLP target — and hand it over as your asset.
Industrial gear oil —
questions.
Automotive GL-5 oils are built for shock-loaded hypoid axles and use an aggressive sulfur-phosphorus EP system. Enclosed industrial gear drives — helical, bevel, worm and planetary — run continuously under high steady load, so the priorities shift to micropitting protection, FZG load capacity, demulsibility, foam control, filterability and long oxidation life, graded by ISO viscosity (CLP / CKD). They are different products built to different standards (DIN 51517-3, ISO 12925-1, AGMA).
FZG (DIN 51354 / ISO 14635) measures the load stage at which scuffing occurs on a gear rig — a core measure of an industrial gear oil's extreme-pressure capacity. Industrial CLP oils typically target a high fail-load stage; we benchmark and formulate to your required stage.
Yes. Worm drives use bronze wheels, so the EP/AW system and any sulfur carriers must be yellow-metal compatible, usually with a metal deactivator. We formulate worm-gear and compounded oils that protect steel without attacking bronze.
Yes — under NDA, with full IP transfer. This page shows the public chemistry, standards and patent landscape; the exact EP/AW balance, treat rates and BOM are developed to your gearbox duty and base oil and handed over as your asset.
