Industrial gearboxes are among the most mechanically stressed components in any manufacturing plant — handling peak loads, shock impacts, thermal cycling, and continuous operation across years without failure. The lubricant inside that gearbox is the only thing standing between the gear surfaces and catastrophic contact. Specify the wrong viscosity grade, use a non-EP oil where extreme pressure protection is required, or run a gearbox beyond its oil change interval, and the consequences are gear pitting, bearing seizure, and costly unplanned downtime.
Imperiea Engineering & Sourcing Pvt. Ltd. is a trusted EP gear oil supplier in Pune — supplying Kixx Gear EP, Savsol Autogear, and Savsol Synth Autogear series to gearbox maintenance teams across Pune’s industrial zones including Chakan MIDC, Ranjangaon MIDC, PCMC, Talegaon, and Bhosari.
What is EP Gear Oil ISO 220 — and Why Does the Grade Matter?
ISO 220 refers to a kinematic viscosity of 220 centistokes at 40°C — a heavy-duty viscosity grade in the industrial gear oil classification. ‘EP’ stands for Extreme Pressure — indicating the presence of sulphur-phosphorus additive chemistry that forms a protective film on gear tooth surfaces under high loads, preventing metal-to-metal contact and micropitting.
ISO 220 EP gear oil is the most commonly specified grade for enclosed industrial gearboxes operating at moderate speeds with medium-to-heavy loads. It meets AGMA 250.04 Grade 5 and DIN 51517 Part 3 CLP specifications — the two standards most widely referenced by gearbox OEMs.
ISO EP Gear Oil Viscosity Grade Selection Guide
| ISO Grade | AGMA Grade | Typical Application | Common Gearbox Types |
| ISO 68 | AGMA 2 | High-speed, lightly loaded | Turbine reduction gears, high-speed spindles |
| ISO 100 | AGMA 3 | Medium speed, moderate load | Conveyor drives, small enclosed gearboxes |
| ISO 150 | AGMA 4 | Medium-heavy, moderate speed | General industrial drives, fan gearboxes |
| ISO 220 | AGMA 5 | Medium speed, heavy load — MOST COMMON | Rolling mill drives, conveyor reducers, general industry |
| ISO 320 | AGMA 6 | Low-medium speed, heavy load | Crushers, extruders, heavy conveyors |
| ISO 460 | AGMA 7 | Low speed, very heavy load | Cement mills, steel plant drives, mining equipment |

We supply genuine products with full technical documentation for OEM warranty and ISO compliance purposes.
AGMA vs DIN 51517 — Understanding the Two Gear Oil Standards
Most Pune industrial plants encounter two gear oil standards — AGMA (American Gear Manufacturers Association) and DIN 51517 (German standard). Here is a quick reference:
- AGMA 250.04 — US-origin standard. Specifies gear oils by AGMA numbers (2 through 8 for EP grades). Widely used by US and Indian gearbox OEMs.
- DIN 51517 Part 3 (CLP) — German standard. Specifies enclosed gear oils by ISO viscosity grade + CLP designation. Used by most European gearbox OEMs (SEW-Eurodrive, Flender, Bonfiglioli).
- Imperiea supplies gear oils meeting both standards. When ordering, share your gearbox OEM brand and model — we will confirm the correct Kixx or Savsol grade that meets your OEM specification.
Frequently Asked Questions — EP Gear Oil Pune
Q: How do I know if my gearbox needs EP (Extreme Pressure) gear oil or a regular industrial oil?
A: If your gearbox contains helical, bevel, or worm gears running under moderate-to-high load, it almost certainly requires an EP gear oil. Only very lightly loaded, high-speed gear sets (like turbine reduction gears) use non-EP oils. When in doubt, check the gearbox OEM nameplate or manual — it will specify the oil type and viscosity grade.
Q: How often should gear oil be changed in industrial gearboxes?
A: For mineral EP gear oils (ISO 220), the standard change interval is 3,000–5,000 operating hours or 12 months for normal conditions. For synthetic gear oils, intervals of 8,000–15,000 hours are achievable. High-temperature gearboxes, water-contaminated environments, and systems with frequent shock loading require shorter intervals. Annual oil analysis is the best way to determine the actual condition and optimal change interval.
Q: Do you supply EP gear oil in both 20-litre and 210-litre drums in Pune?
A: Yes. We supply all Kixx Gear EP and Savsol Autogear grades in 20-litre packs, 55-litre drums, and 210-litre drums. For high-volume plants in Chakan or Ranjangaon MIDC, we can discuss bulk supply arrangements with scheduled delivery.
Q: What is the difference between ISO 220 and ISO 320 gear oil?
A: ISO 320 is approximately 45% more viscous than ISO 220 at 40°C. ISO 320 is used in slower-speed, heavier-load gearboxes — typically in crushers, extruders, and heavy conveyor drives. ISO 220 is the standard grade for general industrial gearboxes. Using ISO 320 where 220 is specified can reduce efficiency and cause temperature rise — always follow the OEM recommendation.
