Product description
- Synthetic EP gear and circulating oil
- Polyglycol base for highly loaded industrial gears
- Very high viscosity index
- Optimal for spur, bevel, planetary and worm gears
Bathan KO 220 PG is a synthetic high-performance gear and circulating oil based on polyglycol, developed for heavily stressed gear types. Thanks to the high viscosity index, the lubrication performance remains stable and reliable even with temperature and load fluctuations. Ideal for industrial applications with high demands on efficiency and protection.
Mode of action
The oil forms an extremely resilient lubricating film that significantly reduces friction and wear. The polyglycol base ensures that the oil retains its lubricity even under high pressure loads or vibrations. This protects metal surfaces in the long term, stabilizes temperatures and extends the service life of the gears.
Properties & advantages
- Maximum wear protection / Reliably protects under high pressures, peak loads and vibrations – ideal for demanding industrial gears.
- Stable lubrication performance / High viscosity index guarantees constant performance under temperature and load fluctuations.
- Higher system availability / Reduced wear reduces downtimes and extends the service life of the gears.
- Efficient operation / Optimized lubrication ensures smooth running and lower energy losses.
- Less maintenance / Longer oil life and more stable film thickness reduce maintenance intervals and operating costs.

Frequently asked questions about Bathan KO 220 PG
The most important questions and answers!
Bathan KO 220 PG was specially developed for highly stressed industrial gears:
- Spur gears – for parallel shaft arrangement
- Bevel gears – for intersecting shafts
- Planetary gears – for compact design with high transmission ratio
- Worm gears – for high reductions
The oil is particularly suitable for applications with high pressure loads, shocks or vibrations.
The viscosity index describes how much the viscosity (fluidity) of an oil changes with temperature changes:
- Normal mineral oil: VI approx. 95-110
- Bathan KO 220 PG: VI 195
Your advantage: The lubricating properties remain almost constant over an extremely wide temperature range (-33°C to +250°C). That means:
- Reliable lubrication during cold start
- Stable lubricating film even at high operating temperatures
- No performance losses with temperature fluctuations
Polyglycol-based oils such as Bathan KO 220 PG offer significant advantages:
✅ Higher lubrication safety – better lubricating film under extreme conditions ✅ Better temperature stability – higher viscosity index ✅ Lower friction – lower coefficient of friction = energy saving ✅ Longer service life – better oxidation and aging resistance ✅ Lower operating temperatures – better heat dissipation ✅ Extended oil change intervals – cost saving
Important: Compatibility with existing materials should be checked during conversion.
In principle, mixing is not recommended, as polyglycol oils are not miscible with mineral oil-based or PAO oils.
When changing oil from mineral oil to Bathan KO 220 PG:
- Completely empty the gearbox
- Thoroughly flush the system (ideally with polyglycol flushing oil)
- Fill in fresh Bathan KO 220 PG
Advantage of the conversion: The superior properties of the polyglycol oil only come into their own with a complete replacement.
Our service team will be happy to advise you on the conversion!
