Klüberoil 4 UH1-100 N Synthetic Food Grade Gear Oil
Klüberoil 4 UH1-100 N for Food and Pharmaceutical Equipment
Klüberoil 4 UH1-100 N is a synthetic food-grade lubricating oil based on polyalphaolefin (PAO). It is formulated for machinery where reliable lubrication is required together with strict hygiene considerations. The product is registered as NSF H1 and certified according to ISO 21469, making it suitable for applications where incidental food contact may be possible.
Key Performance Features
| Feature | Description |
|---|---|
| Synthetic PAO Base Oil | Provides good oxidation and ageing resistance for extended lubrication intervals |
| ISO VG 100 | Suitable for applications requiring a medium-viscosity gear oil |
| NSF H1 Registered | Intended for use where incidental contact with food may occur |
| High Load Protection | Helps protect gears against scuffing under demanding loads |
| Wear Protection | Supports longer service life of gears and rolling bearings |
| Low Foaming Tendency | Helps maintain stable lubrication during operation |
| Good Elastomer Compatibility | Designed for compatibility with many commonly used sealing materials |
| Wide Temperature Capability | Service temperature upper limit is approximately 120°C |
The ISO VG 100 grade has a kinematic viscosity of approximately 100 mm²/s at 40°C and 14 mm²/s at 100°C, with a viscosity index of at least 140.
Typical Applications
Klüberoil 4 UH1-100 N can be considered for a range of lubrication points in food and pharmaceutical production equipment, including:
- Industrial gearboxes
- Spur and bevel gears
- Worm gears
- Rolling bearings
- Spindles and joints
- Drive and transport chains
- Food and beverage conveying equipment
- Pharmaceutical processing machinery
It is also listed for applications such as tablet presses and other pharmaceutical equipment where an ISO VG 100 food-grade oil is required.

Why Choose an ISO VG 100 Food Grade Gear Oil?
Choosing the correct viscosity is important for gearbox performance. Klüberoil 4 UH1-100 N provides a balance between lubricant film formation and flow characteristics for equipment designed around an ISO VG 100 oil.
For food-processing environments, the NSF H1 classification is particularly relevant because lubricants used in these areas need to be selected with potential incidental food contact in mind. NSF lists Klüberoil 4 UH1-100 N under H1 and ISO 21469, registration number 121173.
Important: NSF H1 registration does not mean the lubricant is intended for direct or intentional food contact. Equipment operators should still follow their lubrication program, contamination-control procedures and applicable HACCP requirements.
