Klüberfood NH1 74-401: High-Performance Lubricating Grease for Food Processing Equipment
Optimized for Safety, Performance, and Compliance
As a food producer or manufacturer of food processing machinery, ensuring machine reliability, regulatory compliance, and maintenance efficiency is essential. Klüberfood NH1 74-401 is specifically designed for the lubrication of production equipment in food and pharmaceutical processing plants, where incidental food contact cannot be excluded.
This high-performance grease combines the load-carrying strength of a synthetic base oil with the versatility of an advanced polyurea thickener, enabling extended relubrication intervals across a wide range of applications.
With its high-temperature resistance, Klüberfood NH1 74-401 can be used in rolling bearings operating at temperatures up to 160°C, withstanding short-term peaks of up to 180°C when relubricated at appropriate intervals.
This lubricant is NSF H1-registered and meets FDA 21 CFR § 178.3570 standards.
Applications
Klüberfood NH1 74-401 is suitable for use in various food-processing sectors, including:
- Bakery, pasta, beverage, meat and fish, tobacco, cereals, grains, and oils industries
Typical applications include:
- Bakery, pasta, beverage, meat and fish, tobacco, cereals, grains, and oils industries
- Drive roller bearings in ovens and proofers
- Conveyors and motor bearings
- Roller bearings in packaging and labeling machines
- Camshafts, linear guides, and sliding components
Application Guidelines
- Can be applied using standard grease application tools, including spatulas, grease guns, and centralized lubrication systems.
- Before application, thoroughly clean all lubrication points to maintain maximum hygiene and food safety standards.
- If cleaning is not feasible, the existing grease should be replaced by purging the system during relubrication.
- For guidance on grease compatibility, relubrication procedures, and optimizing equipment service life, consult Klüber’s Technical Consulting and Sales team.
