KLUBERPHARMA UH1 4

Klüberpharma UH1 4-220/4-460 are specially designed synthetic lubricating oils for the lubrication of steel punches and bronze guides in pharmaceutical tablet presses, especially in the field of highperformance manufacture of tablets.

These lubricating oils offer good wear protection, thus extending the service life of components, as confirmed by oscillation friction wear tests according to DIN E 51834. They also reduce the friction coefficient during start-up of tablet presses and offer improved resistance to bronze. This special property enables a significant reduction in tablet contamination problems occurring in the form of black abrasion particles. Klüberpharma UH1 4-220 has been used very successfully by leading tablet manufacturers for the lubrication of tablet punches.

Klüberpharma UH1 4-220/4-460 are NSF H1 registered and therefore comply with FDA 21 CFR § 178.3570. The lubricants were developed for incidental contact with products and packaging materials in the food-processing, cosmetics, pharmaceutical or animal feed industries. The use of Klüberpharma UH1 4-220/4-460 can contribute to increase reliability of your production processes. We nevertheless recommend conducting an additional risk analysis, e.g. HACCP.

Klüberpharma UH1 4-220/4-460 oils are used for the lubrication of the upper and lower punches and bronze guides in tablet presses. Material / friction combinations:
Upper punches made of hardened steel (e.g. 1.23.63) operating against cast iron (e.g. GGG 40).
Guide rails made of bronze (e.g. 2.0980.03) Lower punches made of hardened steel (e.g. 1.23.63) operating against cast iron (e.g. GGG 40).
Please observe the machine manufacturer's instructions on oil temperature and viscosity selection in the lube chart.
