OKS 481, water resistant high pressure grease for food applications, is now available in 400ml spray packaging. The product is approved according to NSF H1 and can therefore be used in food production equipment. OKS 481 is a fully synthetic calcium sulphonate complex grease designed for high loads and pressures in applications throughout the food production chain.
High shear stability prevents the grease from being squeezed out under extreme mechanical stress such as during heavy vibrations. It provides excellent protection against abrasion and offers a very high protection against alkaline water, acid disinfectants and detergents. The calcium sulphonate soap ensures an excellent water resistance and a very good corrosion protection.
Examples of applications
- Lubrication of rolling and friction bearings, even at high temperatures
- Lubrication of bearings in contact with detergents and disinfectants.
- For mechanical devices such as levers, hinges, exposed to water
Main application areas
- Food and beverage industry, medical industry, agricultural industry, packaging industry
- Approved for applications in food technology. NSF H1 Reg. No. 153878
How to switch from conventional to food grade lubricant.
We recommend that the change is carried out during a regular service stop. All parts to be lubricated must be cleaned and checked to ensure that no residual impurities remain. For cleaning, a cleaning agent approved for food technology is recommended (e.g. OKS 2650 with NSF A1 registration) or one that vaporises without leaving residues. The required limit values for the plant in question must be determined according to the HACCP method at the critical control points.
Change in case of oil lubrication
At the outlet, the oil should be at operating temperature if possible. When the oil is drained, experience has shown that approximately 10% of old oil, wear particles and oxidation products remain in the system. Therefore, the system should be thoroughly cleaned afterwards. Extra care is required for tanks, central lubrication systems, gears and the like. The corresponding drive oil is then topped up and the system is run at normal operating temperatures.
To reduce contamination of the new NSF-registered lubricant, it is recommended that cleaning oil
used.
Replacement in case of grease lubrication
After cleaning, the plant is refilled with the required amount of OKS grease. If disassembly and cleaning of the plant is not possible, the new grease can also be relubricated. In this case, the relubrication interval must be shortened compared to the usual relubrication period, so that the old grease is pressed out. Make sure that the bearings are not overfilled, and that the old grease can be drained off. In addition, ensure that the new lubricant is compatible with the old one.
