Applications

For optimal results:

• Clean the lubrication point using OKS 2610/OKS 2611 Universal Cleaner.
• Remove any corrosion protection media before initial filling.
• Ensure all functional surfaces receive sufficient lubrication.
• Slow-moving bearings (DN-value < 50,000) should be filled completely.
• Fast-running bearings (DN-value > 400,000) should be filled to 1/4 of the free inner housing space.
• Follow the instructions provided by the bearing or machine manufacturer.
• Relubricate using a grease gun through grease nipples or an automatic lubrication system.
• Define relubrication intervals and amounts based on service conditions.
• If old grease cannot be removed, limit the amount to avoid over-lubrication.
• Consider a complete exchange of old grease for longer relubrication intervals.
• Mix only with compatible lubricants.
