Klüber UNISILKON L 50/2
High-temperature grease for a wide service temperature range
Application Klüber UNISILKON L 50/2
UNISILKON L 50/2 is a long-term lubricating grease for rolling bearings subject to high thermal stress. It has proven effective in applications in the wood, textile and paper industries. UNISILKON L 50/2 can also be used for plain bearings in metal/ plastic material combinations and as assembly aid for rubber parts like seals. UNISILKON L 50/2 is resistant to hot and cold water and water vapour. It is not resistant to most organic solvents, strong acids and alkaline solutions.
Performance, Features & Benefits of Klüber UNISILKON L 50/2 are:
- Made of special raw materials to ensure long-term and for-life lubrication at high temperatures
- Wear reduction for increased component availability due to its good pressure absorption capacity
- Versatile use due to good compatibility with aqueous solutions

Product Description Klüber Unisilkon L 250 L
Manufacturers and operators in the wood, textile or paper industry have to lubricate rolling bearings subject to high temperatures. We designed UNISILKON L 50/2 to meet these requirements. UNISILKON L 50/2 is a high-temperature grease for rolling and plain bearings based on silicone oil and PTFE solid lubricants suitable for a wide service temperature range. The long-term grease UNISILKON L 50/2 has a good wetting ability on metal surfaces and offers good wear protection, resistance to ambient media and thermal stability. You can extend relubrication intervals and reduce cleaning and maintenance costs, so UNISILKON L 50/2 can reduce your operating costs.

Application notes
UNISILKON L 50/2 is neutral towards most metals,
thermoplastics and elastomers. Owing to the many different
elastomer and plastic compositions their compatibility should be
checked prior to series applications. UNISILKON L 50/2 can be
applied by means of spatula, brush, usual metering devices or
the tampon printing method. Please observe the material safety
data sheet.
