Stilex PM extends the service life and enhances the performance of sensitive and critical components, such as bearings, by providing durable, high-temperature greases designed to withstand harsh operating conditions. Since bearings are particularly exposed to demanding environmental factors such as dust, high temperatures, moisture, vibration, corrosion, and heavy loads, proper lubrication is crucial.
NSF Registration No.: 171026
Reduced lubrication costs thanks to low consumption
Reduced wastewater discharge thanks to excellent water resistance Stilex PM is a long-lasting, high-temperature grease formulated with high-tech, refined paraffinic mineral base oil and polyurea thickener. It has a wide operating temperature range. It is suitable for use in ball bearings up to 185°C and can be used in centralized lubrication systems. These greases are highly adhesive and water-resistant under both static and dynamic loads.
Traditional soap-based greases separate from the oil in vibrating systems, causing leakage and leading to bearing failures. Stilex PM’s natural vibration-dampening structure and effective wear protection properties deliver superior performance and prevent unplanned downtime.
Wear protection
Reduction in bearing costs
Good pumpability in centralized lubrication systems
Leaves no carbon residue
It is a long-lasting high-temperature grease 
Bearings used in the iron and steel industry that are subjected to vibrating and impact loads, operate at medium to high speeds, and are exposed to high temperatures
In the automotive aftermarket sector, where metal and elastomer applications are used under demanding conditions
In conveyor bed systems with moving belts operating under harsh conditions
In vibrating mechanisms where steel and plastic components work together,
It is suitable for bearing and housing applications operating under high temperatures, vibrating loads, and harsh operating conditions.
