Standard Grease Types
KML Cast Iron Mounted Bearing Units are lubricated with Chevron SRI#2 from the factory. Chevron SRI#2 is a high temperature ball and roller bearing grease. It is formulated using a synthetic polyurea ashless organic thickener and rust and oxidation inhibitors. This grease provides superior rust protection in severe applications in the presence of both salt and fresh water. The temperature range of the Chevron SRI#2 is -20°F to 350°F (-29°C to 177°C). It provides excellent bearing life at operating temperatures of 185°F to 230°F (85°C to 110°C). KML nitrile rubber seals will begin to deteriorate above 230°F temperature. KML bearing units normal grease content is about one third to one half of the internal space inside the bearing. The grease used for replenishment should checked for compatibility before application.
KML Cast Iron Mounted Bearing Units can be supplied with alternate solid-lube lubrication options. (Additional lead time required).
KML Solid Polymer 350 – KML offers 350°F (177°C) temperature rating with increased lubrication performance. This lubricant makes relubrication unnecessary while increasing the performance of the bearing with Extreme Pressure additives. In addition, lubricity is enhanced with a Friction Reduction additive making this a truly High Performance Lubrication Option.
