Grease-Free for Life Ball-and roller-bearings are traditionally lubricated with grease and oils. These lubricants often purge and contaminate the surrounding area, and they may require periodic maintenance through manual or automatic re-lubrication. EDT’s solid polymer lubricant (EPL) drastically reduces - or may even eliminate - the problems associated with traditional lubrication.
Advantages of EPL: • Never require re-lubrication • Consistently deliver the right amount of lubrication • Resist contamination • Stand up to harsh applications and wash downs • Dramatically improve cleanliness
EPL extends bearing life by blocking out contaminants and resisting chemicals that lead to early bearing failure.
Physical characteristics How EDT Polymer Solid of EDT’s Polymer Lubricant works EPL’s micro-porous structure is comprised of millions Solid Lubricant of microscopic pores that hold and release lubricating EPL is a superior solid lubricant that combines oil. As the bearing rotates a micro-porous polymer with high quality, high and the rolling element track performance synthetic lubricant and other warms, oil is released from additives. The chemical composition of the the interconnected micro- polymer, additives and synthetic lubricant vary pores of the solid polymer depending on the lube, and should be selected to lubricate the bearing. Oil is retained in the matrix for the application. For example, food grade through surface tension. The polymer’s micro-porous USDA-H1 approved oils are used in food structure traps oil throughout its entire mass and processing formulas. Additional additives modify slowly delivers lubrication to the bearing as needed. performance characteristics, such as: EPL formulas contain 50% to 80% oil by weight, which • low operating temperature is 2 to 5 times more oil than standard grease. The oil- • reduced friction permeated solid polymer also fills and seals the open • increased load and extreme pressure space of the bearing to block out contaminants that lead to early bearing failure.
