Heat treatment - Import export

These Roller Followers are lubricated with CLube, a thermosetting solidtype lubricant which fills the inner space of the bearing. CLube is lubricant made of a lot of lubrication oil and fine particles of superhigh molecular polyolefin that are solidified by heat treatment. As the bearing rotates, the lubricating oil oozes out onto the raceway surface in proper quantities, maintaining the lubrication performance for a long period of time.

IKO's Extended Life Specification Machined Type Needle Roller Bearings are treated with a newly developed special heat treatment that enhances the bearing's surface hardness and toughness, and suppresses the generation and growth of damage on the surface. Significant life extension can be achieved under high load or under the condition of lubrication contaminated with foreign substances. In a life comparison test, IKO's special heat treated Extended Life Series products lasted 5 times longer than standard heattreated products.
