Positive locking and resistant to wear – those are the main properties of NSK’s new high-performance seal developed specially for ultra-fine and abrasive foreign matter. By using new materials and a unique design, NSK has succeeded in developing an innovative seal for roller guides with lasting resistance to even ultra-fine foreign matter such as graphite or ceramic dust.  These properties can certainly more than double the linear guides’ life.
