Track rollers for X rails

Rollers for TEN, UEN, LA, ML rails

The rollers are single row bearings with 2Z steel shields.
The rollers are made from ultra clean100Cr6 | 52100 core-hardened carbon steel.
Precision ground surfaces ensure a smooth, silent rolling action.
The inner ball retainer is made of steel for high temperature applications to withstand high temperature.
The mounting axle is made in one piece with the inner bearing, for maximum strength.
The integrated roller pivot has concentric or eccentric shape, to allow for preload setting in the different systems
The ball bearing is lubricated for life with a wide temperature ranging lithium soap grease.

The rollers series are also available in stainless steel INOX AISI440 for corrosive ambients.
The stainless steel INOX rollers come with 2RS seals and are lubricated for life with mineral oil for alimentary application or low temperature applications.
