Planetary gears in swing / travel reduction gears for construction and mining machinery are used in severe lubrication conditions where abrasion powder from gears and other foreign material can become mixed with the lubricant. NSK's Long-life pinion shaft with cage and roller assembly (especially for Hydraulic Excavators) provides a superior service life (achieving more than a twofold increase), offers greater reliability and improved surface fatigue strength.
* Inform NSK of preferred size for simultaneous delivery of shaft with assembly.
