Long-life Pinion Shaft with cage and roller assembly
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 contaminate the lubricant. NSK's Long-life Pinion Shaft with Cage and Roller Assembly (especially for Hydraulic Excavators) provides a superior service life (increase more than twice), offers greater reliability and improved surface fatigue strength.
