Lower Roller Assembly

Extend crawler system life and minimize unplanned downtime

Extend the overall life of your crawler system. With a larger and thicker thrust washer, the P&H lower roller assembly is designed to provide a longer roller life and helps prevent damage to side frames.

• Improves grease delivery and flow to help extend system life
• Continuous bushing increases bearing areas and has integral grease grooves, which enhances lubrication flow for increased bushing life
• An improved and more robust retention helps decrease rotation and reduces lube system failure
