The GRACO 166056 Bearing, Piston is a replacement part designed for use in GRACO pumps and fluid handling equipment. Its material is not specified in available sources, but typical piston bearings are made from durable metals or engineered plastics for wear resistance. This part is intended to support the piston within the pump assembly, ensuring smooth operation and reducing friction between moving components.

Key Features:

• Piston Bearing
• Supports piston movement
• Reduces friction and wear
• Designed for reliability and long service life

Applications:
Used in GRACO pumps and fluid transfer systems for lubrication, maintenance, and industrial fluid handling applications.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, compatibility, and longevity of the equipment.
• Ensure the pump is depressurized and isolated before installation.
• Clean the piston and bearing surfaces thoroughly before fitting the new bearing.
• Follow the manufacturer’s recommended torque and alignment procedures.
• Inspect for wear or damage on related components during replacement.
• Regularly inspect the bearing for signs of wear or damage.
• Replace the bearing as part of scheduled maintenance or when performance issues arise.
• Use only genuine GRACO replacement parts for best results.
