The GRACO 181659 is a bearing sleeve, typically made from acetal, designed to provide smooth operation and support within GRACO displacement pumps. Its primary function is to reduce friction and wear between moving parts, ensuring reliable performance in demanding industrial applications.

Key Features:

• Bearing, Sleeve
• Acetal (as referenced in GRACO C Series manuals)
• Compatible with GRACO C Series displacement pumps (e.g., Models 222012, 222017, 222019, 239388)
• Durable acetal construction for reduced friction and wear
• Compact design for easy integration into pump assemblies
• Reliable performance in high-duty cycle applications

Applications:
Used in GRACO displacement pumps for industrial fluid handling, including lubrication, chemical transfer, and spray foam systems.

Installation Notes:

• Using genuine GRACO parts ensures optimal fit, performance, and longevity of the equipment.
• Lubricate the displacement rod before installation for smooth operation
• If the old sleeve is difficult to remove, consult a GRACO representative for guidance
• Follow torque specifications for related components (e.g., con-rod torqued to 200 in-lb or 23 N.m)
• Regularly inspect the bearing sleeve for wear and replace as needed
• Use only recommended lubricants and replacement parts
• Refer to the equipment manual for detailed maintenance procedures
