The GRACO 187726 is a bearing link component, primarily made from acetal, designed for use within GRACO air-operated diaphragm pumps. Its main function is to facilitate smooth mechanical linkage and movement within the pump assembly, ensuring reliable operation and reduced wear on moving parts.

Key Features:

• Bearing, Link
• Acetal
• GRACO air-operated diaphragm pumps (e.g., Husky 715 series)
• Durable acetal construction for wear resistance
• Designed for smooth linkage and reduced friction
• Essential for reliable pump operation

Applications:
Used in GRACO air-operated diaphragm pumps for various industrial, mining, and agricultural applications where reliable fluid transfer is required.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, longevity, and safety of the equipment.
• Ensure all mating surfaces are clean and free of debris before installation.
• Apply appropriate grease to the inside surfaces of the shift saddle and link assembly as specified in the manual.
• Hold the link assembly firmly in place and install the screw, torquing to 7–9 in-lb (0.8–1.0 N·m).
• Reinstall the air valve and o-ring as per the equipment manual instructions.
• Regularly inspect the bearing link for wear or damage.
• Lubricate as recommended in the manual.
• Replace the bearing link if excessive wear or play is detected.
