The GRACO 121173 is a ball bearing designed for use in GRACO equipment. It is constructed from standard bearing materials (typically steel or chrome steel, though not explicitly stated for this part number), and is intended to provide smooth rotation and reduce friction in mechanical assemblies within GRACO spray equipment and related machinery.

Key Features:

• Ball Bearing
• 3/8"ID x 7/8"OD x 9/32"
• Standard bearing construction (material not explicitly specified for this part number)
• Designed for use in GRACO spray equipment and compatible assemblies
• Compact size for integration into tight spaces
• Designed for reliable, smooth operation in mechanical assemblies
• Ease of maintenance (standard bearing replacement procedures apply)

Applications:
Used in GRACO spray equipment and related machinery where smooth rotation and reduced friction are required in mechanical assemblies.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, longevity, and compatibility with GRACO equipment.
• Ensure the bearing is clean and free from debris before installation
• Lubricate according to manufacturer recommendations if required
• Align the bearing properly with the shaft and housing to prevent premature wear
• Follow equipment-specific installation procedures as outlined in the GRACO manual
