The GRACO 18B590 is a pulley designed as a 56-tooth HTD (High Torque Drive) drive sheave. It is typically constructed from durable materials suitable for industrial applications, though the specific material is not specified in available sources. This pulley is intended for use within GRACO equipment to transmit power efficiently and reliably, commonly found in systems requiring precise belt-driven motion such as sprayers or grinders.

Key Features:

• HTD Drive Sheave (Pulley)
• 56 Tooth
• Compatible with GRACO equipment requiring a 56-tooth HTD pulley; used with specific belt sizes (e.g., 1200 mm belt in some GRACO grinders)
• High torque transmission capability
• Designed for reliable, long-term operation in industrial environments
• Precision-engineered for smooth belt engagement and reduced wear

Applications:
Used in GRACO equipment such as grinders and sprayers where precise belt-driven power transmission is required. Example: Used with a 1200 mm belt in GRACO GrindLazer models for standard speed operation.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, compatibility, and longevity of the equipment.
• Ensure correct alignment with the mating pulley and belt
• Verify belt tension according to equipment specifications
• Inspect for wear or damage before installation
• Follow all safety procedures outlined in the equipment manual
• Regularly inspect the pulley and belt for signs of wear or misalignment
• Replace worn or damaged components promptly
• Keep the pulley and belt clean and free from debris
