Value Collection 16XL025-6FA-1/4 Timing Belt Pulley

Product Description

The VALUE COLLECTION 16XL025-6FA-1/4 is a 16-tooth, hub flange timing belt pulley designed for synchronous power transmission in light industrial, automation, and mechanical drive applications. Machined from aluminum, it offers a low rotational mass while maintaining dimensional accuracy for precise belt tracking. Key specifications include a 1.019-inch pitch diameter, a 0.25-inch (1/4 inch) belt width, and a 0.438-inch face width. The bore measures 0.25 inches inside diameter with a 1-inch outside diameter. This pulley is installed by mechanical technicians and machine builders working on timing-critical drive systems.

This pulley is suited for use in small-footprint drive assemblies where an XL-series timing belt is specified. Typical applications include conveyor systems, CNC equipment, robotics, and other precision motion control setups requiring accurate tooth engagement and repeatable positioning. The integrated hub flange aids in axial belt retention, reducing lateral belt migration during operation. It is appropriate for both OEM builds and maintenance replacement scenarios.

Key Features

• 16-tooth XL-series profile for positive synchronous drive engagement
• Aluminum construction reduces rotational inertia and resists corrosion
• Integrated hub flange retains belt laterally without additional hardware
• 1.019-inch pitch diameter for accurate speed and torque calculations
• 0.438-inch face width accommodates 1/4-inch XL timing belts
• Compact 1-inch outside diameter suits space-constrained drive layouts

Compatibility

Designed for use with XL-series timing belts with a 1/4-inch belt width. Verify bore diameter, pitch diameter, and tooth profile match the driven shaft and belt specifications before installation.

Installation Notes

Installation should be performed by a qualified mechanical technician familiar with synchronous drive systems. Disconnect and lock out all power sources before servicing the drive assembly. Secure the pulley to the shaft using the appropriate set screw or keyway fasteners and confirm proper belt tension per the belt manufacturer's guidelines. Misalignment between driver and driven pulleys can cause premature belt and pulley wear.
