Value Collection 20XL025-6FA-1/4 Timing Belt Pulley

Product Description

The VALUE COLLECTION 20XL025-6FA-1/4 is a 20-tooth hub flange timing belt pulley designed for use with XL-series timing belts. Machined from aluminum, it features a 1/4 inch bore, a 1.253 inch outside diameter, and a 1.273 inch pitch diameter. The flanged design keeps the belt tracked on the pulley during operation, reducing the risk of belt walk in precision drive applications. This pulley is a standard component in light-duty power transmission assemblies where accurate indexing and repeatable positioning are required. Maintenance technicians and mechanical assemblers typically install this type of pulley in automated equipment, conveyor systems, and motion control setups.

This pulley is suited for light industrial and automation applications that use XL-profile timing belts with a 1/4 inch belt width. Typical installation scenarios include small conveyor drives, stepper motor power transmission stages, and positioning actuators found in manufacturing and laboratory equipment. The compact dimensions and aluminum construction make it a practical choice for weight-sensitive or corrosion-conscious assemblies where steel would be excessive.

Key Features

• 20-tooth XL-series tooth profile for positive, no-slip power transmission
• Aluminum construction reduces rotating mass and resists corrosion
• Hub flange design helps retain belt alignment during operation
• 1/4 inch bore accommodates standard small-shaft drive configurations
• 0.438 inch face width sized to match 1/4 inch XL timing belt width

Compatibility

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

Installation Notes

Installation is typically performed by mechanical technicians or machine builders. De-energize and lock out all power to the drive system before removing or installing any pulley. Secure the pulley to the shaft using the appropriate set screw or retaining hardware, and confirm belt tension and alignment before returning the assembly to service. Follow the equipment manufacturer guidelines and applicable ANSI/ASME machinery safety standards during installation.
