Value Collection 28H1006FSPB3/4 Timing Belt Pulley 28T

Product Description

The VALUE COLLECTION 28H1006FSPB3/4 is a 28-tooth timing belt pulley designed for synchronous drive applications in industrial and mechanical power transmission systems. It features a 3/4-inch inside bore diameter and a 4.402-inch outside diameter, with a pitch diameter of 4.456 inches. The pulley accepts H-series timing belts with a 1-inch belt width. Constructed from steel cast iron, this pulley delivers the rigidity and wear resistance required for continuous-duty drive train applications. Installation is typically performed by mechanical technicians or millwrights working on conveyor systems, machine drives, or other synchronized belt-drive assemblies.

This timing belt pulley is suited for use in industrial machinery, conveyor lines, and synchronous drive systems that use H-profile timing belts. The H belt trade size designation indicates compatibility with standard H-pitch belt configurations commonly found in mid-range power transmission setups. It is appropriate for both OEM replacement and new-build drive system configurations where precise tooth engagement and consistent belt tracking are required.

Key Features

• 28-tooth profile for accurate synchronous belt engagement
• 3/4-inch bore diameter for direct shaft mounting
• 4.456-inch pitch diameter for precise drive ratio calculations
• 4.402-inch outside diameter for standard H-series belt fitment
• Steel cast iron construction for high rigidity and wear resistance
• Compatible with 1-inch wide H-profile timing belts

Compatibility

Designed for use with H-series timing belts with a 1-inch belt width. Suitable as an OEM-style or aftermarket replacement pulley in industrial synchronous drive systems using H-pitch belt configurations.

Installation Notes

Installation should be performed by a qualified millwright or mechanical technician. Shut down and lock out all power to the drive system before replacing or installing the pulley. Ensure the shaft diameter matches the 3/4-inch bore before mounting, and verify belt tension and alignment according to the drive system manufacturer specifications. Proper alignment of the pulley to mating components is critical to prevent premature belt and bearing wear.
