Overview
The Toronto Gear QD28H100 is an Imperial-pitch timing pulley engineered for synchronous belt drive systems requiring a 28-tooth configuration with SDS quick-disconnect bushing mounting. Toronto Gear Works manufactures this component to ISO standards for OEM and MRO applications across packaging machinery, automation, CNC, robotics, and industrial drive systems. The H-profile designation indicates HTD (Synchronous) tooth geometry designed to work with 1-inch-wide timing belts. The SDS bushing interface provides tool-free installation and removal, reducing downtime during maintenance or replacement cycles.
