Overview
The Lovejoy C-226 hub (model 68514426045) is a standard jaw coupling hub engineered for flexible power transmission in industrial machinery. This hub accommodates a 2-1/8″ bore with a 1/2″ x 3/4″ keyway, making it a direct replacement component in Lovejoy C-series coupling assemblies. As a key component in jaw coupling systems, the C-226 hub transmits torque between misaligned shafts while absorbing shock and reducing vibration—critical for maintaining uptime in manufacturing, processing, and automation environments.
Key Features
- Standard C-226 size — 2-1/8″ bore diameter for universal compatibility with common industrial shaft sizes
- 1/2″ x 3/4″ keyway — precision machined keyway ensures positive shaft engagement and load transfer
- Sintered iron or steel construction — durable material composition rated for continuous industrial duty
- Set screw fastening — simple, field-serviceable assembly without special tools
- Drop-in replacement — OEM-compatible geometry for existing C-226 coupling systems
