Overview
The Dodge 244079 TDT4 tapered bushing assembly is a precision-engineered component designed for industrial motion control and power transmission. This twin-tapered split bushing features a 1-7/16″ bore and is manufactured from durable ductile iron, making it ideal for shaft-mount speed reducers and heavy-duty applications where torque and load capacity are critical.
Key Features
- Twin-Tapered Split Design – Enables keyless shaft connection with precise clamping fit and minimal backlash.
- Ductile Iron Construction – Provides maximum torque and shock load capability; resists wear and seizing.
- Full-Length Shaft Key – Supports both sides of the reducer with flanged bushing mount.
- Fast Installation & Removal – Equipped with removal screws for reliable demount; eliminates fretting and driven shaft damage.
- Wobble Reduction – Fully split bushing design accommodates undersized shafts and reduces radial run-out.
