Overview
The Dodge 117175 taper-lock bushing is a Type 2517 sintered steel component engineered for secure, maintenance-free shaft locking in industrial drive systems. This bushing delivers the proven reliability that maintenance technicians and system integrators depend on for conveyor lines, pump drives, fan systems, and general machinery coupling applications. The flangeless, compact design allows for clean integration into confined spaces without protruding hardware.
Key Features
- 8-degree taper geometry — engineered for flush-mounted, wobble-free locking without requiring external flanges
- Sintered steel construction — delivers durability and corrosion resistance in demanding industrial environments
- High holding torque capacity — 11,600 in-lb maximum rated torque for demanding power transmission duties
- Quick installation and removal — standard 1/2″ × 1″ mounting bolts with symmetrical design for simplified assembly
- Sealed design — compact, flangeless profile prevents contamination and eliminates snagging hazards
