Overview
The Fenner Drives 6202865 Trantorque GT Series 40MM keyless bushing provides a zero-backlash frictional connection that will never wear or pound out and can accommodate high-torque, thrust, bending, and/or radial loads. This keyless locking device eliminates the need for traditional keyed connections, offering superior torque transmission capacity and exceptional concentricity.
Key Features
- Zero-backlash frictional connection that will never wear or pound out
- Exceptional concentricity while maintaining the ability to accommodate bending loads
- Single hex nut for speed and simplicity of installation
- Ability to transmit higher torques than keyed connections and true zero-backlash
- Complete axial and radial adjustability with simple installation, adjustment and removal
- Limited axial movement during installation
Technical Specifications
The 6202865 is designed with a 40MM shaft diameter and 67MM outer bore diameter, rated for 728 Nm torque transmission and 34 kN thrust load capacity. Installation torque is 317 Nm. Steel construction with zinc chromate/zinc phosphate finish. Weight: 2.65 lbs. Operating temperature range: -30°F to 400°F.
Typical Applications
The Trantorque GT series is ideal for shaft-to-hub connections in:
- Coupling assemblies requiring zero-backlash operation
- High-torque drive systems and power transmission equipment
- Precision machinery where concentricity is critical
- Applications where repositioning flexibility is needed without keyway constraints
- Industrial drives and motion control systems
