Fenner Drives Trantorque GT Keyless Bushings 6202865 40MM 316NM

Fenner Drives Trantorque GT Keyless Bushing 6202865 – 40mm Shaft, 316Nm

The Fenner Drives Trantorque GT Keyless Bushing 6202865 is engineered to provide a high-capacity, zero-backlash connection for mounting components onto 40mm diameter shafts. Utilizing a mechanical interference fit, this bushing ensures secure attachment without the need for traditional keyways, enhancing both performance and reliability.

Key Features

• High Torque Transmission: Capable of transmitting up to 728 Nm of torque, accommodating demanding applications.
• Zero-Backlash Design: Eliminates play between the shaft and mounted component, ensuring precise operation.
• External Counter-Torque Flange: Facilitates easier installation by allowing the system to be held stationary during tightening.
• Exceptional Concentricity: Maintains precise alignment, even under bending loads.
• Minimal Axial Movement: Limited axial displacement during installation preserves component positioning.
• Single Hex Nut Installation: Simplifies the mounting process, reducing downtime and labor.

Specifications

• Bore Diameter: 40 mm
• Outside Diameter: 67 mm
• Overall Length: 79.4 mm
• Transmissible Torque: 728 Nm
• Transmissible Thrust: 34 kN
• Hub Contact Pressure: 29 N/mm²
• Material: Steel with Zinc Chromate/Zinc Phosphate finish
• Temperature Range: -30 to 400°F

Advantages

• Higher Torque Capacity: Outperforms traditional keyed connections in torque transmission.
• Reduced Downtime: Simplified installation and removal processes lead to less equipment downtime.
• Versatile Mounting: Can be installed over existing keyways, offering flexibility in application.
• Adjustability: Provides complete axial and radial adjustability for precise component positioning.

The Trantorque GT Series operates on a simple wedge principle, where an axial force applied via a hex nut engages circular steel rings with mating tapers. This action creates a radial force, contracting one ring to grip the shaft while expanding the other into the component bore, ensuring a secure and reliable connection.

Ideal for applications requiring quick installation and repositioning, the Fenner Drives Trantorque GT Keyless Bushing 6202865 offers a robust solution for mounting gears, cams, timing belt sprockets, conveyor rolls, and more, without the drawbacks of traditional keyed connections.
