Product Description
GF65-N Driveflex Steel Pilot Bore Hub - Standard Hub
The GF65-N Driveflex Steel Pilot Bore Hub is a precision-engineered component designed for flexible shaft coupling applications requiring larger bore capacities. This standard hub length steel hub features a pilot bore configuration with a 25mm pilot hole and maximum bore size of 65mm, making it ideal for high-capacity torque transmission with built-in misalignment compensation.
Key Features:
- Driveflex flexible shaft coupling technology
- Steel construction with pilot bore design (25mm pilot hole, Max bore size: 65mm)
- Standard hub length of 70mm for reliable engagement and load distribution
- Flexible shaft connection for positive torque transmission
- Compensates for axial, radial, and angular shaft misalignment
- Maintenance-free operation due to nylon/steel material combination
- Curved-tooth design that minimizes wear and eliminates edge pressure on splines
- High-quality steel construction for durability and strength
Ideal Applications:
- Industrial machinery and heavy equipment
- Hydraulic systems and high-capacity pumps
- Large-scale power transmission systems
- Heavy-duty mechanical drives
- Applications requiring misalignment compensation with larger shaft diameters
- Equipment benefiting from extended hub support in demanding environments
Important Note: For a complete coupling assembly, you will need to purchase two GF65-N hubs and one matching Driveflex nylon sleeve. This hub is supplied individually.
