• Increased pitch gear diameter allows for larger maximum bore and higher torque capacity than other equivalent size couplings.
• Removable end rings for easy maintenance.
• Coupling halves are joined by special body fitting Metric Class 10,9 (Grade 8) bolts. Adapted nuts are used. While applying tightening torque, nuts rotate and bolts are kept fixed.
• Available in multiple configurations and sizes.
• With end rings, heavy duty
