• Increased pitch gear diameter allows for larger maximum bore and higher torque capacity than other equivalent size couplings.
• MT coupling halves (AGMA sizes 1-7) are interchangeable with couplings of other manufacturers. MTT type are not interchangeable.
• Coupling halves are joined by special body fitting grade 8 bolts. Adapted nuts are used. While applying tightening torque, nuts rotate and bolts are kept fixed.
