Logan Clutch Component

Logan SAE PTO 400 Series Direct Drive PTO Clutch

Logan SAE PTO 400 direct drive PTO clutch: 400 ft-lb (524 Nm) rated torque, 180 HP, 2400 RPM, bi-rotation, low 80–100 psi actuation, SAE B or C output options.

Description

The Logan SAE PTO 400 Series is a direct drive PTO clutch designed to actuate at lower pressures (80–100 psi) than the PTO-250, PTO-500 and PTO-750 series. Torque capacity is proportional to operating pressure; running at the lowest pressure that transmits the required torque keeps the clutch cooler and extends bearing life.
