ISO ADAPTER – 4X4 EXTENSION WITH BEARING (LONG MODEL)

(HIGH TORQUE TRANSMISSION – BEARING SUPPORTED – FOR ISO FLANGED PTO SYSTEMS)

This special type ISO 4x4 extension adapter with bearing provides both distance extension and bearing-supported rotational stability in the transition from PTO output to pump or cardan shaft connection. It is especially preferred in 4-bolt PTO flanges compliant with ISO 7653 standards when there is not enough clearance between the pump body and the vehicle chassis and in high-speed applications. Thanks to its bearing-supported structure, vibration is reduced, proper shaft support is provided, and shaft life is extended. It is generally used in tipper trucks, sweeper vehicles, vacuum trucks, and mobile hydraulic systems.
