ZF ISO ADAPTER – FROM 4 CONNECTIONS TO SPLINED FLANGED

(FOR ZF PTO OUTPUT – TRANSITION FROM ISO 4-HOLE TO SPLINED FLANGE – OPTIMIZED FOR TORQUE TRANSMISSION)

This special type ZF ISO adapter is designed to convert the 4-hole ISO PTO output found in ZF brand transmissions directly into a splined flanged pump or cardan shaft connection. It is especially used in equipment connected to PTO outputs in ZF 6S, 9S, 12AS, and 16S series transmissions. The adapter converts the ISO 7653 compliant 4-bolt flange into a splined shaft output compliant with DIN 5462 or similar standards, providing direct torque transmission. It is widely preferred in vacuum pump, hydraulic pump, and PTO-driven equipment applications.
