The Q6P03 is a pneumatic rotary union for transferring air or vacuum across a rotating interface. This model has 18 mm bore, 86 mm OD, 164 mm body length, and is part of the Q series, which also includes gas-electric versions that carry electrical channels in the same unit.
Typical applications: pneumatic chucks and collets, vacuum suction heads on rotating arms, air cylinders on indexing tables, and coolant or air supply to rotating tooling.
Selection notes: pure pneumatic units are rated −90 kPa to 1 MPa at up to 300 rpm; gas-electric combined units are rated −80 kPa to 0.8 MPa at up to 250 rpm. Choose the combined version when the same joint must carry both fluid and power or signals. Life expectancy for the Q series is 20 million revolutions.
GUREN machines and assembles rotary unions in-house and pressure-tests each unit before delivery.
Custom circuit counts, lead lengths, connector types and mounting flanges are quoted on request, and in-house machining keeps lead times short for both standard and modified units.
