Parker 3.25TEF4MAU14A04.00 Rodless Air Cylinder 3-1/4in Bore

Product Description

The PARKER 3.25TEF4MAU14A04.00 is a double acting rodless air cylinder designed for linear motion control in pneumatic systems. With a 3-1/4 inch bore and 4 inch stroke, it delivers consistent push and pull force from a compact profile that suits tight machine envelopes. The aluminum body keeps weight manageable at 9.8 pounds while holding up to 250 psi maximum working pressure. Nitrile butadiene rubber seals maintain air containment across the operating range. Licensed pneumatic technicians and machine builders typically install this cylinder in automated equipment, material handling systems, and production machinery where space constraints rule out conventional rod-style cylinders.

This cylinder fits applications in both light industrial and medium-duty automation environments. The rodless design allows the full stroke length to be used within the cylinder body footprint, making it well suited for pick-and-place assemblies, clamping fixtures, and linear transfer units. The basic mount style allows direct attachment to machine frames or subplates. Port size is 1/2 NPTF, compatible with standard shop-air plumbing at typical industrial supply pressures up to 250 psi. Overall assembled length is 8-1/4 inches with an overall assembled width of 3-3/4 inches.

Key Features

• Double acting operation provides controlled force in both extend and retract directions
• 3-1/4 inch bore and 4 inch stroke deliver substantial linear force output within a compact envelope
• Aluminum body construction reduces overall system weight
• Nitrile butadiene rubber seals provide reliable air retention across operating pressures
• 1/2 NPTF port threads into standard pneumatic fittings without adapters
• Basic mount style simplifies integration into custom machine frames and subplates

Compatibility

Designed as an OEM-style replacement or direct-fit component for pneumatic automation systems requiring a double acting rodless air cylinder with a 3-1/4 inch bore, 4 inch stroke, and 1/2 NPTF porting in a basic mount configuration.

Installation Notes

Installation should be performed by a qualified pneumatic technician or machine builder familiar with compressed air system safety practices. Depressurize and lock out the air supply before removing or installing any pneumatic cylinder. Confirm all port connections are sealed with appropriate thread sealant rated for compressed air service before pressurizing the system. Verify that supply pressure does not exceed the 250 psi maximum working pressure rating of this cylinder.
