Parker 4.00NLP94.00 Rodless Air Cylinder 4 in Bore 250 Psi

Product Description

The PARKER 4.00NLP94.00 is a double acting rodless air cylinder designed for linear motion applications in pneumatic systems. With a 4 inch bore and 4 inch stroke, it delivers consistent bidirectional force using compressed air. The aluminum body keeps weight manageable at 5.34 pounds while maintaining structural integrity under pressure. Maximum working pressure is 250 psi, and port connections are 3/8 NPT. Nitrile butadiene rubber (NBR) seals provide reliable performance across typical shop-air service conditions. This cylinder is installed by industrial maintenance technicians and automation specialists in manufacturing and process control environments.

This cylinder fits applications requiring compact rodless linear actuation where a traditional rod-style cylinder would create clearance conflicts. The 4 inch bore makes it suitable for moderate-force automation tasks such as shuttling, positioning, and material transfer on production lines. Mounting is via head or cap configuration, allowing flexibility in how the cylinder is oriented and secured to the machine frame. The 3/8 NPT ports accept standard pneumatic fittings used in most North American compressed-air systems.

Key Features

• Double acting design provides powered motion in both extend and retract directions
• 4 inch bore with 4 inch stroke for moderate-force, compact linear travel
• 250 psi maximum working pressure rated for standard shop-air and industrial pneumatic systems
• Aluminum body construction reduces overall weight while maintaining durability
• NBR seals offer reliable air retention across typical operating temperature ranges
• 3/4-16 rod thread size on female style end fitting for secure load attachment
• Head or cap mounting style provides flexible installation orientation

Compatibility

Designed as an OEM-style rodless air cylinder for use in industrial pneumatic linear motion systems requiring a 4 inch bore double acting configuration with 3/8 NPT porting and head or cap mount.

Installation Notes

Installation should be performed by a qualified maintenance technician or pneumatic systems specialist. Isolate and bleed all compressed air from the circuit before removing an existing cylinder or fitting the new unit. Ensure all NPT port connections are properly sealed with thread sealant rated for pneumatic service. Verify that supply pressure does not exceed the 250 psi maximum working pressure rating before returning the system to service.
