The hard-coated aluminum body provides excellent protection against corrosion and harsh working environments, making it suitable for indoor, outdoor, and marine applications.
Heavy-duty composite bearings minimize friction, improve side-load resistance, and extend service life.
A built-in stop ring prevents over-extension of the piston and enhances operational safety.
The aluminum construction allows operators to easily transport, موضع, and install the cylinder in difficult working environments.
The hollow plunger design allows use with threaded rods, puller systems, tensioning equipment, and other hydraulic accessories.
Engineered for reliable operation at 700 حاجِز (10,000 رطل لكل بوصة مربعة) to deliver powerful hydraulic performance.
