Ko te LONGLOOD RACH Series Single Acting Aluminum Hollow Plunger Hydraulic Cylinders are designed for applications requiring both high-force pulling and pushing in a lightweight, portable package. Featuring a center-hole hollow plunger, single-acting spring return, a 700 aukati (10,000 Psi) operating pressure, these cylinders are ideal for tensioning, cable pulling, shaft removal, bearing extraction, bolt stretching, and heavy lifting.
Hangaia mai teitei-kaha konumohe konumohe, the RACH Series is significantly lighter than comparable steel cylinders, making it easy to transport and ideal for field service, hangahanga, maina, bridge maintenance, hangahanga ki uta, me te tiaki ahumahi.
Available in capacities from 20 ki 150 tārewa me 50 ki 250 mm nga whiu, the RACH Series delivers outstanding performance while reducing operator fatigue and improving productivity.
The center-hole plunger allows the cylinder to be used for both pushing and pulling applications. It is ideal for tensioning rods, pulling shafts, removing bearings, extracting sleeves, and prestressing operations.
Manufactured from high-strength aerospace-grade aluminum alloy, the cylinder offers exceptional durability while significantly reducing overall weight compared with steel hydraulic cylinders.
Hydraulic pressure extends the piston while an internal heavy-duty spring automatically retracts it after pressure is released, improving efficiency and reducing operating time.
The precision-machined hollow piston features a hard chrome-plated surface for excellent wear resistance, parenga waikura, me te mahi maeneene.
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, position, 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 aukati (10,000 Psi) to deliver powerful hydraulic performance.
