O 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. Presentando a center-hole hollow plunger, single-acting spring return, e 700 bar (10,000 PSI) presión de operación, these cylinders are ideal for tensioning, cable pulling, shaft removal, bearing extraction, bolt stretching, and heavy lifting.
Fabricado a partir de aliaxe de aluminio de alta resistencia, the RACH Series is significantly lighter than comparable steel cylinders, making it easy to transport and ideal for field service, construción, minería, bridge maintenance, enxeñaría offshore, e mantemento industrial.
Dispoñible en capacidades desde 20 a 150 toneladas con 50 a 250 mm trazos, 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, protección anticorrosiva, e un funcionamento suave.
The hard-coated aluminum body provides excellent protection against corrosion and harsh working environments, making it suitable for indoor, outdoor, e aplicacións mariñas.
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, posición, 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 bar (10,000 PSI) to deliver powerful hydraulic performance.
