The Pneumo-hydraulic Portable Pin Press Rockforce RF-B1339 75t Capacity is a mobile press designed for industrial and workshop use where controlled high-force pressing is required. It uses a pneumatic actuator to drive a hydraulic system, delivering up to 75 tonnes of pressing force for tasks such as pressing, extracting and installing pins, bushings and bearings. The unit is built for field service and maintenance work, offering portability combined with precise force control suitable for heavy-duty assembly and repair tasks.
Advantages
This portable pin press combines the speed and convenience of pneumatic actuation with the high force and control of hydraulic systems, enabling accurate and repeatable pressing operations. Its compact, mobile design allows technicians to perform on-site maintenance without moving large components to a stationary press. The controlled force application reduces the risk of damage to components and improves operator safety during extraction and installation operations.
Suitable for
- Pressing and installing pins, bushings and bearings in heavy machinery
- Extracting seized or worn components in maintenance and repair
- On-site assembly and disassembly tasks where a portable high-force press is needed
- Workshops and mobile service teams performing vehicle or industrial equipment repairs
When it may not be suitable
This press is intended for applications that require high pressing force and controlled hydraulic movement; it may be excessive for small-scale or delicate precision assembly where lower forces and finer control are needed. It is not intended to replace specialised low-force bench presses used for delicate electronics or micromechanical work.
Key specifications
- Maximum pressing force: 75 tonnes
- Operation: pneumo-hydraulic (pneumatic drive with hydraulic output)
- Design: portable / mobile press for field and workshop use
- Main applications: pressing, extracting and installing pins, bushings and bearings
- Control: regulated hydraulic force for controlled pressing
How to use
Set the press on a stable surface or secure it to the workpiece area using appropriate supports. Connect the pneumatic supply according to site air pressure and quality requirements, then position the press head over the pin, bushing or bearing to be worked on. Adjust the hydraulic pressure control to the required force and operate the pneumatic actuator to perform the pressing or extraction action. Monitor alignment throughout the operation to avoid uneven loading and stop immediately if any abnormal resistance or movement occurs. After use, relieve system pressure and follow routine maintenance checks such as inspecting hoses, fittings and seals.
What to consider before purchase
- Required maximum pressing force for your applications (up to 75 t)
- Availability and specifications of compressed air supply on site
- Physical access and space for using a portable press on the workpiece
- Compatibility with the diameters and types of pins, bushings and bearings you will service
Usage recommendations
Use appropriate fixtures and supports to ensure even load distribution and correct alignment; follow safety procedures for pneumatic and hydraulic systems, wear suitable protective equipment, and perform pre-use inspections of all hoses and connections to maintain reliable operation and reduce risk of component damage.
