Ultra-High Torque Hydraulic Cylinder Repair System for Heavy-Duty Applications
Large hydraulic cylinders used in mining, construction, steel production, heavy equipment, marine applications and other demanding industries require more than conventional workshop equipment.
They need a repair system capable of handling extreme loads, large components and high piston nut torque safely and precisely.
The Seide Large Hydraulic Cylinder Repair Bench combines cylinder disassembly, component handling, reassembly and hydraulic pressure testing in one integrated system. Designed for heavy-duty hydraulic cylinder service operations, the system provides a more controlled and efficient alternative to conventional repair methods.
Over 250,000 Nm of Ultra-High Torque
One of the key advantages of the Seide hydraulic cylinder repair bench is its ultra-high torque capability exceeding 250,000 Nm.
Depending on the configuration, the hydraulic torque system can be supplied with torque capacities including:
- 65,000 Nm
- 130,000 Nm
- 250,000 Nm
- 300,000 Nm
The 300,000 Nm configuration is designed for applications where extremely high piston nut loosening and tightening torque is required.
This makes the system particularly suitable for large hydraulic cylinders used on heavy mining equipment, large construction machinery, steel mill equipment and other high-load industrial applications.
Large Hydraulic Cylinder Disassembly Machine
Disassembling a large hydraulic cylinder manually can require significant labor, lifting equipment and multiple handling operations.
The Seide repair bench is engineered to centralize these operations on one heavy-duty workstation.
Its full-length bench structure provides a rigid working platform for large cylinders, while adjustable clamping and positioning equipment helps secure cylinder tubes and piston rods during the repair process.
Heavy-Duty Bench Construction
The system is designed for large and heavy hydraulic cylinders with fixture capacities of up to 6,000 kg.
Key features include:
- Full-length heavy-duty bench construction
- High structural rigidity
- Adjustable sliding plates
- Height-adjustable chain clamping tools
- Secure cylinder and piston rod positioning
- Flexible tooling for different cylinder configurations
- Large usable working area
- Integrated oil collection system
The robust construction is intended to support demanding hydraulic cylinder repair operations while improving workshop safety and repeatability.
Hydraulic Cylinder Assembly Machine
After inspection and repair, the same system can be used for cylinder reassembly.
The high-torque hydraulic drive can operate in reverse for controlled piston nut installation. Torque values can be set according to the required OEM specifications, helping technicians achieve consistent tightening results.
With an optional PLC-controlled HMI system, operators can manage machine functions from a centralized interface and preset torque values for standardized repair procedures.
This creates a repeatable workflow for hydraulic cylinder overhaul operations.
Integrated Hydraulic Cylinder Pressure Testing
A hydraulic cylinder repair is not complete until the repaired cylinder has been tested.
The Seide system integrates hydraulic pressure testing into the repair bench, eliminating the need to transfer the cylinder to a separate test station.
Standard pressure testing is available up to 300 bar, with an optional configuration for testing up to 500 bar.
The system can also provide:
- Digital pressure test visualization
- Test result recording and data export
- Optional linear encoder
- Stroke length measurement
- Automatic multi-point testing
- Digital data logging
- Optional LAN, Wi-Fi or GSM data transfer
This allows repaired hydraulic cylinders to be inspected and tested before being returned to service.
Designed for One-Operator Hydraulic Cylinder Repair
The integrated workstation concept is designed to reduce unnecessary material handling during the repair process.
Cylinder positioning, disassembly, reassembly and testing can be performed within the same working environment, helping reduce the need for additional lifting and handling equipment.
The result is a more organized repair workflow with fewer handling operations and improved operator control.
Advanced Piston Nut Removal Technology
Large piston nuts can be one of the most difficult components to remove during hydraulic cylinder overhaul.
The Seide system uses a hydraulic high-torque nut removal mechanism designed for demanding applications.
An optional rotating nut removal table provides access to piston nuts without requiring the piston rod or cylinder tube to be rotated.
Hex socket adapters are available up to 345 mm, supporting a wide range of large piston nut dimensions.
Hydraulic Torque Control
The high-torque system provides controlled torque during both removal and assembly.
Torque values can be configured through the HMI according to the required repair procedure, helping service workshops establish standardized and repeatable tightening processes.
For extreme applications, the system can reach 300,000 Nm of torque, providing more than 250,000 Nm of ultra-high torque capacity for demanding large-cylinder applications.
Hydraulic Cylinder Repair Workflow
The Seide Large Hydraulic Cylinder Repair Bench is designed around a complete repair workflow.
- Cylinder Positioning
The hydraulic cylinder is positioned horizontally on the repair bench and secured using adjustable chain clamps and sliding plates.
The system accommodates different cylinder sizes and configurations within its rated fixture capacity.
- Cylinder Disassembly
The piston nut is removed using the hydraulic high-torque nut removal system.
The piston rod can then be extracted using a 7-ton pulling force, while dedicated tooling assists with internal component removal.
- Cleaning and Inspection
After disassembly, components can be cleaned and inspected for:
- Wear
- Surface damage
- Deformation
- Corrosion
- Seal damage
- Mechanical defects
- Repair and Component Replacement
Damaged components can be repaired or replaced before reassembly.
Dedicated tooling can also support seal installation and component handling.
- Reassembly
Components are installed in reverse order.
The hydraulic torque system provides controlled piston nut tightening, while the HMI can be used to set the required torque and system limits.
- Pressure Testing
The completed hydraulic cylinder is connected to the integrated test system.
Leakage and performance testing can then be performed before the cylinder is released for service.
- Digital Test Records
Test information can be displayed and digitally recorded.
Optional communication features allow test data to be transferred through LAN, Wi-Fi or GSM, providing additional traceability for professional hydraulic cylinder repair facilities.
Full-Length Oil Collection System
Hydraulic cylinder disassembly can release residual hydraulic oil.
The integrated full-length oil collection tray captures oil during the repair process and transfers it to a dedicated waste oil reservoir.
This helps maintain a cleaner workshop environment, reduce cleanup time and improve overall workplace organization.
Modular Hydraulic Cylinder Repair Equipment
The Seide repair bench is built around a modular concept.
Additional tooling can be added according to the requirements of the service workshop. Tooling can also be purchased individually, while custom tool ends can be developed for special cylinder designs.
This allows the repair bench to evolve as the workshop's hydraulic cylinder repair requirements increase.
