Large Hydraulic Cylinder Repair Bench | Disassembly, Assembly & Testing in One System
Seide Large Hydraulic Cylinder Repair Bench
Disassembly, Assembly and Pressure Testing in One Integrated System
Large hydraulic cylinders used in mining, construction, steel mills, marine and heavy industry require specialized repair equipment to ensure safe handling, precise assembly and reliable performance testing.
The Seide Large Hydraulic Cylinder Repair Bench is designed as a complete solution, combining disassembly, reassembly and pressure testing in a single modular workstation.
This all-in-one concept significantly improves operator safety, repair accuracy and workshop efficiency, while reducing total operating costs.
Hydraulic Cylinder Disassembly Machine for Large Cylinders
Disassembling large and heavy hydraulic cylinders is a demanding task that requires high structural strength, precise control and advanced safety features. Seide’s system is engineered specifically for these challenges.
Robust Full-Length Bench Design
Full-length heavy-duty bench construction
Designed for large and heavy cylinders up to 6000 kg fixture capacity
Extended usable working area allows additional repair operations on the same bench
High structural rigidity increases machine lifetime and operator safety
Sliding Plates & Height-Adjustable Chain Clamping Tools
Secure positioning of cylinder tubes and piston rods
Adjustable to a common tool center height
Maximum flexibility for different cylinder designs and configurations
Optional PLC-Controlled HMI Interface
Centralized control of all bench functions
Pre-setting of piston nut torque values
Integrated safety warnings and system limits
Ideal for standardized OEM repair procedures
Integrated Hydraulic Cylinder Pressure Testing Function
The Seide repair bench is not only a disassembly and assembly workstation—it also includes an integrated pressure test system.
Standard pressure testing up to 300 bar
Optional high-pressure testing up to 500 bar
Digital visualization and data export of test results
Optional linear encoder for:
Stroke length measurement
Automatic multi-point test protocols
This ensures that every repaired cylinder meets OEM specifications before returning to service.
True “Single Operator” Concept
Seide’s system is designed for maximum operational safety with one operator:
Reduced handling risks
Controlled movements during disassembly and reassembly
Optimized workflow without additional lifting equipment
This is a key advantage compared to conventional multi-station repair setups.
