Cylinder Remanufacturing
Swanson is a quality-certified worldwide supplier of remanufactured hydraulic cylinders.
With extensive engineering capabilities and decades of hands-on experience, Swanson leads the industry in restoring severely damaged hydraulic cylinders to prime working condition at a lower cost. Our global support system is well-positioned to take all types and sizes of worn, abused hydraulic cylinders and return the units to original equipment manufacturer specifications, or “like new” condition, at a cost that compares favorably to "new" cylinder replacement.
Specialized Machinery To Restore Severely Damaged Cylinders
Swanson houses the specialized machinery needed to remanufacture cylinders to OEM specifications:
- Conventional and CNC machine tools
- 33-inch diameter by 30-foot-long horizontal power hone
- 30-foot cylinder assembly machine
- Laser processing and welding technologies
- Proven testing facilities, including cylinder load testing by a 500-ton computerized test unit
Our World Class Remanufacturing Process Includes:
- Complete disassembly and inspection of all components
- Verification of components using the most recent OEM specifications
- Remanufacture component per approved specifications
- Thorough cleaning of each component
- Induction hardening for increased strength and wear resistance of hydraulic rods, rolls and pins
- Submerged arc welding to build up damaged components or total welding to build up excessively worn surfaces as part of the remanufacturing process
- Reassembly and testing components at normal working pressures to ensure OEM-caliber performance
All cylinder remanufacturing is performed in-house at Swanson’s state-of-the-art facilities:
- Single Acting
- Double Acting
- Welded Rod Cylinders
- Telescopic Cylinders
- Threaded or Bolted Head
- Long Stroke / Large Bore
- Position Feedback
- ISO-9001:2015
- Controlled Environment for Testing and Assembly
- Test equipment oil cleanliness maintained to 16/13 (ISO 4406) or better
- Every Cylinder is Pressure and Function Tested Before Shipment
- Certified Welders and Qualified Weld Procedures
Heavy industrial applications expose hydraulic cylinders to harsh, intensive conditions, resulting in severe wear that impacts performance. Replacing compromised cylinders with new units can be costly.

Benefits of
Remanufacturing vs Buying New
- Proper disposal of used parts
- Less energy consumed than in new product manufacturing process
- Carbon footprint reduced as current equipment is repaired and enhanced for continued use
- Resurface capabilities via laser technology revamp corroded or worn hydraulic cylinders
- Components repaired and remanufactured to industry standards at a lower cost
- Use OEM and remanufactured replacement parts”
Remanufacturing Processes
Industrial Chrome Plating
To enhance the mechanical and physical properties of hydraulic cylinder components, such as rods and internal cylinder tubes.
Laser Cladding
To resurface worn or damaged cylinders, rolls and pistons to prime working condition. Our workstations can accommodate a 1-48” diameter range, components up to 80’ feet in length, and a maximum weight of 40,000 lbs.
Friction Welding
A low-cost alternative for:
- Rod Assembly: bar to eye or three-piece rods made from tube to reduce weight, or
- Cylinder Body Fabrication: joining gland rings to tubes or welding end caps to tubes
Induction Hardening
For increased strength, wear resistance, and impact resistance of hydraulic rods, rolls and pins.
Submerged Arc Welding
Allows for the joining of thicker materials and weld metal overlay for dimensional restoration and the application of corrosion resistance/hard surface coatings.
