Hydraulic & Pneumatic Component Repair
Hydraulic and pneumatic systems depend on consistent pressure, clean fluid or air flow and properly functioning components. Leaks, contamination, worn seals, damaged internal surfaces and pressure loss can affect machine performance, clamping force, motion control and production reliability. NNG Industries provides inspection, repair, rebuilding, exchange and replacement support for hydraulic and pneumatic components used in CNC machines, workholding systems and industrial equipment. The goal is to identify the failed component and determine whether repair, rebuilding, exchange or replacement is the most practical path.
Hydraulic Component Repair
Inspection, repair and rebuilding support for hydraulic components used in industrial and machine-tool applications.
Pneumatic & Air Component Repair
Service support for air-operated components and pneumatic systems.
Seal & Packing Replacement
Inspection and replacement of seals, O-rings, packings and other common wear components.
Leak & Pressure Testing
Testing support for pressure loss, internal leakage and inconsistent system performance.
Precision Machining & Restoration
Machining and restoration support for worn shafts, housings, bores and related components.
Exchange & Replacement Support
Exchange-unit evaluation and replacement sourcing when repair is not the best option.
Receive → Disassemble → Inspect → Approve → Rebuild → Test
Find the Failed Component Before Replacing the System
Pressure loss or inconsistent motion may appear to be one problem while the actual cause involves seals, valves, actuators, contamination or internal wear. NNG evaluates the component and operating conditions so the service recommendation reflects the actual failure rather than the most obvious symptom.
Restore pressure, movement and dependable operation.
Repair support based on the component and application.
