Maintaining and Inspection of Hydraulic Cylinders

Hydraulic cylinders handle demanding roles across countless applications. Operators must follow a strict maintenance schedule and inspection plan.

The single best step for long life and peak performance: select the exact right cylinder for the job. Every time equipment comes in for routine maintenance or repair, crews must evaluate whether that cylinder truly fits the application.

Follow the tips below help cylinder identify potential issues and prevent unscheduled downtime:

1. 1. Ensure adequate filtration system for hydraulic fluid. Check for dirt or foreign materials in the fluid with regularly scheduled samples sent out for analysis. Inspect the filter for any clogs.
   2. Inspect the cylinder rod for signs of weakness or stress. A rough, bent, or scored rod will damage seals or allow for leaks. Inspect sealed area of the system components and fluid lines for evidence of leaks. Examine all lubricated areas and replenish as needed.
   3. Review Cylinder Tube for signs of ballooning and/or machine interference which can cause serious leaks, damage and even cylinder failure.
   4. Check for side loading, which if not corrected, can lead to misalignment, tube scoring, and bearing wear and damage beyond repair.
