Baltimore Hydraulics offers Free Pickup & Delivery services for all your hydraulic components.

If your system is down and you have the capability of removing the defective component, we will repair it back to fully operational condition. All repairs are 100% tested and guaranteed for one year.

Cylinder Repairs
Our Cylinder Shop provides you with cost effective, quality repairs to all types of hydraulic and pneumatic cylinders. All rebuilds are 100% flow, pressure, and operationally tested. Hard parts are machined in-house and seal selections are made to provide the best performance for each application.

Our STANDARD PROCESS guarantees a quality repair every time.

  • Honing: All cylinder bores are honed to remove small nicks and burrs as well as provide the surface finish required for the type of seals being installed.

  • Polishing: All cylinder rods are polished to remove small nicks and burrs and provide a smooth, damage free surface for proper sealing.

  • Tolerances: Once the honing and polishing processes are complete, all parts are measured and checked for proper fit and tolerance.

  • Re-Chroming: Most cylinder rods, and some cylinder bores are chrome plated. If the chromed surfaces of these parts are found to be damaged, the first approach is to repair the affected area if small enough. The next step is to grind and prep the entire surface for re-chroming, and if the damage is severe a new part will be machined from plated material.

  • Bearings: All soft material wear bands and bearings are automatically replaced. Bronze and other soft metal bearings are machined new as normal wear usually leaves these parts out of tolerance.

  • Machining & Welding: Any broken, worn, or defective parts are fabricated new in our Machine & Weld Shops.

  • Assembly: Once all parts are renewed or reconditioned your cylinder is assembled by experienced personnel.

  • Testing: All component repairs are 100% tested at the appropriate pressure & flow.

  • Replacements: If all else fails, we offer a full range of standard and custom cylinders in welded and tie rod designs. These cylinders are available in inch and metric sizes as well as various pressure rages and materials. If it’s a special, we will design and custom build your cylinder to order.
