Complete Cylinder Rebuilding
The Alexanders team disassembles, inspects, repairs, and rebuilds hydraulic cylinders to restore reliable operation and maximize service life.
Rod Repair & Replacement
Damaged or bent rods can cause seal failures and poor cylinder performance.
Alexanders machines replacement rods from induction-hardened chromed rod for exceptional durability and longer service life. To speed the repair process, Alexanders maintains an inventory of common rod sizes.
Seal Replacement
Worn or damaged seals are one of the most common causes of hydraulic cylinder failure. Leaking seals reduce efficiency and can damage equipment. Alexanders’ inventory includes an extensive assortment of the most common types and sizes.
Resealing and repacking a hydraulic cylinder involves completely disassembling the unit to replace its internal rubber and plastic seals, which naturally degrade over time. This routine maintenance restores the cylinder’s ability to hold hydraulic pressure, eliminates fluid leaks, and revives lifting power without the high cost of buying a brand-new unit.
Barrel Honing & Machining
Scored, worn or damaged barrels are restored using precision machining and honing techniques to improve performance and reliability. If the damage is extensive, new tubes can be machined and welded in place.
Welding, Fabrication and CNC Machining
Alexanders’ in-house welding and fabrication team allows for the repair of cracked components, and the CNC machine shop can manufacture replacement parts as needed.
