{imgAlt}Most Cat® Cylinders and Rods (new and remanufactured) are induction-hardened and inertia-welded. The resulting superior strength and dent resistance deliver longer component life and reduced risk of system contamination. Cat hydraulic cylinders and rods are designed to allow for a variety of service and repair options.

Hydraulic Cylinders and Rods

Cat Cylinders feature an innovative sealing system that absorbs pressure spikes, withstands side loading, and guards against contaminant entry better than competitive designs.

Reduce Potential for System Contamination

  • Cat new and reman rod-eyes are attached to the cylinder rod through inertial welding that allows for a continuous bond vs. a standard arc weld.
  • Cat Seals are designed and manufactured to meet stringent specifications.
  • Cat new and reman rods are induction hardened to provide a surface that resists denting and scratching, thus reducing potential for system contamination.
  • The cylinder barrel surface can be honed to correct damage, extend seal life and reduce the potential for contamination. Caterpillar recommends a light hone at time of seal replacement.
