Case Studies

Background

Customer required a quick turnaround on a rebuild of a long stroke cylinder but could not source the packing kits in a timely fashion. The equipment was sitting idle and production was down.

Root Cause

Cylinder operates in a tough and rugged environment, and is impacted by significant side and shock loading that leads to premature failure.

Goal

Provide a turn-key kit for ease of use by maintenance that extends maintenance interval >6 months.
