Here at Callcott and Downey, we often come across recurring problems with certain hydraulic cylinders. Of course, we could simply repair the cylinder to OEM specification and send it back to the customer, but whenever possible, we like to go a step further and eliminate the problem entirely.
For a long time, we have been repairing R2900 lift cylinders, many of which have suffered similar failures. We decided to eliminate these issues, and produce a superior product to extend the service life of the cylinder and reduce customer costs.
Our R2900 SUPERLIFT cylinder benefits from several upgrades over the OEM equivalent, including a single piece forged rod. By forging the rod, we have significantly reduced the risk of snapping and cracking around the neck and the eye, failures that the original cylinder often encountered. We have also replaced the original cast gland with a stronger and far superior forged gland, to minimise the risk of cracking. Other upgrades include additional chrome on the rod, a forged base cap, upgraded high temp. seals and a high specification steel barrel.
BENEFITS OF FORGING
“Directional alignment through the forging process has been deliberately oriented in a direction requiring maximum strength. This also promotes ductility and resistance to impact and fatique.” University of Metallurgy
