PISTON ROD MACHINING
The 552 201 64B PISTON ROD MACHINING is the working end of a hydraulic cylinder, turning fluid pressure into the linear force needed for boom or feed movement. It handles constant stress, so inspect it regularly. Replacing a worn one ensures your rig keeps operating smoothly and precisely.

Full Technical Description
552 201 64B PISTON ROD MACHINING is what actually takes the hydraulic pressure inside a cylinder and turns it into linear movement. Think of it as the muscle that pushes or pulls the load – whether it's extending a boom, tilting a feed, or even driving a drill string component. It’s constantly moving, dealing with significant forces, and it’s gotta be tough to handle all that work day in and day out on a rig.
When this rod starts showing its age, you’ll usually notice it in the cylinder's performance. Scratches, nicks, or even just worn chrome on the rod surface are bad news. What happens is, that damage lets hydraulic fluid bypass the piston seal, causing internal leakage. You’ll see the cylinder drift, meaning it won’t hold its position – a boom might slowly sag, or a feed cylinder won't maintain its pressure. Sometimes, you even get a noticeable 'judder' or inconsistent movement as the system tries to compensate for that lost pressure.
Look, when you're swapping one of these out, don't just slap the new one in. Always take a good look at the cylinder barrel itself for any scoring or damage that might have happened if the old rod was bent or really worn. And here’s a common one folks forget: always replace *all* the seals in that cylinder – the piston seal, rod seal, and wiper. It’s just good practice, saves you from doing the job twice, and makes sure the new rod isn’t compromised by old, hardened seals.
