TUBE BEAM

551 818 50B TUBE BEAM is a critical dampening element, plain and simple. It’s designed to sit in there and take a beating, absorbing a huge amount of the shock and vibration that comes from drilling. Without it, you’d be transferring all that raw impact energy directly into the frame, the boom, or whatever heavy assembly it’s supporting. It helps keep things from rattling themselves loose and protects the more rigid structural components from fatigue cracks over time. It’s about managing those dynamic loads, keeping the whole setup a bit more stable and less prone to premature wear.

When this TUBE BEAM starts to wear out, you’ll definitely notice the difference. Usually, what happens is the rubber hardens, cracks, or starts to delaminate, losing its ability to absorb those impacts. You'll often hear increased noise – a new clunking or rattling, especially under load – and you might feel a noticeable increase in vibration through the machine. If it’s supporting something like a rock drill or a feed beam, you could even start seeing accelerated wear on the mounting points, maybe bolts coming loose more frequently, or even slight misalignment that wasn't there before. It’s a pretty clear indicator that the dampening effect is gone, and other parts are taking the brunt of it.

When it comes to maintenance, these rubber beams aren't usually a major headache to swap out, but don't just slap a new one in without a quick inspection. Always give the mounting points and the surrounding structure a good once-over for any signs of fatigue cracking or deformation. A common thing folks forget is to check the condition of the mounting hardware – bolts, washers, and any sleeves. If those are worn or corroded, you're just putting a new part onto a compromised connection, and it won't last as long. Make sure everything is clean and torqued to spec.
