PROTECCIN

BG 005 650 03A PROTECCIN is typically a sacrificial wear plate, designed to take the brunt of the abuse on a feed beam or a similar sliding assembly. Its main job is to keep the more expensive, structural components from getting chewed up by the drill string, chain, or whatever else is moving along it. Think of it as the first line of defense, absorbing the friction and impact that would otherwise wear down the main beam or housing. It’s there so you replace a relatively simple plate instead of having to weld up or replace a whole feed frame, which is a much bigger headache and cost.

When this PROTECCIN plate starts getting thin or cracks, that's when you begin to see problems. Usually what happens is the main feed beam itself starts showing wear marks, sometimes deep grooves. You might even hear a new kind of grinding or squealing noise during feeding, especially under load. If the wear is uneven, you could end up with the drill string or feed carriage binding up a bit, or not tracking straight. That uneven wear can also put extra stress on other components, like the feed chain or rollers, leading to premature failure there too. It's a clear sign that the sacrificial layer has done its job and is now gone, leaving the core structure exposed.

Replacing these isn't usually a complicated job, but you really want to make sure you clean up the mounting surface properly before you bolt the new one on. Any grit or old debris left behind can create high spots, leading to uneven wear on the new plate or even cracking it prematurely. Also, don't forget to check the fasteners; sometimes the old ones are stretched or corroded, and you definitely want fresh hardware to hold that new PROTECCIN in place securely. It's a small detail, but it makes a difference in how long the new one lasts.
