55050828 drive bushing: exact fit for Sandvik HLX 5 and Tamrock drifters

55050828 drive bushing slips into the drivetrain of Sandvik HFX 5T, HLX 5, HLX 5T, and RDX 5 drifters. It’s machined from a tough copper alloy, not generic brass, so it handles the hammering and twist of daily drilling without chewing up the splines too fast. If your old bushing rattles or the splines look polished to death, this one drops right in—same dimensions as the OEM part (550 508 28). No shimming, no filing, just grease it and go.

FAQ
FAQ
Which drifters does the 55050828 fit?
It’s a direct match for Sandvik HFX 5T, HLX 5, HLX 5T, and RDX 5. It’ll also work on older Tamrock rigs that call for part 55050828—just check your parts book or the number stamped on the old bushing.
Is this a genuine Sandvik part or an aftermarket copy?
It’s an OEM-spec replacement, not a genuine Sandvik box. We machine it to the same drawings—same spline tolerance, same copper alloy, same hardness. You get the fit and life without the genuine price tag.
How do I know this bushing will fit?
Pull the old one and check the number—55050828 or 550 508 28 should be stamped on it. If the number’s worn off, snap a photo of your drifter data plate and send it over. We’ll confirm compatibility before you order.
How long does this bushing last in normal rock drilling?
Depends on the ground, your greasing schedule, and how hard the drifter’s being pushed. With daily lube and no misalignment, you should see several hundred hours before the splines need attention. Keep an eye on it during bit changes—catch the wear early, and you’ll save the shaft.
When can you ship it?
These are stocked. Once you confirm the order, it’s usually out the door in 1–3 working days. If you need an ETA to your door, ask for a quote with your postcode and we’ll give you real-time shipping options.
