Compatible rock drill components for Sandvik — 131 parts listed
Cylinder
The cylinder, part 550 047 84, forms the pressure boundary and piston bore of a Sandvik rock drill, carrying both the hydraulic porting that drives percussion and the structural load the drill's housing depends on. Because the bore is a precision surface rather than just a structural wall, damage to it is rarely repaired on site; a scored or worn bore is normally a replacement decision rather than a machining one. Cylinder wear is usually driven by whatever is running inside it rather than by the cylinder itself, so a worn piston or contaminated fluid is worth investigating before the new cylinder is put into the same conditions that damaged the last one.

Rotation Bushing Assy
The rotation bushing assembly, part 550 526 12, supplies the bushing together with its retaining ring and mating spacer as a matched set rather than as a single sleeve, which is the detail that separates it from ordering a rotation bushing on its own. Fitting a new bushing against a worn retaining ring or spacer rarely delivers the clearance the new bushing was machined to, so buying the set keeps the fit as designed rather than as approximated from whatever is already on the shelf. Where only the loose bushing is actually needed, the assembly still confirms that the surrounding components are being renewed to the same standard rather than reused by default.

Bearing
The bearing, part 552 250 91, runs under the combined vibration and shock loading a Sandvik rock drill puts through its rotating components, and a bearing failing under that duty usually gives a warning before it seizes: rising noise or a patch of heat felt through the housing during a routine check. Both are worth treating as an early warning rather than something to monitor, since a rock drill bearing under this kind of loading offers little margin between the first symptom and outright failure. Renewing on that early symptom, rather than waiting for it to worsen, is what keeps the repair to the bearing itself rather than the shaft and housing it runs in.

Seal Kit
The seal kit, part 551 732 85, bundles the seals for one Sandvik rock drill assembly matched to that assembly's bore sizes and fluid duty, which matters because seals of the same apparent dimensions are not always cut from the same compound or durometer. Mixing seals sourced individually rather than as this kit risks a set that fits on the bench but wears unevenly once it is back under pressure. Buying the kit also means the less obvious items, the small back-up rings and wipers that are easy to leave off an individual order, arrive with the rest rather than being discovered missing mid-rebuild.

Rotation Bushing
The rotation bushing, part 550 253 61, carries the torque of the rotation drive inside a Sandvik rock drill, and as it wears the drive train it supports starts to develop backlash before the wear is measurable any other way. That backlash is usually heard rather than seen: a knock or chatter on rotation reversal that gets dismissed as normal machine noise until it is compared against a drill running a fresh bushing. Catching it at the chatter stage, rather than waiting for it to affect penetration rate, is what keeps the repair to a bushing rather than the components it drives.

Rear Cylinder
The rear cylinder, part 097 055 08, carries the return-line porting that feeds fluid back through a Sandvik rock drill's percussion circuit, and that porting is specific enough to the drill generation it was designed for that a rear cylinder from an earlier or later model rarely lines up correctly even when the outside dimensions look close. Fitting a mismatched reference here tends to show up as an internal leak path rather than as a part that visibly does not fit. Confirming the reference against the machine's own parts manual before ordering is the reliable way to avoid that mismatch, particularly on a rig that has had components mixed across a model change.

Cylinder Rear
The rear cylinder, part 153 602 08, closes the back end of the stroke in a Sandvik rock drill and interfaces directly with the back head, so it carries both the piston's return-stroke impact and the porting that feeds the percussion circuit at that end. Wear here tends to concentrate at the point where the piston reverses direction, which is a narrower band of the bore than the piston's full travel covers. Because that wear band is localised rather than spread along the bore, a rear cylinder can need renewal well before a straightedge check anywhere else in the assembly would suggest it.

Pin
The pin, part 154 020 08, locates two components in a Sandvik rock drill against each other so they index correctly every time the assembly is closed up, doing a positioning job rather than carrying a pivoting load the way a linkage pin does. If it is left out or fitted worn during a rebuild, the parts it locates can go back together slightly out of alignment without anything visibly wrong at the joint itself. Because the resulting misalignment is easy to miss on reassembly and hard to diagnose afterwards, checking this pin against its reference whenever the assembly is opened is worth the small cost of renewing it.

Pin
The pin, part 154 122 98, retains a component axially inside a Sandvik rock drill against the vibration the machine generates continuously, holding position rather than carrying rotating or pivoting load. A retaining pin that has worked loose does not usually fall out outright; it backs off gradually and lets the component it holds creep out of position over repeated cycles. That slow creep is what makes retaining pins worth checking on a schedule rather than waiting for something to visibly shift, since by the time movement is obvious the component has usually already been running out of position for a while. Perfomega quotes this Sandvik reference by part number and exports worldwide to mining, quarrying, and drilling contractors.
Piston
The piston, part 153 669 48, transfers hydraulic pressure into the impact that drives a Sandvik rock drill's percussion mechanism, and its outer surface finish is what its seal depends on to hold pressure through tens of thousands of cycles. A surface that has lost its finish, even without visible scoring, lets pressure bypass the seal gradually rather than all at once, so output falls off before any single fault becomes obvious. Because that kind of wear is progressive, checking piston condition against drilling hours rather than waiting for a clear symptom is the more reliable approach. Perfomega quotes this Sandvik reference by part number and exports worldwide to mining, quarrying, and drilling contractors.
Bearing
The bearing, part 550 356 04, supports rotating load inside a Sandvik rock drill's rotation unit under the vibration and shock loading that percussion drilling superimposes on ordinary rotating duty. That extra loading is why bearing intervals on this kind of equipment are tracked against machine hours and ground conditions rather than against general catalogue ratings, which assume steadier service than a drill actually sees. A bearing renewed against worn mating surfaces rarely reaches the life the new part is capable of, so the shaft and housing it runs in are normally checked at the same time rather than after the fact. Perfomega quotes this Sandvik reference by part number and exports worldwide to mining, quarrying, and drilling contractors.
Seal Housing
The seal housing, part 152 623 38, sits at a point in a Sandvik rock drill where it holds back flushing water or air as well as hydraulic fluid, so its job is keeping two different kinds of contamination out rather than containing a single fluid. A housing that has worn even slightly at this position lets flushing debris track inward along a path the seal was never designed to block on its own. Because that ingress point is easy to miss during a routine seal change, checking the housing bore whenever the seals here are renewed is worth the extra few minutes.
