High-performance spare parts and drilling components for Sandvik rigs.
Bushing
The bushing, part 550 350 52, sits between two moving assemblies inside a Sandvik rock drill and is sized to a close working clearance with the shaft it supports, close enough that a slightly undersized replacement binds and a slightly oversized one introduces play immediately. That tight tolerance is why a visually similar bushing from a different position in the same drill is rarely a safe substitute. Measuring the clearance against the shaft it fits, rather than assuming a like-for-like swap, is the reliable way to confirm the reference before a rebuild goes back together.

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.

Cylinder HL1560
The cylinder, part 550 352 19, is the machined housing the piston strokes inside on a Sandvik HL1560 rock drill, and its bore finish is what the piston's own seal and guide surfaces are matched against. Scoring or ovality in that bore is rarely caused by the cylinder itself; it is usually the result of contamination or a worn piston running against it, which is why the piston and bushings are worth checking whenever a cylinder is condemned. Because the bore dimensions are specific to the HL1560, a cylinder from a similar-looking Sandvik model is not a safe substitute even where the outside dimensions appear close.

Gas Valve
The gas valve, part 3115 0262 00, is used to charge and check the nitrogen pressure in a Sandvik rock drill's accumulator, and the accuracy of that charge pressure has a direct effect on how the drill strikes. An accumulator charged even slightly outside specification changes the piston's stroke characteristics, which is felt as altered impact rather than diagnosed as a charging fault. Because the valve is only used periodically rather than continuously, a seized or leaking one often goes unnoticed until an accumulator is due to be checked, at which point the charging job cannot proceed without it.

Cap Nut
The cap nut, part 152 525 68, closes a threaded connection under internal pressure in a Sandvik rock drill, and it is the clamping force it holds, not just its shape, that keeps that connection sealed. A cap nut that has been reused through several rebuilds loses some of that clamping accuracy each time it is torqued down again, which is a slow way to develop a leak that looks unrelated to the fastener itself. Because it sits directly on a pressurised joint, fitting it correctly matters more than its low individual cost would suggest.

Distributor
The distributor, part 551 194 08, times the flow that drives percussion in a Sandvik rock drill, opening and closing internal passages in a fixed sequence so the piston is driven and returned on schedule. Wear here does not stop the drill; it shifts the timing slightly, and a percussion mechanism running even marginally out of time loses stroke energy long before anyone traces the cause back to this component. Because the symptom reads as reduced penetration rather than as a distributor fault, it is often the last component checked rather than the first, even though it is one of the more common causes.

Bushing
The bushing, part 550 350 49, is the smaller of the sleeve bearings fitted along this section of a Sandvik rock drill, supporting a reduced-diameter section of shaft where the surrounding components leave little room for a larger bearing surface. Its smaller area means unit loading is higher for the same duty, which is why it tends to reach its wear limit sooner than the larger bushings around it. A drill that has been apart before is worth checking here even if the larger bushings nearby still measure within tolerance, since this is often the first of the set to need renewal.

Bushing
The bushing, part 550 350 50, locates the piston centrally in the cylinder bore of a Sandvik hydraulic rock drill, and its job is concentricity rather than load-bearing in the way a rotation bushing works. Once it wears unevenly, the piston starts striking slightly off-axis, and the resulting side load shows up as accelerated wear on the piston and bore rather than on the bushing that actually caused it. Because the fault presents as bore or piston wear, this bushing is easy to overlook during diagnosis unless it is checked directly.

Assembly Kit
The assembly kit, part 550 065 21, bundles the seals, bushings and retaining rings needed for one stage of a Sandvik rock drill rebuild into a single reference, so a workshop does not have to cross-check a parts book line by line to find what one strip-down actually consumes. Ordering the loose items individually is where kits like this usually get missed, and it is also where a rebuild stalls waiting on the one small ring nobody thought to order. Because the components in the kit are matched to each other, fitting only part of it and reusing the rest defeats the purpose of buying it complete.

Shank Bushing
The shank bushing, part 550 358 24, supports the shank adapter at the point where percussion energy leaves the rock drill and enters the drill string, which makes it one of the most heavily loaded bushings in the machine. Clearance here does not stay constant under load; it opens gradually as the bushing wears, and the play it introduces is what starts hammering the shank and the chuck around it rather than the bushing alone. Because the wear it causes shows up in neighbouring components before it is obvious in the bushing itself, it is normally checked and renewed together with the shank and chuck at the same service rather than on its own. Perfomega quotes this Sandvik reference by part number and exports worldwide to mining, quarrying, and drilling contractors.
Percussion Kit
The percussion kit, part BG005 501 96, groups the seals, bushings and small wear parts a Sandvik rock drill's percussion mechanism needs for one overhaul into a single reference, covering the items around the piston and distributor rather than the piston and distributor themselves. Ordering these piecemeal against a parts book is where a percussion overhaul most often loses time, usually over one or two small items that were not obviously part of the job until the mechanism was already open. Because the kit is scoped to a single overhaul rather than to a whole drill, confirming it against the specific mechanism being rebuilt avoids ordering a kit sized for the wrong generation of drill.

Driver
The driver, part 550 347 86, carries rotational drive between the rotation motor and the chuck inside a Sandvik rock drill, sitting in a chain where every joint's backlash adds to the next one's. A driver with worn splines does not slip outright; it hammers on every direction change instead, and that hammering is what damages the mating components around it rather than the driver in isolation. Because it works as part of a chain rather than alone, it is usually renewed alongside the components it drives during a rotation unit overhaul rather than replaced by itself.
