Piston
Hydraulic energy becomes impact energy at the piston, which strikes the shank many times per second for the whole of a working shift. No component in the drill works harder. Dimensional accuracy and surface condition both matter, because a piston running marginally out of specification wastes energy and transfers damage to whatever it strikes. Replacement is normally planned against drilling hours and carried out alongside the parts the piston works directly against, so the assembly goes back together with matched wear. Given the value of the item, confirming the reference in the machine's parts manual before ordering is time well spent. Send the Sandvik part number to Stalroc for a quotation and export lead time.
Piston Stabilizer
Side loading is unavoidable in a percussion machine, and the piston stabilizer is what resists it, keeping the striking element aligned through every stroke. Once that alignment drifts, impact energy stops arriving squarely and begins to punish the components the piston works against rather than the rock. Because the resulting symptoms — slower penetration, heavier vibration, uneven shank wear — could each have several causes, stabilizers tend to be replaced on schedule during overhaul rather than diagnosed in isolation. Cross-checking the reference against the machine's parts manual before ordering avoids the most common sourcing error in this group. Stalroc quotes this Sandvik part against its manufacturer number and ships worldwide, so it can be included in a planned rebuild consignment.
Bearing Assembly
Rotating elements inside a rock drill run on bearing assemblies built to take thrust, radial load and percussion shock simultaneously. The impact component is what separates this duty from ordinary industrial bearing service and why replacement intervals follow drilling hours rather than generic life calculations. Assemblies are supplied complete because their internal parts are matched and wear as a set; mixing elements between units rarely ends well. Where a rotation unit is being stripped anyway, quoting the neighbouring components at the same time avoids a second shipment. Stalroc supplies this Sandvik reference against its part number and exports to mining, tunnelling and quarrying sites worldwide, quoting from the manufacturer reference so the order matches the machine.
Piston Stabilizer
A piston stabilizer keeps the striking element running true through its stroke, holding alignment against the side loads that percussion inevitably generates. Alignment is what determines whether impact energy arrives squarely at the shank or is partly wasted, and a stabilizer that has worn allows the piston to work slightly off axis with consequences downstream. The symptoms are indirect: falling penetration rate, unusual wear on the shank adapter, more vibration through the feed. Because those signs point at several possible causes, stabilizers are usually renewed during scheduled overhaul rather than diagnosed individually. Stalroc quotes this Sandvik part by number with worldwide export.
Bearing Assembly
A bearing assembly supports rotating elements under combined thrust and radial loading while percussion shock passes through the same structure. That duty is unusual: bearings in most machinery never see impact of this kind, which is why rock drill bearing life is measured against drilling conditions rather than catalogue figures alone. Assemblies are supplied as matched units because the components inside them are meant to wear together. Substituting individual elements between assemblies is a false economy that usually shortens the life of the whole unit. Stalroc quotes this Sandvik reference by part number and can price related rotation components at the same time for a complete overhaul.
Bushing
Wear inside a rock drill is deliberately concentrated on components like this bushing, which are designed to be renewed at intervals. The surrounding housing is expensive and slow to replace; the bushing is neither. Allowing one to run past its wear limit inverts that economy, transferring clearance and load into parts nobody wants to be changing in the field. Most operations replace on accumulated drilling hours rather than waiting for symptoms, since by the time looseness is obvious the damage has usually spread. Keeping one on the shelf costs far less than the downtime of sourcing it urgently. Stalroc quotes this Sandvik part by number and exports worldwide, so replacements can be staged in advance of a planned service window rather than chased afterwards.
Flushing Device
The flushing device directs air or water through the drill string to clear cuttings from the hole. Flushing is easy to overlook until it degrades: cuttings that are not evacuated grind against the bit and rod, raising wear rates across the whole string and slowing penetration well before anyone connects the symptom to its cause. Because poor flushing damages consumables faster than it damages itself, the economic case for keeping this component in good order rests on what it protects. Checking flushing performance during routine service costs little and protects the parts that do wear quickly. Stalroc supplies this Sandvik reference against its manufacturer number, with OEM and aftermarket options quoted where both are available, and ships to drilling operations worldwide.
Bushing
This bushing serves as a sacrificial bearing surface within the drill, absorbing wear that would otherwise fall on the housing around it. Percussion shock, rotation and abrasive flushing debris all act on it at once, which is why bushings are treated as scheduled consumables rather than permanent components in any well-run maintenance plan. The practical difficulty is that bushings of similar appearance are not interchangeable between drill models or generations. Quoting against the Sandvik part number, checked in the machine's own parts manual, removes that risk entirely. Stalroc confirms availability by reference before quoting and exports worldwide, which suits sites holding a modest rotating stock.
Bolt
Fasteners in a percussion machine live a harder life than their appearance suggests. Every impact cycle tries to loosen them, and a bolt that backs off slightly allows movement between clamped faces, which then wear and make the joint impossible to tighten properly again. Correct replacement rather than reuse is the cheap insurance here. Workshops that reuse fasteners through several rebuilds tend to discover the cost later, in fretted mating surfaces on far more expensive castings. Ordering the correct Sandvik reference keeps the joint behaving as the machine's designers intended. Stalroc quotes this part by number alongside the larger components it secures, so a rebuild kit can be assembled in a single enquiry.
Piston
The piston, part 302 969 08, delivers repeated impact through a Sandvik percussion mechanism, so unlike a static hydraulic piston it has to survive shock loading on every stroke rather than just steady pressure. Fatigue cracking under that kind of repeated impact develops from the inside out, which means a piston nearing the end of its life can look completely sound right up until sudden failure. Impact energy that isn't transferred cleanly into the tool being driven reflects back into the piston itself, so misalignment elsewhere in the mechanism tends to shorten piston life even though the piston is not where the underlying problem is. Stalroc quotes this Sandvik reference by part number and exports worldwide to mining, quarrying, and drilling contractors.
Rotation Shaft
The rotation shaft carries turning force through the drill's rotation unit under continuous torque, with percussion shock passing through it at the same time. That combination is demanding: a shaft that is fatigued but not yet broken can still cause misalignment that wears bearings and bushings around it well before anyone suspects the shaft itself. Inspection during scheduled overhauls is the practical safeguard, since failure in service usually means an unplanned strip-down and a rig standing idle while parts are located. Recording the reference from the machine's parts manual at that point saves repeating the search later. Stalroc quotes this Sandvik part by its manufacturer number and exports worldwide, which helps when a rotation unit rebuild is being assembled from several references at once.
Gear Wheel
A gear wheel transmits drive through the rotation mechanism, converting motor output into the controlled turning force the drill string needs. Tooth condition determines whether that transfer stays smooth or begins to shock-load the components on either side of it. Damage rarely stays local — a failing gear takes its neighbours with it. Gear wheels are usually replaced as part of a rotation unit overhaul rather than singly, and it is worth quoting the mating components at the same time so the unit goes back together with matched wear. Waiting until tooth damage is visible in service tends to convert a planned overhaul into an emergency one. Stalroc supplies this Sandvik reference against its part number with worldwide export, and can quote related rotation parts together so the rebuild arrives as one consignment.
