Bushing
Sliding and rotating surfaces inside drilling equipment run against bushings, which accept wear so the surrounding housing does not. That sacrificial function is the entire point: renewing a bushing is quick and inexpensive, whereas machining or replacing the component behind it is neither, and the maintenance economy depends on staying ahead of that line. Once clearance opens beyond the wear limit, load transfers outward into parts with long lead times. Replacement on drilling hours rather than on symptoms is the standard approach for this reason. Ordering by reference rather than appearance matters, because bushings that look alike are often not interchangeable. Stalroc quotes this Sandvik part by number and exports worldwide, which suits sites holding a small rotating stock.
Shaft
Torque reaches its destination through shafts like this one, working under continuous rotational load with machine vibration superimposed on it. The duty is unforgiving because the failure mode is gradual: bearing and bushing wear around a shaft that is no longer running true often gets replaced repeatedly before the shaft itself is suspected. Inspection during planned overhaul catches that pattern earlier and more cheaply than waiting for a breakdown. Where several rotation references are being renewed together, quoting them as one enquiry keeps freight and documentation simple. Stalroc supplies this Sandvik part against its manufacturer number and exports worldwide to drilling operations.
Frame
The frame carries the loads a drilling machine generates and transmits them into the structure that supports it. Everything mounted to it depends on its geometry staying true: alignment that has shifted through impact damage or fatigue puts components out of position, and the resulting wear appears somewhere other than the frame itself. Structural parts are usually inspected rather than routinely replaced, with distortion being harder to spot and more consequential than visible cracking. Where a frame is being renewed, checking what mounts to it at the same time is sensible. Stalroc quotes this Sandvik reference by part number and exports worldwide to mining, tunnelling and quarrying sites.
Shaft
Rotational load passes through this shaft under torque, with the vibration and shock of a working drilling machine acting on it throughout. Fatigue in those conditions builds quietly; a shaft running slightly out of true can wear the bearings and bushings around it for a long time while still appearing serviceable to inspection. That is why assessment during scheduled overhaul is worth more than reactive replacement, since in-service failure normally means an unplanned strip-down with the machine standing. Recording the reference at that point saves repeating the search later. Where several shafts and bearings are renewed together, one enquiry covering them all keeps the paperwork proportionate. Stalroc sources this Sandvik reference against its part number for export worldwide.
Wearing Piece
A wearing piece is fitted where abrasion is expected and accepted, taking damage that would otherwise fall on structure behind it. The economics are deliberate: this item is designed to be consumed and renewed, while what it shields is not. Leaving one in service past its limit simply moves the wear somewhere far more expensive. Because replacement is anticipated, these parts suit on-site stock and scheduled renewal rather than reactive ordering. Checking condition during routine service takes little time and keeps the decision in the maintenance window rather than the breakdown one. Stalroc quotes this Sandvik reference by part number and ships worldwide to mining and tunnelling operations.
Plate
Load is carried and distributed across a structure by plates like this, tying components together so forces spread rather than concentrate. On mobile drilling equipment they also take impact from the working environment: rock fall, knocks during tramming, and the constant vibration that finds every weakness in a fabricated assembly over time. Damage tends to be visible, which makes inspection straightforward, but distortion is easier to miss than cracking and matters just as much for the alignment of whatever mounts to it. Renewing rather than straightening is usually the sounder call. Where a plate is being renewed, checking the fasteners and mating components at the same time avoids a repeat visit.

Flange Assembly
A flange assembly forms a bolted joint between components that must stay concentric and sealed under load. On drilling equipment those joints carry vibration continuously, so flange faces and fasteners work harder than the same arrangement would in static plant, and a joint that has begun to move rarely recovers without attention. Supplied as an assembly, the reference brings its parts together already matched rather than gathered separately, which shortens the rebuild and removes the risk of a missing item stopping work on the day. Stalroc quotes this Sandvik part against its manufacturer number, confirms availability before committing, and exports worldwide to mining, tunnelling and quarrying operations.
Hose Support Assembly
Routing and restraining hydraulic lines is the job of assemblies like this one, holding them so they are not chafing, stretching or vibrating against structure while the machine works. Unsupported hoses fail early and unpredictably, and a burst line means lost fluid, contamination risk and a machine stopped in a position that is rarely convenient for repair. Supports are easy to overlook precisely because they are not the components that fail — they are the components whose absence causes failures elsewhere. Checking them during routine service is inexpensive insurance against a hose replacement mid-shift.

Bearing Bushing
A bearing bushing combines a locating function with a renewable running surface, supporting movement while accepting the wear that would otherwise reach the housing. In a machine subject to percussion, rotation and abrasive contamination at once, that sacrificial role is what keeps major castings serviceable across multiple rebuild cycles. The practical caution is that visually similar bushings differ between drill models and generations, so appearance is not a safe guide. Ordering against the Sandvik reference, checked in the machine's own documentation, removes that risk. Where a rebuild needs several such references at once, quoting them together keeps freight and paperwork to a single consignment. Stalroc confirms availability by part number before quoting and ships worldwide to drilling contractors.
Bearing
Rotating and oscillating movement under load is supported by bearings such as this, and in drilling equipment they do so with shock loading superimposed on ordinary duty. That combination is what sets rock drill bearing service apart and why intervals are set against machine hours and ground conditions rather than standard catalogue expectations. Renewing a bearing against worn mating surfaces rarely delivers the life the new part was capable of, so the surrounding components are normally assessed at the same time. Quoting them together also keeps the consignment to one shipment. Confirming the reference in the machine's documentation before ordering avoids the mismatches that similar sizes invite. Stalroc supplies this Sandvik part against its number and exports worldwide to mining, tunnelling and quarrying sites.
Bushing
Bearing and sliding surfaces inside drilling equipment are protected by bushings like this one, which take wear onto a replaceable item instead of the housing behind it. The arrangement is deliberate: the bushing is cheap and quick to change, the housing is neither, and the whole maintenance economy depends on renewing the former before the latter is affected. Running past the wear limit reverses that logic, transferring clearance and load into components with long lead times. Most operations therefore replace on drilling hours rather than on symptoms. Since bushings of similar appearance are not always interchangeable between models, the manufacturer reference remains the dependable way to order. Stalroc quotes this Sandvik part by number and exports worldwide, which suits sites keeping a modest buffer stock.
Lock Nut
A lock nut secures a threaded joint against the vibration and impact loading that would otherwise loosen it over a working shift. In percussion machinery this is not a formality: the constant shock means threaded connections are actively being worked loose whenever the machine is running, and the locking function is what stands against that. Once a joint has been allowed to move, the mating faces wear and correct clamping becomes difficult to restore without renewing more than the fastener. Fitting the specified reference rather than a general-purpose equivalent is the straightforward safeguard.
