Custom Aluminum
Bronze Bushing Solutions
An aluminum bronze bushing is a sleeve, bearing, spacer, thrust part, wear ring, or threaded insert made for a specific mechanical interface. It can be supplied as a plain sleeve, flange, grooved bearing, split bushing, thrust washer, or custom machined part.
Performance depends on alloy, hardness, shaft, lubrication, load, speed, temperature, bore finish, clearance, wall thickness, and concentricity. CNCPioneer reviews the operating condition before machining so the part is built for wear life, serviceability, and stable production.

Why CNCPioneer for
Aluminum Bronze Bushings?
One production partner for alloy selection, bearing-bore control, wear and corrosion DFM, machining, inspection, and OEM documentation. Built for marine, valve, pump, mining, construction, hydraulic, aerospace, automotive, and industrial programs.
Material Selection for Wear and Load
C95400 suits general wear and marine service; C95500 adds strength; C95800 is common for cast-equivalent valve, pump, and marine programs; C63000 supports high-strength wrought parts. We compare alloy, hardness, load, speed, corrosion, temperature, machinability, and cost before quoting.
Bore, Clearance, and Concentricity Control
Running clearance, bore roundness, shaft finish, and axis alignment determine service life. We review shaft diameter, hardness, Ra, lubrication, load, speed, temperature, and fit. Targets can include ±0.010mm bore-to-OD concentricity, controlled roundness, ID size, and 0.010mm/25mm flange perpendicularity.
Flanged, Grooved, and Thrust Bushing DFM
Flanges spread load, grooves retain lubricant or release debris, and thrust washers handle axial movement. We check flange and shoulder geometry, wall thickness, thrust-face flatness, groove and oil-hole position, press fit, and replacement access before production.
Swiss CNC and MAZAK Custom Geometry
Small parts can be turned from bar with guide-bushing support. Larger sleeves, flanges, split bushings, valve seats, threads, cross holes, and multi-feature parts use MAZAK mill-turn or controlled secondary operations selected by size, stock condition, quantity, tolerance, and inspection.
Machining and Finishing Support
Tooling, coolant, chip evacuation, deburring, bore finishing, edges, and cleaning are matched to the alloy and geometry. Polishing, blasting, protective coating, laser marking, and special packaging are available while critical bearing surfaces remain protected.
OEM Documentation and Traceability
Material certificates, XRF, hardness, dimensional, bore, concentricity, surface-finish, C of C, PPAP Level 3, AS9102 FAIR, and lot records are available. Packaging can follow your warehouse or service-part process.

Materials
Materials for Aluminum
Bronze Bushings
Select cast, wrought, nickel aluminum bronze, or a specified copper alloy by load, speed, wear, seawater, corrosion, hardness, machining route, temperature, and volume.
C95400 Aluminum Bronze
C95400 balances strength, hardness, wear resistance, corrosion performance, and cost for bearing sleeves, valve parts, pumps, marine hardware, and heavy equipment. Stock condition, bore allowance, machining sequence, hardness, clearance, and final inspection are reviewed for each part.
C95500 Aluminum Bronze
C95500 adds strength and hardness for heavy load, impact, pressure, and high-cycle service in machinery, marine equipment, valves, pumps, and wear components. We confirm material condition, hardness, machining allowance, bore finish, tool wear, and shaft clearance before quoting.
C95800 Nickel Aluminum Bronze
C95800 nickel aluminum bronze supports demanding marine, seawater, valve, pump, and fluid applications. Cast or semi-finished stock can be machined into bushings, wear rings, seats, and flanges with attention to allowance, porosity, bore finish, hardness, stability, and documentation.
C63000 / C62300 Aluminum Bronze
C63000 and C62300 offer high strength, good wear behavior, and stable wrought properties for aerospace, automotive, industrial, marine, and high-load applications. Temper, hardness, grain direction, stock size, allowance, and final dimensions are reviewed.
Wrought Nickel Aluminum Bronze
For a combination of strength, seawater resistance, wear resistance, and repeatable wrought stock quality. We confirm designation, temper, hardness, environment, shaft, clearance, and finish before production, with material and hardness records available.
Special Aluminum Bronze and Copper Alloys
Drawings may specify a national standard, proprietary alloy, heat-treated condition, or special chemistry. We review supply, machining behavior, hardness, wear, corrosion, stability, and cost, with XRF, material certificates, hardness reports, and lot traceability available.
Surface Treatments & Finishing
Choose the finish by wear, friction, lubrication, corrosion, appearance, cleaning, and assembly needs. Critical bearing surfaces remain protected while dimensional change, edges, and inspection are controlled.
Precision Machined and Gauged Surfaces
Bore and thrust faces are controlled through boring, reaming, turning, deburring, roundness, concentricity, finish, and final size checks. Critical bores remain protected during handling and can be checked with calibrated gauges.
Polishing for Lower Friction and Controlled Ra
Polishing or fine finishing can improve sliding behavior, cleanability, and appearance. We confirm whether the bore, shaft, thrust face, or exterior needs treatment and verify that material removal does not change clearance, wall, or flange dimensions.
Bead Blast and Uniform Matte Finish
Bead blasting creates a consistent matte appearance for visible bushings, marine hardware, equipment covers, and industrial components. Media, pressure, masking, edges, and cleaning are controlled to preserve bore, sealing, and thread dimensions.
Deburring, Chamfering, and Lubrication Feature Control
Controlled deburring and chamfering protect shafts, oil holes, bore entries, grooves, cross holes, slots, and threads. Lead-ins and lubrication features are inspected so installation is smooth and service paths remain open.
Protective Oil, VCI, and Service-Part Packaging
Protective oil, sealed bags, sleeves, trays, or replacement-part kits can support storage and shipment. Bearing bores, thrust faces, threads, and flange seats are protected from impact and contamination, with labels matched to your warehouse process.
Laser Marking and Material Traceability
Part numbers, alloy IDs, lot codes, orientation marks, and replacement references can be marked with controlled location, depth, contrast, corrosion exposure, and cleanability, without affecting the bore, sealing face, or thread interface.
Our DFM confirms boring, finish, deburring, lubrication features, protective packaging, marking, surface measurement, and post-finish inspection for each program.

Aluminum Bronze Bushing FAQ
Answers to common questions about alloy selection, clearance, wear, marine service, inspection, and lead time.
Send a 2D drawing or STEP file with alloy, hardness or condition, ID, OD, length, flange or shoulder dimensions, groove and oil-hole details, finish, quantity, and packaging notes. Without a drawing, shaft diameter and hardness, housing fit, load, speed, lubrication, temperature, environment, duty cycle, and annual usage are enough to start.
C95400 is a common starting point for general wear, marine, valve, pump, and industrial bushings. C95500 adds strength and load; C95800 suits marine, seawater, valve, and pump service; C63000 and C62300 support high-strength wrought programs. DFM confirms the best match for load, speed, shaft, lubrication, hardness, corrosion, temperature, and budget.
Clearance depends on shaft diameter, hardness and finish, bushing ID, load, sliding or oscillating speed, lubrication, temperature, contamination, and thermal expansion. Too little can cause seizure; too much can increase vibration, leakage, and wear. DFM confirms bore size, finish, concentricity, and fit for the actual operating condition.
Simple prototypes typically take 5–8 business days after drawing approval and material availability. Large diameters, C95800, special hardness, cast stock, grooved or flanged geometry, tight bores, and detailed documentation may take 8–15 business days. Volume timing depends on material, cycle time, inspection, packaging, and quantity. Quotes arrive within 24 hours and DFM within 48 hours for most projects.
