Bore-to-OD Components
CNC Machined Bushings and Sleeves
Formexi machines bushings and sleeves where inside diameter, outside diameter, wall thickness, concentricity, fit and surface condition affect assembly or motion. Material and machining route are selected from load, speed, lubrication, temperature, corrosion and wear requirements.

Functional Requirements
- Press, transition or clearance fit
- ID-to-OD concentricity and wall uniformity
- Bearing or sliding surface roughness
- Flange face and shoulder relationships
- Lubrication grooves, ports or holes
- Material compatibility with shaft and housing

Material Choices
| Material direction | Potential reason | Boundary |
|---|---|---|
| Bronze/brass | Bearing, wear or machinability | Grade and lubrication determine performance |
| Steel/stainless | Strength and load | Corrosion, hardness and galling review |
| POM/nylon/PTFE/PEEK | Low friction, insulation or chemical needs | Creep, moisture and temperature movement |
Thin-Wall Distortion
Clamping and material removal can make thin sleeves oval or tapered. Process planning may use soft jaws, controlled clamping, staged ID/OD machining, stress relief or final grinding/honing where available. Measurement should reflect the free or assembled condition specified by the buyer.
Fits Must Be Defined Correctly
Provide mating shaft/housing size, fit system, operating temperature, lubrication and measurement condition. A nominal diameter without tolerance and fit does not define a functional bushing.
Inspection
Bore gauges, micrometers, plug gauges, indicators and surface measurement may be used according to the feature. Long or small bores may require special methods that must be confirmed before production.

Our Review Method for CNC Machined Bushings and Sleeves Requirements
The purchasing issue behind CNC Machined Bushings and Sleeves is that the buyer needs a supplier response tied to the actual part rather than a generic capability statement; as a result, a broad promise can leave geometry, material, quality, cost and delivery assumptions unresolved. Our response is to turns the drawing and purchase requirement into documented process, inspection and approval questions before price or production is confirmed. The objective is to protect assembly and validation schedules while reducing preventable scrap, rework and supplier-change risk.
For the CNC Machined Bushings and Sleeves buying decision, before we confirm price or delivery, the buyer should send the controlled drawing and model, material, quantities, critical requirements, finish, quality documents, target date, destination and confidentiality needs. If a requirement cannot yet be verified, we keep it as an open condition instead of presenting it as a guaranteed result.
Apply CNC Machined Bushings and Sleeves to the Buyer Decision
For CNC Machined Bushings and Sleeves, use the controlling 2D drawing and 3D model to define part number and revision, material and condition, quantity and annual demand, critical tolerances and GD&T, roughness, heat treatment, surface finish, inspection documents, packaging, delivery address and target date. Identify confidentiality restrictions and which DFM changes may be considered for this part.
Price and lead time can be confirmed only after geometry, material availability, programming, workholding, external processes, inspection effort, first-article approval and logistics are reviewed together.
Check the complete RFQ inputs before supplier comparison.
Review the Bushing as Part of the Fit
Send shaft, housing, load, speed, lubricant, temperature and fit information.
