Capacità basata sul disegno
Bushing Machining Parameters
The following ranges are practical production guidance, not universal drawing limits.
| Capacità | Metal Bushings | Engineering-Plastic Bushings |
|---|---|---|
| Tolleranza dimensionale tipica | ±0,01-0,02 mm | ±0.03–0.05 mm |
| Outside diameter | Ø 2–300 mm | Ø 2–300 mm |
| Typical turning length | Up to 500 mm | Up to 500 mm |
| Minimum bore | Ø2 mm | Ø 2–3 mm |
| Spessore minimo della parete | 0,5 mm | 1,0 mm |
| Typical machined roughness | Ra 0,8–3,2 μm | Ra 1,6-3,2 μm |
Final capability depends on material condition, wall thickness, length-to-diameter ratio, clamping and inspection method.
Produzione e controllo qualità
Dalla revisione dei disegni al collaudo finale
Machining and inspection are planned around the bore, outside diameter, length, fit and sliding surfaces.
Confirm fit, datums, wall thickness and functional surfaces.
Turn, bore, groove and finish features in the approved sequence.
Verify bore, OD, length, position and concentricity.
Confirm edges, finish, records and shipment protection.

Application Review
Choose the Bushing Around Its Working Conditions
A practical quotation starts with the interface and duty cycle—not only the inside and outside diameters.
Choose a Bushing When
- The housing or parent bore needs a replaceable wear surface.
- Rotary, linear or oscillating motion needs controlled friction.
- Maintenance cost should be reduced through replaceable components.
- Vibration, shock or alignment requires a defined interface.
Confirm Before Quotation
- Load direction, speed, duty cycle and service life.
- Mating-shaft material, hardness and surface condition.
- Lubrication, temperature, moisture and chemical exposure.
- Fit, clearance, quantity and inspection requirements.
