Bushing Machining Parameters
The following ranges are practical production guidance, not universal drawing limits.
| 能力 | Metal Bushings | Engineering-Plastic Bushings |
|---|---|---|
| 代表的な寸法公差 | ±0.01-0.02 mm | ±0.03–0.05 mm |
| 外径 | Ø2～300 mm | Ø2～300 mm |
| Typical turning length | Up to 500 mm | Up to 500 mm |
| Minimum bore | Ø2 mm | 直径2～3 mm |
| 最小壁厚 | 0.5 mm | 1.0 mm |
| 代表的な機械加工面粗さ | 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.
製造および検査
図面審査から最終検査まで
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.

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.
