Bushing Types for Different Loads and Fits
A bushing forms a replaceable interface between moving parts. Select the structure from load direction, installation method, available space, lubrication and replacement needs.
Sleeve Bushings
Compact radial support and a replaceable wear surface for shafts.
Flanged Bushings
Adds an axial locating shoulder and a positive installation stop.
Threaded Bushings
Combines positioning, fastening or adjustment in one component.
Drill Guide Bushings
Hard, accurate guidance for repeatable drilling and tooling location.
Self-Lubricating Bushings
Low-friction motion where grease access or maintenance is limited.
Rubber & Hydraulic Bushings
Compliance and damping for vibration, shock and controlled stiffness.

Drawing-Based Capability
Bushing Machining Parameters
The following ranges are practical production guidance, not universal drawing limits.
| Capability | Metal Bushings | Engineering-Plastic Bushings |
|---|---|---|
| Typical dimensional tolerance | ±0.01–0.02 mm | ±0.03–0.05 mm |
| Outside diameter | Ø2–300 mm | Ø2–300 mm |
| Typical turning length | Up to 500 mm | Up to 500 mm |
| Minimum bore | Ø2 mm | Ø2–3 mm |
| Minimum wall | 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.
Manufacturing and Inspection
From Drawing Review to Final Inspection
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.
