Custom Bushings for Motion, Support and Protection
Drawing-based bushings for rotating, sliding and locating applications. Select the material, fit and finish for your load, speed and service environment.
What Is a Bushing?
A bushing protects the parent part while guiding motion, managing friction, absorbing vibration or sealing a working gap.
Wear Protection
Provides a replaceable wear surface for shafts and bores.
Motion Control
Supports rotary, linear and oscillating movement.
Vibration Control
Elastomer options isolate shock, noise and structure-borne vibration.
Alignment and Sealing
Maintains fit, position and selected sealing functions.
When Is a Bushing the Right Choice?
Choose a bushing when the base component should be protected, service access matters, or the design needs a defined friction and compliance point.
Protect the Parent Part
Use a replaceable wear element instead of wearing the housing or precision bore.
Manage Motion
Match clearance, hardness and friction to rotary, sliding or oscillating loads.
Reduce Service Cost
Replace the bushing rather than the complete arm, bracket or housing.
Fit the Environment
Choose metal, plastic, rubber or composite construction for temperature, media and lubrication.
Bushing Types for Different Loads and Fits
Select the structure from the load direction, installation method, available space, service environment, and replacement requirements.
Sleeve Bushings
Function: Simple cylindrical support for rotary or oscillating shafts.
Select when: You need radial support and a compact replaceable wear surface.
Flanged Bushings
Function: An axial shoulder locates the part and helps resist push-out.
Select when: Axial positioning or a positive installation stop is required.
Threaded Bushings
Function: Threads combine positioning, fastening, or adjustment in one part.
Select when: The bushing also needs to secure or adjust an assembly.
Drill Guide Bushings
Function: Provides hard, accurate guidance for tooling and repeatable drilling.
Select when: Hole location, repeatability, and tool guidance are critical.
Self-Lubricating Bushings
Function: Supports low-friction movement where grease access is limited.
Select when: The interface is dry, clean, difficult to lubricate, or maintenance-sensitive.
Rubber & Hydraulic Bushings
Function: Adds compliance and damping for vibration-control assemblies.
Select when: Shock isolation and controlled stiffness matter more than sliding wear performance.

Capability values are indicative. Submit your drawing, material, tolerance, quantity and operating conditions for a project-specific review.
Lower Cost Without Losing Fit
Use the right material, tolerance and process for the working conditions—then confirm that the supplier can make and inspect the part consistently.
Keep Machining Cost Under Control
Cost falls when the part is designed around its functional fit instead of unnecessary precision or complex production.
- Reuse standard diameters, lengths and common fit classes where possible.
- Use conventional turning or milling for simple geometry and suitable quantities.
- Apply tight tolerances only to features that affect motion, sealing or assembly.
- Balance material price, tooling cost, service life and replacement frequency.
Choose a Reliable Bushing Manufacturer
A capable supplier reviews the full application, not only the dimensions shown on the drawing.
- Confirm drawing review, fit recommendations and material traceability when needed.
- Check machining, finishing and inspection capability before placing repeat orders.
- Share load, speed, temperature, media, quantity and delivery requirements early.
- Request project-specific inspection records for critical dimensions or batches.
