Metric Bronze Bushing Size Chart Guide
Metric bronze bushings are typically specified in millimeters by inside diameter, outside diameter, and length. For sourcing and production, the nominal size is only the starting point. The final quote also depends on fit, clearance, material, lubrication, quantity, and whether the bushing is standard or custom machined.
This page is prepared for a future downloadable metric size chart. Once your standard size table is ready, it can be added here as a PDF or spreadsheet for buyers to download.
How Metric Bushing Dimensions Are Organized
| Dimension | Common meaning |
|---|---|
| ID | Nominal shaft size or finished bore |
| OD | Housing bore size or press-fit diameter |
| Length | Bearing length and available installation space |
| Wall thickness | Difference between OD and ID, important for strength and groove design |
| Flange size | Flange OD and thickness if the part locates axially or carries thrust |
Standards and Fit References
For metric shaft and hole fits, engineers commonly reference ISO 286 limits and fits. ISO 286 uses a letter-number format such as H7 or g6:
- Uppercase letters describe hole tolerance zones.
- Lowercase letters describe shaft tolerance zones.
- The number describes the IT tolerance grade.
In practical terms, a metric bronze bushing project should define the housing fit, shaft clearance, and finished bore condition instead of only giving a nominal millimeter size.
Common Metric Size Searches
Buyers often search for sizes like “10mm bronze bushing,” “20mm bronze bushing,” or “30mm sleeve bearing.” Those searches usually mean the shaft size is known, but the housing bore, length, material, and running clearance still need confirmation.
For a clean RFQ, include:
- Shaft diameter in millimeters.
- Housing bore in millimeters.
- Bushing length.
- Sleeve, flanged, thrust washer, or custom part style.
- Material requirement, such as C93200 / SAE 660, C95400 aluminum bronze, or SAE 841 sintered bronze.
- Groove, oil hole, or self-lubricating requirement.
Downloadable Metric Size Chart
The downloadable metric bushing chart will be added here after your standard size data is finalized. The chart should list common ID, OD, length, wall thickness, and product style options, with a note that final tolerance and clearance must be confirmed by application.
Standard Size vs. Made-to-Print Metric Bushings
Use a standard metric bushing when the shaft, housing, and length match a normal catalog size and the application does not require special grooves or documentation.
Use a made-to-print bushing when the drawing calls for special length, nonstandard wall thickness, flange details, oil grooves, graphite plugs, tight inspection, or a specific alloy.
