Excavator Bushings

Shop aftermarket excavator bushings by inner diameter, equipment make, or installation position. Compare dimensions, lubrication features, and application details to find the right replacement for your machine.

Shop by Inner Diameter

Choose the bore size, then check outer diameter and length on the product page.

Shop by Equipment Make

Check the listed model, part number, and installation position before ordering.

Shop by Installation Position

Find bushings listed for bucket, linkage, boom, and arm joints.

Check all three dimensions: ID × OD × Length. For example, 40 × 50 × 50 mm means 40 mm inner diameter, 50 mm outer diameter, and 50 mm length. Inner diameter alone does not confirm compatibility. Verify the required fit tolerances, lubrication features, and application.

Excavator Bushings for Bucket and Pin Connections

Explore replacement excavator bushings at Fab Heavy Parts. This collection includes bucket bushings, pin bushings, sleeve bearings, and selected application-specific bushings for excavators and related heavy equipment.

Bushings are used in mechanical joints to provide a bearing surface between connected components. They are commonly found in excavator bucket and linkage assemblies, where pins and bushings work together to accommodate movement.

Our collection covers a range of sizes, designs, and listed equipment applications, helping customers identify replacement components for worn or damaged joints.

Excavator Bucket Bushings and Sleeve Options

Available products include steel bucket bushings in different inside diameters, outside diameters, and lengths.

Examples of listed dimensions include 40 × 50 × 50 mm, 45 × 55 × 40 mm, 65 × 80 × 70 mm, and 70 × 85 × 60 mm. These measurements represent individual product options, not interchangeable sizes.

The collection also includes flanged bushings and selected pin bushing kits. Different designs may be intended for different joint configurations, so the original component's dimensions and installation requirements should be checked carefully.

Replacement Bushings for Different Equipment Applications

Our collection includes products listed for several equipment brands and model families.

Examples include:

  • Komatsu excavators: Bushing 205-70-73180, listed for selected PC120, PC160, PC200, PC220, and PC228 applications.

  • Kobelco excavators: Sleeve bushings LS12B01035P1 and LS12B01046P1, listed for selected SK480LC and SK485-series applications.

  • Kubota excavators: Bushing RD451-66370, listed for KX040-4, KX057-4, U48-4, and U55-4 models.

  • Bobcat equipment: Pin bushing kit references 7101078 and 6805453, listed for selected compact equipment models.

These examples reflect individual product listings and do not establish universal compatibility across each machine series.

Choosing the Right Excavator Bushing

Before ordering, compare the original bushing's part number, inside diameter (ID), outside diameter (OD), length, and structural design with the replacement listing.

Also inspect the mating pin and surrounding joint components. Wear or damage in these areas may affect the suitability of a replacement bushing.

Confirm the equipment model, serial number, installation position, and original part specifications before selecting your replacement.

Frequently Asked Questions

How do I find the correct bushing for my excavator bucket?

Start by checking the original bushing's part number and dimensions, including inside diameter, outside diameter, and length. We also recommend confirming your excavator model, serial number, and the exact bucket or linkage position. Bushings used in different joints may have different specifications, even on the same machine.

Can I choose an excavator bushing based on its dimensions alone?

Not always. Although matching the inside diameter, outside diameter, and length is important, bushings may also differ in design, material specifications, lubrication features, and installation requirements. We recommend checking the original part number and applicable equipment parts documentation whenever possible.

What's the difference between a straight bushing and a flanged bushing?

A straight bushing has a generally cylindrical profile, while a flanged bushing includes an extended rim at one end. The flange may provide axial positioning or a bearing surface, depending on the assembly. These designs are not automatically interchangeable, so we recommend matching the original bushing configuration.

What should I do if my old excavator bushing has no readable part number?

You can use your excavator's make, model, serial number, and the location of the bushing to help identify a replacement. Accurate measurements and clear photos of the original component may also help narrow down possible options. If the bushing is heavily worn or deformed, verify the required dimensions against the equipment's parts or service documentation rather than relying on worn measurements alone.

Should I inspect the bucket pin when replacing a worn bushing?

Yes. We recommend inspecting the mating pin, bushing housing, and surrounding linkage components for wear, deformation, or damage before installation. A worn pin or damaged housing can affect the fit and operation of a replacement bushing. Follow the equipment manufacturer's service instructions to determine whether additional components need repair or replacement.
