Exactly as described

The product description was accurate regarding the dimensions and material. The flange thickness is consistent across the different sizes I tested. Highly recommended for maintenance tasks.

Smooth operation immediately

These bushings run very smoothly right out of the box. The self-lubricating property works well for my conveyor belt application. No squeaking or binding after two weeks of continuous use.

Perfect fit for my lathe project

The variety of sizes in this kit is excellent. I needed a specific 12mm flanged bushing for a repair on my old lathe, and it fit perfectly. The oil-impregnated feature means I don't have to worry about constant greasing.

Reliable standard parts

Used these to replace worn-out plastic bearings in a garden tool upgrade. The copper material is much more durable. The washer integration saves time during assembly. Would buy again.

Good quality, great value

Solid copper construction. The flange provides good stability against axial movement. Only giving 4 stars because the smallest sizes are a bit delicate, but overall a great purchase for general mechanical work.

Essential for hobbyists

As someone who builds small electric motors and RC cars, having this range of inner diameters from 1mm up to 30mm is a lifesaver. The shoulder step design makes installation very straightforward.

5 FAQ

Q: Is the flange removable or is it one piece?

A: The flange and the sleeve are manufactured as a single integrated piece using powder metallurgy. The flange cannot be removed; it is designed to provide axial location and act as a thrust washer.

Q: Do I need to add oil before installing these?

A: No, these bushings come pre-impregnated with oil. They are self-lubricating and ready to install. However, adding a drop of light machine oil on the shaft before insertion can help with initial break-in.

Q: Are these bushings suitable for high-speed applications?

A: These oil-impregnated copper bushings are best suited for low to medium speed applications. For very high speeds, additional external lubrication or a different bearing type might be required.

Q: Can I cut these to a custom length if needed?

A: Yes, since they are made of sintered copper, they can be cut to a custom length using a fine-tooth saw or a cutting wheel. Please ensure you deburr the edges after cutting to prevent wear on the shaft.

Q: What is the maximum load capacity for the 20mm size?

A: The load capacity varies based on the specific wall thickness and length chosen. Generally, our powder metallurgy bushings support moderate radial loads. For precise engineering calculations, please refer to the detailed spec sheet provided in the download section.
