Frequently Asked Questions

Q: What are oil-impregnated powder metallurgy bushings and how do they work?

A: Powder metallurgy bushings are sintered metal components made by compressing and heating metal powder (in this case copper or a copper-iron blend) to form a porous structure. This porosity allows oil to be absorbed and retained within the bushing itself. As the shaft rotates, heat and pressure cause the oil to seep out, creating a continuous self-lubricating film that reduces friction and wear without the need for external re-lubrication during normal operation.

Q: What applications are these 8×16×11mm bushings suitable for?

A: These bushings are designed for a broad range of light-duty applications including juicers and small kitchen appliances, automotive assemblies, power tools, electric motors, fans, and other equipment requiring a smooth-running guide sleeve for an 8mm shaft. Always verify that the inner diameter, outer diameter, and length match your specific shaft and housing dimensions before installation.

Q: Are the dimensions exact, and how should I measure for a replacement?

A: The nominal dimensions are 8mm (inner diameter) × 16mm (outer diameter) × 11mm (length). Please allow for a 2–3% manufacturing tolerance. When selecting a replacement bushing, measure your shaft's outer diameter (should match the bushing's 8mm inner bore), the housing's inner diameter (should match the 16mm outer diameter), and the required length (11mm). Using calipers for accurate measurement is recommended.
