Powder Metallurgy Bushings
PM bushings for high-volume industrial, automotive and mechanical applications — controlled porosity enables oil-impregnated self-lubricating, low-friction, maintenance-free operation.
- Materials
- PM alloy (oil-impregnated or dry)
- Features
- Controlled porosity for self-lubrication, high wear resistance, low friction coefficient, customizable shapes/flanges/wall thicknesses, consistent performance across large batches
- Application
- Electric motors and automotive actuators, household and office equipment (pumps, fans), industrial automation systems, aerospace and defense precision rotation assemblies, high-volume manufacturing.
Frequently Asked Questions
What materials and process are used for Powder Metallurgy Bushings?
Powder Metallurgy Bushings is made from PM alloy (oil-impregnated or dry) and is formed by MIM/PM (metal injection molding / powder metallurgy) near-net-shape and sintered to a relative density of ≥ 98%, which keeps mechanical properties close to wrought material.
What tolerances can Powder Metallurgy Bushings hold?
Typical as-sintered dimensional tolerance is ±0.3–0.5% of the dimension. Tighter tolerances are achievable with secondary sizing or machining, agreed per part during quoting.
What is the MOQ and lead time for Powder Metallurgy Bushings?
MOQ is 1000 pcs. Mold lead time is about 20 days (mold fee typically RMB 20–40k depending on part geometry), and production lead time is about 7 days once the mold is validated; secondary processing adds 3–5 days.
