- Features
- Continuous self-lubrication, low friction and noise, sleeve/flange/thrust/custom forms, high dimensional stability
- Application
- Household appliances (washing machines, fans, kitchen equipment), electric motors, pumps and compressors, automotive window regulators and wiper motors, industrial machinery, robotics and automation.
Frequently Asked Questions
What materials and process are used for Powder Metallurgy Self-Lubricating Bearings?
Powder Metallurgy Self-Lubricating Bearings is made from Oil-impregnated sintered PM alloys 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 Self-Lubricating Bearings 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 Self-Lubricating Bearings?
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.
