FAQ

Frequently Asked Questions

What materials and process are used for Oil-impregnated Bronze Bearing?

Oil-impregnated Bronze Bearing is made from Wear-resistant oil-impregnated bronze alloy 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 are the key specifications of Oil-impregnated Bronze Bearing?

Typical specifications: Series: 3-series, 5-series, 7-series, N-series micro-motor bearings; Smallest Mass-produced Size: Ø0.5 × Ø1.0 × 0.5 mm; Process: Precision PM sintering; MIM for complex shapes; sizing calibration + oil impregnation. The full parameter list is in the specifications table on this page; custom requirements can be discussed against your drawing.

What is the MOQ and lead time for Oil-impregnated Bronze Bearing?

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.
