Product Description

20 mm Custom Bronze Bushing – Oil-Embedded Sintered Type

SINTERED BRONZE BUSHING 20X28X40 Additional image 1

DALON’s custom bronze bushing (20×28×40 mm) is a precision-engineered, sintered sleeve bearing designed to meet specific fit and function requirements for industrial motion systems. Manufactured using powder metallurgy, this bushing offers self-lubrication, dimensional consistency, and long-term reliability, making it ideal for custom assemblies where standard bearings may not fit.

This sleeve-type bushing features a porous bronze matrix impregnated with lubricating oil, reducing friction and wear in both rotating and oscillating motion.
