S/N Bush Copper – Industrial Sewing Machine Copper Sleeve Bearing

The S/N Bush Copper is a precision-machined copper alloy sleeve bearing for industrial sewing machines. Stamped with the MB-Organ diamond logo, this self-lubricating copper bush provides excellent shaft support and reduces friction in high-speed rotating assemblies. Copper bushings are preferred in industrial sewing machines for their natural lubrication properties, thermal conductivity, and resistance to seizing. This bush is designed as a direct replacement for worn or damaged copper bushings in S/N (single needle) series and compatible industrial machines. Quality Control Approved by MB-Organ, it is machined to tight tolerances for minimal shaft clearance and long service life. A key part for smooth machine operation.
