Product Details

MH crank connection rod is a precision-machined steel replacement part for the drive assembly of 307 household sewing machines.

The rod transfers motion within the machine's drive mechanism, so it is turned from steel to a close, repeatable tolerance that keeps the linkage running true and quiet under continuous operation.

The machined finish resists wear at the bearing surfaces, extending service life where the part flexes through every stitch cycle.

Key Selling Points

• Precision-machined steel: MH turns the crank connection rod from steel to a close tolerance, giving the drive linkage an accurate, repeatable fit.

• Direct 307 replacement: The rod matches the original drive-assembly component of the 307 household sewing machine, so repairs go back to factory motion.

• Wear-resistant service life: Machined bearing surfaces resist wear through continuous stitch cycles, keeping the drive mechanism running smoothly over time.

• Custom machining: MH can reproduce the connection rod from a buyer's reference sample, supporting repair shops that service other sewing-machine models.
