Professional manufacturer of honed tube, founded in 2004, major in honed tube, hydraulic tube, chrome rod, chrome bar, chrome shaft, at present we are biggest manufacturer and wholesaler in north of China.


Description

Our hydraulic honed tube is produced using our “Suitable To Hone” Drawn Over Mandrel (DOM) and Cold Drawn Seamless (CDS).

The honing process involves using abrasive polishing stones and abrasive paper to remove small amounts of material, to produce extremely precise ID dimensions and improved finishes.

honed tube is ready to use for hydraulic cylinder applications without further ID processing.
