Product Description

Description:

Our honed tube is produced using our Suitable To Hone Drawn Over Mandrel (DOM) and Cold Drawn Seamless CDS. This honed tube is ready to use for hydraulic cylinder applications without further ID processing.
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.

Applications:

Hydraulic Cylinder, Hydraulic Jack, hydraulic oil cylinder pneumatic cylinder, petrifaction oil pump, coal mine, engineering machinery, crane and transport machinery, auto transmission axes, plastic machinery, engineering machinery, crane and transport machinery, auto transmission axes, plastic machinery, hydraulic oil cylinder, pneumatic cylinder, absorber, spin printing and dyeing.
