SAE1045 burnished cylinder tubing is a kind of precision seamless steel tubes with smooth bore and tight ID tolerance used to produce hydraulic cylinder barrels. In Changzhou Chengxin, we manufacture seamless hydraulic cylinder tubes including hydraulic cold drawn (+cold rolled) seamless tubes suitable for honing, honed tubes,and skived&roller burnished tubes upto 325mm*300mm. The best ID tolerance we can achieve is H7 through skiving&roller burnishing. The surface roughness(Ra) can be 0.25um max.
