Hydraulic Cylinder 2Mm Diameter Chrome Plated Steel Bar 800 - 1200
HV 10 Micron Chrome Thickness
Hard chrome plated bars are known as Chrome plated rods or chrome
plated shafts also, they are usually used to manufacturing or
repairing the hydraulic piston shafts. This product is widely used
for most piston shaft applications in hydraulic and pneumatic
cylinders.
Our chrome plated steel bars are manufactured from round steel bar
through high precision polishing, and chrome plated with a certain
thickness, the thickness of chrome plated layer is usually min. 20
microns.
Materials:
As the leading chrome plated bar supplier, our factory can produce
chrome plated shafts in wide range of materials as carbon steel and
stainless steels. The most popular steel grades of carbon steel
chrome plated shafts are JIS S45C, SAE1045, AISI 1045 / 1050, DIN
CK45.
Size range:
We can manufacture chrome plated steel bars with size range from
external diameter 6 mm to 800 mm.
We supply both metric size chrome plated shafts and imperial sizes
chrome plated bar.
Packing:
Our chrome plated steel bars usually is packed with plastic sleeves
or paper tubes. Also we can provide packing method of wooden cases
on customers’ requests.
Chrome plated thickness:
The thickness of the chrome plated layer can be 10 microns to 30
microns. And the most popular requirements is that the chrome layer
of the chrome plated shaft is min. 20 microns.
Applications:
Chrome plated steel bars are usually used together with honed tubes
for manufacturing or repairing the hydraulic cylinders or pneumatic
cylinders. Beside this, the chrome plated rods also are widely used
as shafts of various machines, where high precision and high smooth
surface is required.
As the high quality China honed tube & chrome plated bar
manufacturer, our factory also produces honed tubes and chrome
plated hollow bars,
our products are exported to customers in many countries abroad,
and gained very good reputation in the field.
