RC60 1060
Steel
Linear Shafting
Note: Most competitive, most
commonly
inventoried shafting material |
Standard linear shafting is made from 1060 steel which
is case hardened to a surface hardness of Rockwell 60 hardness. This is
the best choice for applications which employ rolling element bearings:
linear ball bearings or roller type bearings i.e.,
Teflon Composite,
Linear Ball Bearings or our Jet Rail
Bearings. RC60 will
oxidize and rust. Thus, lubricated
bearings keep RC60
shafting protected. Keep this in mind when using a dry running bearing. |

Chrome
Plated 1060
Steel Linear Shafting |
Chrome Plated 1060 steel is an option when the system experiences
washdown/chemicals or is employed with
non-abrasive, self lubricating bearings like our Minuteman Self
Lubricating Bearing. Fluidline linear bearings. Chrome Plated
linear shafting is also used in applications that require a
decorative
finish. It is more expensive than standard
RC60 but only slightly - approx: 10-15% |

440C
Stainless
Linear Shafting |
This is a high carbon
martensitic ( increased
chromium
and carbon to improve toughness and corrosion
resistance ) stainless with moderate corrosion
resistance good strength
and the ability to obtain and
keep excellent hardness (Rc55)
and wear resistance. This grade supports rolling
element bearings which
require a hardened shaft. *Because this
stainless alloy
has carbon added to it, it will oxidize in
washdown
applications. It is allowed by many inspectors when rolling element
bearings are absolutely necessary. However, 300 series stainless steel
is preferable. |

300 Series Stainless
Linear Shafting
303, 304, 316
Note: 300 Stainless
alloys are almost
twice the weight of standard 1060 steel shafting.
This has design implications where weight is
a factor. |
Austenitic stainless steels, because of their high
chromium and nickel content, are the most corrosion
resistant of the
stainless group providing excellent
mechanical properties. They cannot
be hardened and are
not magnetic. All LM76 Minteman Self Lubricating
bearings ( Minuteman and FDA grades ) employ no
abrasive
fillers. Thus, they are totally compatible with
soft 300 series
stainless steels - the most corrosion resistant grades. 300 series
stainless grades: 303, 304
and 316 are the best choice in washdown/marine
and applications where
materials cannot be magnetic. 316
stainless is the
hardest
of
this family and the most corrosion resistant. It is
commonly employed in naval applications. |

Ceramic Coated
Aluminum Shafting
|
Ceramic Coated Aluminum linear shafting is manufactured
from T6061 extruded aluminum. The extrusion is ceramic coated
to make it
a lightweight, corrosion resistant shafting option. This shafting is not
an option for systems which experience high loads, impact or long spans
which may
see a high degree of defection. Although the ceramic
coating offers a RC60 plus hardness, it is not suitable for
use with linear ball bearings. If the shaft is totally coated( no bare aluminum ) it is FDA/USDA compliant and is
extremely tolerant of washdown and chemicals |

Nitronic
50
Linear Shafting
Note: Expensive |
Primary Elements:
Nitronic 50 Stainless Steel is composed
of between 20 and 23 percent Chromium, 11 to 13 percent Nickel,
4 to 6
percent Manganese, and 1.5 to 3 percent Molybdenum,
with the balance
being Iron. Also found in
Nitronic 50 are trace amounts of Carbon, Silicon, Sulfur, Phosphorus,
Nitrogen, Columbium and Vanadium.
Features: Nitronic 50 Stainless Steel is an austenitic
stainless steel with a blend of strength and corrosion resistance that
is better than Stainless Steel 316, 316L,
317 and 317L. In fact, Nitronic 50 has about double the yield strength
at room temperature compared to Stainless Steel 316/316L and
317/317L.
Additionally, Nitronic 50 Stainless Steel has good mechanical properties
at elevated and
sub-zero temperatures. Another characteristic of Nitronic
50 is that it does not
become magnetic even when severely cold worked -
unlike many other austenitic stainless steels.
Another advantage of
using Nitronic 50 Stainless Steel
is its outstanding corrosion
resistance in
harsh
environments, especially in marine applications.
As noted previously, Nitronic 50 is much stronger than
Stainless Steel
316/316L and 317/317L; however, the same fabrication equipment and
procedures used for the Stainless
Steel 300 grades can be utilized for Nitronic 50. In addition,
the same cooling techniques used for Stainless Steel
316/316L and 317/317L can be utilized for Nitronic 50. |

Added Lubricity.
The unique nature of the Armoloy�
TDC process will
enhance the lubricity of your Armoloy�
coated rails. This added
lubricity is especially important in
applications requiring
minimum to no lubricating agents
being present in the processing
line. Increased Corrosion
Resistance. Armoloy� will
improve the corrosion resistance
of
standard linear rails in most chemical or water
environments
to
be comparable to or exceed that of
440C stainless steel. Armoloy� coating also has the added
benefit of longer wear
life
than stainless steel
due to its
higher surface hardness (78Rc) and immediate cost
savings
realized from the use of non-stainless rails.
Armoloy� is
applied with a .0001/.0002"
deposit
per side, eliminating the
problem with major
size/tolerance clearances. Armoloy�
will create an absolute bond
to your linear rail that
will not
chip, flake, or peel in field applications. Armoloy� is
also
FDA-USDA approved for use without concern in food
and medical processing applications and is being used in
many applications where adverse conditions prevail. |
