The standard rod bushing cartridge material for
all Peninsular Models IMH steel and ILM aluminum metric air
cylinders is made from grade 65-45-12 high
strength ductile iron which provides for a durable wear surface
for most pneumatic cylinder applications.
However, some design
engineers from time to time request that the rod cartridge be made
from other materials which are less susceptible to a galling
condition that could occur between the piston rod and the I.D. of
the rod cartridge in various applications. One such material is
660 bearing bronze and another is our “Slip Tuff” coated rod
bearing cartridge which is superior in heavily side loaded
applications.
The cylinder rod bearing cartridges noted in the drawings below may be
manufactured out of different materials to meet the demands of
specific applications. All Peninsular model IMH and model ILM
metric
pneumatic cylinders contain a floating and self aligning rod
bearing cartridge that generally minimizes piston rod
misalignment by reducing side loading that is often found in most
automated manufacturing systems. In addition, all Peninsular
pneumatic cylinder piston rod bearing cartridges contain an
internal grease lubrication reservoir which dramatically increases the life of
the cartridge and its related seals.
Bronze Rod Bearing Cartridge
Some design
engineers from time to time request a bronze material that is less
susceptible to a galling condition that could occur between the
piston rod and the I.D. of the rod cartridge in various
applications. Peninsular uses a 660 bearing bronze material for
these applications when they become present. Note that bronze is a
softer material than ductile iron and when side load is present
one should be aware that bronze will wear much faster than the
ductile iron material.
To order or configure a cylinder with our 660 bearing bronze rod
cartridge material a /F must be specified at the end of the
Peninsular part numbering system. By selecting the “bronze rod
cartridge” in this configurator you will have selected a cylinder
with the rod bushing cartridge made from this bearing bronze
material and a /F will be present in the cylinder part number once
the cylinder is generated for configuration.
"SlipTuff" Coated Rod Bearing
Cartridge
Our “Slip Tuff” coated rod bushing cartridge
provides exceptional wear characteristics combined with a highly lubristic inside diameter of the rod cartridge. This special
coating has been successfully tested and proven throughout the
automobile industry on Peninsular hydraulic and pneumatic
cylinders in applications where severe side loaded conditions were
present. The use of our “Slip Tuff” coating feature will extend
the life of the rod bushing cartridge in
those applications where side loading has caused early cylinder
failure attributable to severe wear exerted upon the I.D. of the
cylinder rod cartridge.
Peninsular’s “Slip Tuff” coated rod bushing cartridge will still
contain the floating and self aligning feature as is present on
all Peninsular cylinders. In addition, the Peninsular “Slip Tuff”
rod cartridge when used with our pneumatic cylinders, will contain
our internal grease
reservoir which further increases the life of the cartridge
and its related seals.
By selecting the “Slip Tuff” coated rod cartridge” feature in this configurator,
you will have selected a cylinder with a special hard and
lubristic coating applied to our standard 65-45-12 high strength
ductile iron rod bushing cartridge.
When the “Slip Tuff” Coated Rod Cartridge feature is selected a /
Z
will appear near the end of the cylinder ordering number after the
cylinder is generated for configuration.
