SUPERIOR SEALING CAPABILITIES:
The steel industry, especially the rolling operations of a mill, is perhaps the
most demanding environment of any industry. To survive, a gearbox must protect itself
from heat, moisture, chemicals and air-borne contaminates.
If seal integrity is lost, the gearbox lubrication will be compromised. Once the
lubrication is lost or contaminated, bearing failure will result.
The following are the design criteria for the gearbox seal:
Superior barrier to keep contaminates out of the
Exceptional oil containment.
Optional seal composition that will increase the
chemical resistance and operating temperature of the
It must be of compact, power-dense design, so that even high ratio units are
not bulky or heavy. Individual roll drive designs, in particular, are subject to restrictive
To accommodate variations in design, motor requirements, input speeds and
ratios, the selected reducer must be very versatile.
The following criteria must be adaptable, allowing designers to develop a
configuration based upon system requirements:
• Integral Motor
• C-Face Adapter with coupling
• C-Face Flange with hollow keyed I/P
• Top Mount
• Shovel Base Mount
• Foot Mount
• Wall Mount
• Flange Mount
HIGH SHOCK LOAD CAPABILITIES:
Non-uniform and heavy shock loads are considered normal operating
conditions. Many design engineers handle this requirement by increasing the service
factor of the gearbox.
According to the American Gear Manufactures Association (AGMA) selection
criteria, reducers can be selected by Service Factor or Load Classification. Both are a
means of classifying different equipment and applications into a uniform guideline
useful for reducer selection. For Metal Processing, AGMA makes the following
The following are the design criteria for
high shock load requirements:
Service Factor no less than 1.25
Ductile Iron housing to withstand high
Internal Component Design to include:
• Bearing Grade Steel, Heat Treated
• Strict Tolerances
• Precision Finish
Two-high : Two opposing rolls
Three-high : Work passes through rolls in both directions
Four-high : Backing rolls support smaller work rolls
Cluster mill : Multiple backing rolls on smaller rolls
Tandem rolling mill : Sequence of two-high mills

Rolling mills have several stages, where the each stage successively reduces the thickness of
the stock until the desired cross section is achieved.
Multiple backing rolls allow even smaller roll diameters
