e Series
High Efficiency Gear Reducers
Patent Pending
A Regal Brand
The Grove Gear IronMan E Series is a high efficiency, right angle gear reducer designed for
increased torque density, reduced inventory and improved efficiency. By utilizing modified helical-bevel technology, the E Series is able to operate at 90% efficiency and can provide
up to 60% higher torque than a typical worm gear reducer. Through various accessories
and modular components, the E Series recreates the critical dimensions of a standard worm
gearbox and provides the opportunity to reduce inventory.
More Power
60% more torque than a typical worm gear reducer
Opportunity to downsize motor and gear reducer
Less Inventory
Four models replace 10 typical worm gear reducer center distances
Plug-in shafts and mounting accessories create hundreds of style combinations
Higher Efficiency
90% operating efficiency
Rapid payback through energy cost savings

More Power
The Grove Gear IronMan E Series offers more
torque density than a typical worm reducer in the
same mounting footprint. It allows for motor and
gear reducer downsizing opportunities.
Less Inventory
With this modular design, 10 typical worm
gear center distances can be replaced with
just four E Series units. Plug-in shafts and
mounting accessories create hundreds of style
combinations. By utilizing these modular
features, the E Series can be used as a drop
in replacement to worm gear reducers.

Higher Efficiency
The Grove Gear IronMan E Series Gear Reducer yields 90% operating efficiency and meets the
increasing demand for high efficiency products in industrial applications. This revolutionary product
utilizes modified helical-bevel technology to provide superior efficiency with the same dimensional
footprint as worm gear reducers. The compact design is an ideal alternative to traditional high
efficiency units. Placing greater attention on the efficiency of the entire power transmission
system can reduce energy costs while boosting productivity, reliability and profitability.

Premium Features
Precision mounting surfaces and extra
threaded bolt holes on top and bottom for
flexibility and to accept a wide range of stock
mounting accessories.
Oversized positively-retained high speed
input shaft bearing for higher shock load
capacity, shaft alignment and seal life. Ideal for
frequent starting and reversing applications.
Push-off holes drilled
and tapped into flange
for quick motor removal
on quill input styles
(56 & 140TC frames).
Premium Grade
5 zinc-plated heattreated bolts
used throughout.
Factory filled with premium
Mobil Glygoyle 460 polyalkalene
glycol (PAG) lubricant.
Cast iron IEC and NEMA
C input flange with machined
fits for precision alignment of
motor and bearings.
Multiple venting options for
multi-position mounting.
Tapered roller bearings on output shaft for
high overhung and thrust load capacities.
Robust output shaft of
high strength steel alloy
for superior torque and
overhung load capacities.
Quick Selection
Based on required output RPM and input motor horsepower, read across chart
to see where an e Series reducer would be appropriate. As a rule of thumb, use
1.00 service factor chart for applications having uniform loads with up to 10 hours
service duration per day. This chart is to be considered as a guide only. Contact
Factory with specific application information.
