Product Features
The 700 Series’ large oil reservoir provides efficient heat dissipation and lubrication for longer operating lifestyle.
Its multi-position mounting flexibility allows for installation in practically any position.
Housings are straddle-milled, top and bottom, for precise alignment of horizontal and vertical bases.
Internal baffles assure positive, leak-free venting.
The 700 Series’ rugged housing, fabricated of fine-grained, gear-quality cast iron, provides maximum strength for optimum durability, in addition to greater precision during worm and gear alignment.
EP Gear’s 700 Series high-strength bronze worm gear is straddle mounted between heavy-duty tapered roller bearings to improve thrust and overhung load capacities, sizes 713-760.
Our 700 Series’ high-strength steel result shaft assures capacity for high torque and overhung loads.
Pipe plugs allow easy fill up, level, and drain in any mounting position.
The 700 Series’ super-finished oil-seal diameters on both input and output shafts extend seal lifestyle.

GEARBOX REDUCERS
Right angle gearboxes (worm and planetary) are rugged and built for 90° turns. Inline reducers (parallel shaft and planetary) are an ideal match for motors with high insight speeds, or when gearmotor efficiency is important. Contact our technical sales personnel for help determining which gearbox remedy is most beneficial for you.
RIGHT ANGLE REDUCERS
WORM GEAR REDUCER
EP’s worm worm reduction gearbox equipment reducers were created with a hollow bore and allow for a corner turn with optional dual result. The reducers can be found in 12 ratios which range from 5:1 to 100:1, with non-back-drivable ratios 30:1 and higher. Our right angle gearboxes were created with five mounting options providing versatility when incorporating the reducer into product.
RIGHT ANGLE BEVEL GEARBOX
bevel-right-angle-gearbox
The right angle bevel gearbox combines the top features of our right angle worm and planetary inline reducers. With a good and efficient right angle configuration, our right angle planetary gearboxes offer a robust solution. The right angle bevel gearbox comes in 18 ratios ranging from 5:1 to 1000:1, in fact it is back-drivable at all ratios.
INLINE REDUCERS
I-SERIES PLANETARY GEARBOX
i-series-planetary-gearbox
Our I-Series small planetary gearbox configurations supply the smallest footprint and quietest operation of our quickness reducers. These gearboxes are designed to handle varying loads with little backlash. With frame sizes 52cm, 62cm, and 81cm, 12 ratios which range from 5:1 to 308:1, we have a solution to suit your needs. Our 52 frame size can be available with plastic material gears for noise-sensitive applications.
INLINE PLANETARY GEARBOX
inline-planetary-gearbox
Our inline planetary gearbox configurations supply the highest effectiveness and best output torque of most our swiftness reducers. These gearboxes are made to manage varying loads with little backlash. Planetary equipment reducers operate more quietly than parallel shaft reducers. With 18 ratio options which range from 5:1 to 1000:1, we have a solution to fit your needs.
PARALLEL SHAFT GEARBOX
parallel-shaft-gearbox
Parallel shaft gearboxes will be the top choice for continuous duty applications. Their gear cluster design provides a highly effective method for dissipating warmth. Parallel shaft gearboxes have the shortest length of our inline equipment reducer options therefore they work very well in environments with limited space. Our parallel shaft equipment reducers offer an affordable drop-in substitute solution for most small parallel shaft gearmotors.
Wormwheel gearboxes go by several names, including 90-degree gearboxes, right angle gearboxes, quickness reducers, worm equipment reducers and worm drive gearboxes. Gear reduction boxes feature a gear arrangement in which a equipment in the form of a screw, also called a worm, meshes with a worm equipment. These gears are typically made from bronze and the worms are metal or stainless steel.

While worm gears are similar to a spur equipment, the worm gearboxes are considerably smaller than other equipment reduction boxes. A major benefit of worm gear reducers is usually that they create an output that is 90° from the input and can be used to transmit higher torque or decrease rotational speed. Frequently, a worm gearbox provides right hand threads; to improve the path of the output, a left-hand thread worm gearbox is necessary.
