Product Features
The 700 Series’ large oil reservoir provides efficient heat dissipation and lubrication for longer operating existence.
Its multi-position mounting versatility permits 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 optimum strength for optimum durability, as well as 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, level, and drain in virtually 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 input speeds, or when gearmotor efficiency is important. Contact our technical sales staff for help determining which gearbox option is best for you.
RIGHT ANGLE REDUCERS
WORM GEAR REDUCER
EP’s worm gear reducers are designed with a hollow bore and allow for a corner change with optional dual output. The reducers can be found in 12 ratios ranging from 5:1 to 100:1, with non-back-drivable ratios 30:1 and higher. Our correct angle gearboxes were created with five mounting options providing flexibility when incorporating the reducer into item.
RIGHT ANGLE BEVEL GEARBOX
bevel-right-angle-gearbox
The right angle bevel gearbox combines the 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 will come in 18 ratios which range from 5:1 to 1000:1, and it is back-drivable at all ratios.
INLINE REDUCERS
I-SERIES PLANETARY GEARBOX
i-series-planetary-gearbox
Our I-Series little planetary gearbox configurations supply the smallest footprint and quietest procedure of our quickness reducers. These gearboxes are designed to manage varying loads with little backlash. With frame sizes 52cm, 62cm, and 81cm, 12 ratios ranging from 5:1 to 308:1, we’ve a solution to fit your needs. Our 52 frame size can be available with plastic-type gears for noise-delicate applications.
INLINE PLANETARY GEARBOX
inline-planetary-gearbox
Our inline planetary gearbox configurations supply the highest performance and best output torque of all our rate reducers. These gearboxes are created to deal with varying loads with little backlash. Planetary gear reducers operate more quietly than parallel shaft reducers. With 18 ratio options which range from 5:1 to 1000:1, we’ve a solution to suit 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 temperature. Parallel shaft gearboxes possess the shortest amount of our inline equipment reducer options so they work well in environments with limited space. Our parallel shaft equipment reducers provide an affordable drop-in replacement solution for most small parallel shaft gearmotors.
Wormwheel gearboxes pass several names, including 90-degree gearboxes, right position gearboxes, rate reducers, worm equipment reducers and worm drive gearboxes. Gear reduction boxes feature a gear arrangement when a equipment in the type of a screw, also referred to as a worm, meshes with a worm equipment. These gears are usually created from bronze and the worms are metal or stainless steel.

While worm gears act like a spur equipment, the worm gearboxes are significantly smaller than other gear reduction boxes. A major benefit of worm gear reducers is usually that they create an output that is 90° from the insight and can be used to transmit higher torque or reduce rotational speed. Frequently, a worm gearbox offers right hand threads; to improve the direction of the result, a left-hands thread worm gearbox is required.
