Product Features
The 700 Series’ huge oil reservoir provides efficient heat dissipation and lubrication for longer operating life.
Its multi-position mounting flexibility permits installation in practically any position.
Housings are straddle-milled, best and bottom, for precise alignment of horizontal and vertical bases.
Internal baffles assure positive, leak-free venting.
The 700 Series’ rugged casing, fabricated of fine-grained, gear-quality cast iron, provides optimum strength for maximum durability, along with greater precision during worm and gear alignment.
EP Gear’s 700 Series high-strength bronze worm equipment 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 substantial torque and overhung loads.
Pipe plugs allow easy fill, level, and drain in practically any mounting position.
The 700 Series’ super-finished oil-seal diameters on both input and output shafts extend seal life.

GEARBOX REDUCERS
Right angle gearboxes (worm and planetary) are tough and built for 90° turns. Inline reducers (parallel shaft and planetary) are an ideal match for motors with substantial input speeds, or when gearmotor effectiveness is important. Contact our technical sales personnel for help determining which gearbox choice is most beneficial for you.
RIGHT ANGLE REDUCERS
WORM GEAR REDUCER
EP’s worm gear reducers are designed with a hollow bore and invite for a corner change with optional dual output. 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 flexibility when incorporating the reducer into item.
RIGHT ANGLE BEVEL GEARBOX
bevel-right-angle-gearbox
The proper angle bevel gearbox combines the top features of our right angle worm and planetary inline reducers. With a solid and efficient right angle configuration, our right angle planetary gearboxes offer a robust solution. The proper angle bevel gearbox comes in 18 ratios ranging 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 operation of our acceleration reducers. These gearboxes are designed to deal with varying loads with small 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 material gears for noise-delicate applications.
INLINE PLANETARY GEARBOX
inline-planetary-gearbox
Our inline planetary gearbox configurations provide the highest performance and best result torque of most our quickness reducers. These gearboxes are designed to handle varying loads with small backlash. Planetary equipment reducers operate even more quietly than parallel shaft reducers. With 18 ratio choices which range from 5:1 to 1000:1, we’ve a solution to fit your needs.
PARALLEL SHAFT GEARBOX
parallel-shaft-gearbox
Parallel shaft gearboxes are the top decision for continuous duty applications. Their gear cluster design provides an effective approach for dissipating high temperature. Parallel shaft gearboxes possess the shortest amount of our inline gear reducer options so they work well in conditions with limited space. Our parallel shaft equipment reducers offer an affordable drop-in replacement solution for most little parallel shaft gearmotors.
Wormwheel gearboxes pass several names, including 90-degree gearboxes, right position gearboxes, quickness reducers, worm equipment reducers and worm travel gearboxes. Gear reduction boxes feature a gear arrangement when a gear in the form of a screw, also referred to as a worm, meshes with a worm gear. These gears are usually made from bronze and the worms will be steel or stainless steel.

While worm gears act like a spur equipment, the worm gearboxes are considerably smaller than other gear reduction boxes. A major benefit of worm gear reducers is certainly that they produce an output that is 90° from the input and can be used to transmit larger torque or decrease rotational speed. Most often, a worm gearbox has right hands threads; to improve the path of the output, a left-hand thread worm gearbox is necessary.
