Product Features
The 700 Series’ huge oil reservoir provides efficient heat dissipation and lubrication for longer operating life.
Its multi-position mounting flexibility allows for installation in practically any position.
Housings are straddle-milled, top and bottom level, for precise alignment of horizontal and vertical bases.
Internal baffles assure great, leak-free venting.
The 700 Series’ rugged casing, fabricated of fine-grained, gear-quality cast iron, provides maximum strength for optimum durability, and also 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 increase thrust and overhung load capacities, sizes 713-760.
Our 700 Series’ high-strength steel output 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 existence.

GEARBOX REDUCERS
Correct angle gearboxes (worm and planetary) are durable and built for 90° turns. Inline reducers (parallel shaft and planetary) happen to be an ideal match for motors with great input speeds, or when gearmotor effectiveness is important. Contact our technical sales staff for help identifying which gearbox remedy is best for you.
RIGHT ANGLE REDUCERS
WORM GEAR REDUCER
EP’s worm equipment reducers are designed with a hollow bore and invite for a corner switch with optional dual result. 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 right angle gearboxes were created with five mounting choices providing versatility when incorporating the reducer into product.
RIGHT ANGLE BEVEL GEARBOX
bevel-right-angle-gearbox
The proper angle bevel gearbox combines the features of our correct angle worm and planetary inline reducers. With a solid and efficient correct angle configuration, our correct 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 small planetary gearbox configurations provide the smallest footprint and quietest operation of our speed reducers. These gearboxes are designed to deal with varying loads with little backlash. With body sizes 52cm, 62cm, and 81cm, 12 ratios ranging from 5:1 to 308:1, we have a solution to fit your needs. Our 52 frame size is also available with plastic-type gears for noise-sensitive applications.
INLINE PLANETARY GEARBOX
inline-planetary-gearbox
Our inline planetary gearbox configurations supply the highest effectiveness and best result torque of all our swiftness reducers. These gearboxes are made to handle varying loads with small backlash. Planetary equipment reducers operate more quietly than parallel shaft reducers. With 18 ratio options ranging from 5:1 to 1000:1, we’ve 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 an effective method for dissipating heat. Parallel shaft gearboxes possess the shortest length of our inline gear reducer options so they work very well in conditions with limited space. Our parallel shaft gear reducers provide an affordable drop-in substitute solution for most small parallel shaft gearmotors.
Wormwheel gearboxes pass several names, including 90-degree gearboxes, right angle gearboxes, velocity reducers, worm equipment reducers and worm travel gearboxes. Gear decrease boxes feature a gear arrangement in which a gear in the kind of a screw, also known as a worm, meshes with a worm gear. These gears are usually made from bronze and the worms are metal or stainless steel.

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