Product Features
The 700 Series’ huge oil reservoir provides efficient heat dissipation and lubrication for longer operating lifestyle.
Its multi-position mounting versatility allows for installation in virtually any position.
Housings are straddle-milled, best and bottom level, 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, as well as 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 output 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 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 high input speeds, or when gearmotor effectiveness is important. Contact our technical sales personnel for help determining which gearbox alternative is best for you.
RIGHT ANGLE REDUCERS
WORM GEAR REDUCER
EP’s worm equipment reducers were created with a hollow bore and invite for a corner change 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 correct 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 right angle bevel gearbox combines the top features of our correct angle worm and planetary inline reducers. With a solid and efficient correct angle configuration, our right angle planetary gearboxes offer a robust solution. The right angle bevel gearbox comes in 18 ratios which range 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 little planetary gearbox configurations provide the smallest footprint and quietest procedure of our swiftness 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 have a solution to fit your needs. Our 52 frame size can be available with plastic gears for noise-sensitive applications.
INLINE PLANETARY GEARBOX
inline-planetary-gearbox
Our inline planetary gearbox configurations provide the highest effectiveness and best output torque of most our velocity reducers. These gearboxes are made 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 best choice for constant duty applications. Their gear cluster design provides a highly effective method for dissipating heat. Parallel shaft gearboxes have the shortest length of our inline equipment reducer options therefore they work very well in conditions with limited space. Our parallel shaft gear 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, speed reducers, worm equipment reducers and worm drive gearboxes. Gear decrease boxes feature a gear arrangement in which a equipment in the kind of a screw, also called a worm, meshes with a worm gear. These gears are usually made from bronze and the worms are steel or stainless steel.

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