Product Features
The 700 Series’ large oil reservoir provides efficient heat dissipation and lubrication for longer operating life.
Its multi-position mounting versatility allows for installation in virtually any position.
Housings are straddle-milled, top and bottom level, 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 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 result shaft assures convenience of 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
Correct 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 effectiveness is important. Contact our technical sales personnel for help identifying which gearbox option is most beneficial for you.
RIGHT ANGLE REDUCERS
WORM GEAR REDUCER
EP’s worm equipment reducers are designed with a hollow bore and allow for a corner change 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 are designed with five mounting choices providing versatility when incorporating the reducer into item.
RIGHT ANGLE BEVEL GEARBOX
bevel-right-angle-gearbox
The proper angle bevel gearbox combines the features of our right angle worm and planetary inline reducers. With a solid and efficient correct angle configuration, our correct angle planetary gearboxes provide a robust solution. The proper angle bevel gearbox will come 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 supply the smallest footprint and quietest operation of our speed reducers. These gearboxes are made to manage varying loads with small backlash. With framework sizes 52cm, 62cm, and 81cm, 12 ratios which range from 5:1 to 308:1, we have a solution to fit your needs. Our 52 frame size can be 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 output torque of most our quickness reducers. These gearboxes are made to manage varying loads with little backlash. Planetary gear reducers operate more quietly than parallel shaft reducers. With 18 ratio choices ranging from 5:1 to 1000:1, we have a solution to suit your needs.
PARALLEL SHAFT GEARBOX
parallel-shaft-gearbox
Parallel shaft gearboxes are the best choice for continuous duty applications. Their gear cluster design provides a highly effective method for dissipating temperature. Parallel shaft gearboxes possess the shortest length of our inline equipment reducer options therefore they work 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 go by several names, including 90-degree gearboxes, right position gearboxes, speed reducers, worm gear reducers and worm drive gearboxes. Gear reduction boxes include a gear arrangement in which a equipment in the form of a screw, also called a worm, meshes with a worm gear. These gears are typically made from bronze and the worms are steel 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 equipment reducers is definitely 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 direction of the result, a left-hand thread worm gearbox is required.
