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 virtually 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 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 increase 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 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.
Both 2D and 3D CAD drawings are available in our eCatalog.
GEARBOX REDUCERS
Right angle gearboxes (worm and planetary) are rugged and built for 90° turns. Inline reducers (parallel shaft and planetary) are a perfect match for motors with high input speeds, or when gearmotor performance 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 gear reducers are designed with a hollow bore and invite for a corner switch with optional dual result. The reducers come 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 versatility when incorporating the reducer into item.
RIGHT ANGLE BEVEL GEARBOX
bevel-right-angle-gearbox
The right 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 right angle bevel gearbox comes in 18 ratios ranging 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 small planetary gearbox configurations provide the smallest footprint and quietest procedure of our rate reducers. These gearboxes are made to handle varying loads with small backlash. With frame sizes 52cm, 62cm, and 81cm, 12 ratios which range from 5:1 to 308:1, we’ve 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 provide the highest effectiveness and best result torque of all our rate reducers. These gearboxes are designed to handle varying loads with small backlash. Planetary equipment reducers operate more quietly than parallel shaft reducers. With 18 ratio options which range 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 top choice for constant duty applications. Their gear cluster design provides an effective method for dissipating warmth. Parallel shaft gearboxes possess the shortest amount of our inline gear reducer options therefore they work very well in environments with limited space. Our parallel shaft equipment reducers provide an affordable drop-in alternative solution for most little 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 reduction boxes include a gear arrangement in which a equipment in the kind of a screw, also known as a worm, meshes with a worm gear. These gears are typically created 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 gear reduction boxes. A main benefit of worm gear reducers is that they create an output that is 90° from the insight and can be utilized to transmit higher torque or decrease rotational speed. Frequently, a worm gearbox has right hand threads; to improve the direction of the result, a left-hands thread worm gearbox is necessary.
