Product Features
The 700 Series’ large oil reservoir provides efficient heat dissipation and lubrication for longer operating lifestyle.
Its multi-position mounting flexibility 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 casing, fabricated of fine-grained, gear-quality cast iron, provides maximum strength for optimum durability, in addition to 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 improve thrust and overhung load capacities, sizes 713-760.
Our 700 Series’ high-strength steel output shaft assures convenience of high torque and overhung loads.
Pipe plugs allow easy fill, level, and drain in any mounting position.
The 700 Series’ super-finished oil-seal diameters on both input and output shafts extend seal life.
Both 2D and 3D CAD drawings are available in our eCatalog.
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 insight speeds, or when gearmotor effectiveness is important. Get in touch with our technical sales personnel for help identifying which gearbox alternative is best for you.
RIGHT ANGLE REDUCERS
WORM GEAR REDUCER
EP’s worm gear reducers were created with a hollow bore and invite for a corner convert with optional dual output. 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 are designed 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 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 which range 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 provide the smallest footprint and quietest operation of our rate reducers. These gearboxes are designed to deal with varying loads with little backlash. With body 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 material gears for noise-sensitive applications.
INLINE PLANETARY GEARBOX
inline-planetary-gearbox
Our inline planetary gearbox configurations supply the highest performance and best output torque of all our velocity reducers. These gearboxes are created to manage varying loads with small backlash. Planetary gear reducers operate more quietly than parallel shaft reducers. With 18 ratio options ranging from 5:1 to 1000:1, we have a solution to fit your needs.
PARALLEL SHAFT GEARBOX
parallel-shaft-gearbox
Parallel shaft gearboxes are the best choice for continuous duty applications. Their gear cluster design provides an effective method for dissipating temperature. Parallel shaft gearboxes possess the shortest length of our inline gear reducer options therefore they work well in conditions with limited space. Our parallel shaft gear reducers provide an affordable drop-in alternative solution for most little parallel shaft gearmotors.
Wormwheel gearboxes pass several names, including 90-degree gearboxes, right angle gearboxes, velocity reducers, worm gear reducers and worm drive gearboxes. Gear decrease boxes feature a gear arrangement in which a equipment in the form of a screw, also known as a worm, meshes with a worm equipment. These gears are usually created from bronze and the worms are metal or stainless steel.

While worm gears act like a spur equipment, the worm gearboxes are significantly smaller than other gear reduction boxes. A main benefit of worm gear reducers is usually that they produce an output that’s 90° from the insight and can be utilized to transmit higher torque or decrease rotational speed. Most often, a worm gearbox offers right hand threads; to change the path of the result, a left-hands thread worm gearbox is necessary.
