Our regular 700 Series – the heart of EP Gear’s swiftness reducer products – has recently been serving industry reliably for over 40 years. Its proven modular design has set the market standard for functionality and may be the most imitated product in today’s worm gear rate reducer marketplace. But why accept a knock-off when you’re able to have the initial – from EP Gear.

Product Features
The 700 Series’ huge oil reservoir provides efficient heat dissipation and lubrication for much longer operating life.
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 great, leak-free venting.
The 700 Series’ rugged housing, fabricated of fine-grained, gear-quality cast iron, provides optimum strength for optimum durability, along with 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 capacity for high torque and overhung loads.
Pipe plugs allow convenient fill, 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
Correct angle gearboxes (worm and planetary) are tough and built for 90° turns. Inline reducers (parallel shaft and planetary) will be an ideal meet for motors with substantial input speeds, or when gearmotor performance is important. Contact our technical sales staff for help identifying which gearbox answer is most beneficial for you.
RIGHT ANGLE REDUCERS
WORM GEAR REDUCER
EP’s worm gear reducers were created with a hollow bore and invite for a corner switch with optional dual result. The reducers come in 12 ratios which range 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 flexibility when incorporating the reducer into product.
RIGHT ANGLE BEVEL GEARBOX
bevel-right-angle-gearbox
The right angle bevel gearbox combines the features of our correct angle worm and planetary inline reducers. With a good and efficient right angle configuration, our right angle planetary gearboxes offer a robust solution. The proper 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 acceleration reducers. These gearboxes are made to deal with varying loads with small backlash. With body sizes 52cm, 62cm, and 81cm, 12 ratios which range from 5:1 to 308:1, we’ve a solution to suit your needs. Our 52 frame size can be available with plastic-type gears for noise-delicate applications.
INLINE PLANETARY GEARBOX
inline-planetary-gearbox
Our inline planetary gearbox configurations supply the highest effectiveness and best result torque of most our quickness reducers. These gearboxes are created to handle varying loads with small backlash. Planetary gear reducers operate more quietly than parallel shaft reducers. With 18 ratio choices 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 will be the top choice for continuous duty applications. Their equipment cluster design provides a highly effective approach for dissipating warmth. Parallel shaft gearboxes possess the shortest length of our inline equipment reducer options therefore they work very well in conditions with limited space. Our parallel shaft equipment reducers offer an affordable drop-in replacement solution for most little parallel shaft gearmotors.
Wormwheel gearboxes pass several names, including 90-degree gearboxes, right position gearboxes, speed reducers, worm gear reducers and worm travel gearboxes. Gear decrease boxes feature a gear arrangement when a gear in the kind of a screw, also referred to as a worm, meshes with a worm gear. These gears are typically made from bronze and the worms will be metal or stainless steel.

While worm gears act like a spur gear, the worm gearboxes are considerably smaller than other equipment reduction boxes. A main benefit of worm equipment reducers can be that they create an output that is 90° from the input and can be used to transmit higher torque or reduce rotational speed. Frequently, a worm gearbox provides right side threads; to improve the path of the result, a left-hand thread worm gearbox is required.
