Our standard 700 Series – the heart of EP Gear’s swiftness reducer product line – has been serving industry reliably for over 40 years. Its proven modular style has set the market standard for efficiency and may be the most imitated item in the current worm gear rate reducer market. But why settle for a knock-off when you can have the original – from EP Gear.

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, best 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 optimum strength for optimum durability, as well as 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 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 life.

GEARBOX REDUCERS
Right angle gearboxes (worm and planetary) are durable and built for 90° turns. Inline reducers (parallel shaft and planetary) are an ideal match for motors with high input speeds, or when gearmotor performance is important. Contact our technical sales personnel for help identifying which gearbox alternative is most beneficial for you.
RIGHT ANGLE REDUCERS
WORM GEAR REDUCER
EP’s worm gear reducers were created with a hollow bore and allow for a corner turn 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 are designed with five mounting choices providing flexibility when incorporating the reducer into item.
RIGHT ANGLE BEVEL GEARBOX
bevel-right-angle-gearbox
The right angle bevel gearbox combines the features of our right angle worm and planetary inline reducers. With a good and efficient right angle configuration, our right angle planetary gearboxes offer a robust solution. The right angle bevel gearbox will come 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 operation of our acceleration reducers. These gearboxes are created to handle varying loads with small backlash. With framework 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 material gears for noise-delicate applications.
INLINE PLANETARY GEARBOX
inline-planetary-gearbox
Our inline planetary gearbox configurations provide the highest efficiency and best result torque of most our velocity reducers. These gearboxes are created to deal with 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 top choice for continuous duty applications. Their equipment cluster design provides an effective method for dissipating high temperature. Parallel shaft gearboxes have the shortest amount of our inline gear reducer options therefore they work very well in conditions with limited space. Our parallel shaft gear reducers offer an affordable drop-in replacement solution for most small parallel shaft gearmotors.
Wormwheel gearboxes go by 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 gear in the type of a screw, also referred to as a worm, meshes with a worm equipment. These gears are typically made from bronze and the worms are steel or stainless steel.

While worm gears are similar to a spur equipment, the worm gearboxes are considerably smaller than other gear reduction boxes. A primary benefit of worm equipment reducers is that they generate an output that is 90° from the insight and can be utilized to transmit higher torque or reduce rotational speed. Most often, a worm gearbox provides right hand threads; to improve the direction of the result, a left-hand thread worm gearbox is necessary.
