Product Features
The 700 Series’ huge oil reservoir provides efficient heat dissipation and lubrication for longer operating lifestyle.
Its multi-position mounting versatility allows for 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 optimum durability, and also 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 increase 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 existence.

GEARBOX REDUCERS
Right angle gearboxes (worm and planetary) are tough and built for 90° turns. Inline reducers (parallel shaft and planetary) are a perfect match for motors with high input speeds, or when gearmotor effectiveness is important. Get in touch with our technical sales staff for help identifying which gearbox solution is most beneficial for you.
RIGHT ANGLE REDUCERS
WORM GEAR REDUCER
EP’s worm equipment reducers are designed with a hollow bore and invite for a corner turn with optional dual output. 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 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 good and efficient right angle configuration, our correct 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, 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 supply the smallest footprint and quietest procedure of our swiftness reducers. These gearboxes are designed to manage varying loads with little backlash. With framework 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 material gears for noise-sensitive applications.
INLINE PLANETARY GEARBOX
inline-planetary-gearbox
Our inline planetary gearbox configurations provide the highest effectiveness and best output torque of most our rate reducers. These gearboxes are created to handle varying loads with small backlash. Planetary equipment reducers operate more quietly than parallel shaft reducers. With 18 ratio options ranging from 5:1 to 1000:1, we’ve a solution to fit your needs.
PARALLEL SHAFT GEARBOX
parallel-shaft-gearbox
Parallel shaft gearboxes are the best choice for constant duty applications. Their gear cluster design provides a highly effective method for dissipating heat. Parallel shaft gearboxes have the shortest amount of our inline equipment reducer options therefore they work well in conditions with limited space. Our parallel shaft gear reducers offer an affordable drop-in replacement solution for most little parallel shaft gearmotors.
Wormwheel gearboxes go by several names, including 90-degree gearboxes, right position gearboxes, rate reducers, worm equipment reducers and worm drive gearboxes. Gear reduction boxes include a gear arrangement when a equipment in the kind of a screw, also referred to 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 significantly smaller than other gear reduction boxes. A principal benefit of worm equipment reducers is definitely that they generate an output that is 90° from the input and can be used to transmit higher torque or decrease rotational speed. Frequently, a worm gearbox offers right hand threads; to change the path of the output, a left-hand thread worm gearbox is necessary.
