Product Features
The 700 Series’ large oil reservoir provides efficient heat dissipation and lubrication for for a longer time operating life.
Its multi-position mounting flexibility permits installation in virtually any position.
Housings are straddle-milled, best and bottom, 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 maximum 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 output shaft assures capacity for excessive torque and overhung loads.
Pipe plugs allow convenient fill up, level, and drain in virtually 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 durable and built for 90° turns. Inline reducers (parallel shaft and planetary) happen to be an ideal meet for motors with high input speeds, or when gearmotor efficiency is important. Contact our technical sales staff for help identifying which gearbox choice 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 turn with optional dual output. The reducers come in 12 ratios which range from 5:1 to 100:1, with non-back-drivable ratios 30:1 and higher. Our right angle gearboxes were created 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 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 operation of our swiftness reducers. These gearboxes are made to deal with varying loads with little backlash. With framework sizes 52cm, 62cm, and 81cm, 12 ratios ranging from 5:1 to 308:1, we have a solution to suit your needs. Our 52 frame size is also available with plastic material gears for noise-delicate applications.
INLINE PLANETARY GEARBOX
inline-planetary-gearbox
Our inline planetary gearbox configurations provide the highest effectiveness and best result torque of most our quickness reducers. These gearboxes are designed to handle varying loads with small backlash. Planetary equipment reducers operate even 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 decision for constant duty applications. Their gear cluster design provides a highly effective technique for dissipating warmth. Parallel shaft gearboxes have the shortest length of our inline gear reducer options so they work well in environments with limited space. Our parallel shaft equipment reducers provide an affordable drop-in substitute solution for most small parallel shaft gearmotors.
Wormwheel gearboxes go by several names, including 90-degree gearboxes, right angle gearboxes, velocity reducers, worm equipment reducers and worm drive gearboxes. Gear decrease boxes include a gear arrangement when a gear in the kind of a screw, also called a worm, meshes with a worm gear. These gears are usually created from bronze and the worms will be steel or stainless steel.

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