Inline Planetary Gear Reducer Options
Gearboxes are known by many different titles, including equipment drives, reducers, gear reducers, velocity reducers, and gearmotors. All terms can be used pretty much interchangeably when refering to inline planetary gear reducers.
Spur In-Line Gearboxes
Ever-Power offers a complete line of compact, light-weight spur gear inline planetary equipment reducers. These inline gearboxes can be immediate mounted to motors or used in combination with shaft coupling. Ratios from 2:1 to 625:1 are available, with torque values ranging from 0.13Nm to 90Nm.
Input speed: up to 4,000 RPM
Precision machined aluminum housing
Dual ball bearings on all shafts
Encoder Low Backlash In-Line Gearboxes
These compact, lightweight, low backlash gear drives were created specifically for encoder applications. They employ a low second of inertia at the shaft insight, and so are rated for input speeds up to 3,000 RPM. Gear ratios from 4.96:1 to 3600:1 can be found, in two frame sizes. Synchro cleats for our encoder gearboxes can be found from stock.
Result torque: 1 oz.-inch
Backlash: 15 arc-minutes (at any ratio)
Ratios from 4.96:1 to 3600:1
Input speeds up to 3,000 RPM
Diameter: 1-1/16” or 1-3/4”
Black anodized aluminum housing
303 stainless gears and shafts
Ball bearings
Low Backlash Inline Taper Gearboxes
Our taper gearmotors are inline planetary equipment reducer boxes with backlash equal to or much better than 8 arc/minute. These inline gearboxes are made for applications where space is bound, and are offered either as a shaft input or installed to a 24V DC motor.
Low backlash: ≤8 arc/min. at input
Compact design
Shaft insight or with mounted motor
Ratios from 2:1 to 16:1
Output torque ideals from 1.14Nm to 12.7Nm
Epicyclic (Planetary) Servo Gearboxes
The Ever-Power type of internal epicyclic servo reducers are extremely rugged and compact. These planetary gearboxes have fully-machined housings (aluminum or steel), and so are outfitted with ball bearings throughout. Our inline planetary gear reducers offer flexible motor mounting options and may deliver result torques up to 380 Nm. Ratios from 3:1 to 36:1 can be found.
Low backlash: ≤30 arc/min. at input
Input speeds because high as 3,000 RPM
Precision machined aluminum housings
Dual ball bearings upon all shafts
Available in ratios from 3:1 to 36:1
Output torques as high as 380Nm
Speed Increaser Gearboxes
Our low ratio Encoder gearboxes and inline taper gearboxes may also be used as gear rate increasers, if needed.
The Ever-Power Advantage: 30 years of Unparalleled Quality
Greased for life
Input speeds since high as 4,000 RPM
Available with gear ratios up to 3600:1
Customized gearboxes available
Fully machined from block housings
Ball bearings upon all shafts
Ever-Power offers a wide selection of misalignment shaft couplings in in . and metric bore sizes. Inch and metric Precision Ground Shafts can be found from stock.

GEARBOX REDUCERS
Correct angle gearboxes (worm and planetary) are durable 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. Contact our technical sales personnel for help determining which gearbox alternative is most beneficial for you.
