Inline Planetary Equipment Reducer Options
Gearboxes are known by many different names, including equipment drives, reducers, equipment reducers, swiftness reducers, and gearmotors. All terms can be used pretty much interchangeably when refering to inline planetary equipment 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 installed to motors or used with shaft coupling. Ratios from 2:1 to 625:1 are available, with torque values which range from 0.13Nm to 90Nm.
Input velocity: up to 4,000 RPM
Precision machined aluminum housing
Dual ball bearings on all shafts
Encoder Low Backlash In-Line Gearboxes
These compact, light-weight, low backlash gear drives are designed specifically for encoder applications. They have a very low moment of inertia at the shaft insight, and so are rated for input boosts 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 are available from stock.
Result torque: 1 oz.-inch
Backlash: 15 arc-minutes (at any ratio)
Ratios from 4.96:1 to 3600:1
Input boosts 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 gear reducer boxes with backlash equal to or better than 8 arc/minute. These inline gearboxes are made for applications where space is limited, and are available either as a shaft insight or mounted 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 really rugged and compact. These planetary gearboxes possess fully-machined housings (aluminum or steel), and so are outfitted with ball bearings throughout. Our inline planetary equipment reducers offer flexible electric motor mounting options and will deliver result torques up to 380 Nm. Ratios from 3:1 to 36:1 are available.
Low backlash: ≤30 arc/min. at input
Input speeds since high as 3,000 RPM
Precision machined aluminum housings
Dual ball bearings on all shafts
Available in ratios from 3:1 to 36:1
Output torques since high as 380Nm
Speed Increaser Gearboxes
Our low ratio Encoder gearboxes and inline taper gearboxes may also be utilized as gear speed increasers, if needed.
The Ever-Power Advantage: 30 years of Unparalleled Quality
Greased for life
Input speeds as high as 4,000 RPM
Available with gear ratios up to 3600:1
Customized gearboxes available
Fully machined from block housings
Ball bearings on all shafts
Ever-Power offers a broad collection of misalignment shaft couplings in inch and metric bore sizes. ” and metric Precision Surface Shafts can be found from stock.

GEARBOX REDUCERS
Correct 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 efficiency is important.
