Inline Planetary Gear Reducer Options
Gearboxes are known by many different brands, including gear drives, reducers, equipment reducers, swiftness reducers, and gearmotors. All conditions 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 gear reducers. These inline gearboxes could be immediate mounted 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 swiftness: up to 4,000 RPM
Precision machined aluminum housing
Dual ball bearings upon all shafts
Encoder Low Backlash In-Line Gearboxes
These compact, light-weight, low backlash gear drives were created particularly for encoder applications. They employ a low minute of inertia at the shaft input, and so are rated for insight 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 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 boosts to 3,000 RPM
Diameter: 1-1/16” or 1-3/4”
Black anodized aluminum housing
303 stainless steel gears and shafts
Ball bearings
Low Backlash Inline Taper Gearboxes
Our taper gearmotors are inline planetary gear reducer boxes with backlash add up to or much better than 8 arc/minute. These inline gearboxes are designed for applications where space is bound, and are obtainable 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 have fully-machined housings (aluminum or steel), and are outfitted with ball bearings throughout. Our inline planetary gear reducers offer flexible engine mounting options and will deliver output torques up to 380 Nm. Ratios from 3:1 to 36:1 can be found.
Low backlash: ≤30 arc/min. at input
Input speeds as high as 3,000 RPM
Precision machined aluminum housings
Dual ball bearings upon all shafts
Obtainable in ratios from 3:1 to 36:1
Output torques because high as 380Nm
Speed Increaser Gearboxes
Our low ratio Encoder gearboxes and inline taper gearboxes may also be utilized as gear rate increasers, if needed.
The Ever-Power Advantage: 30 years of Unparalleled Quality

GEARBOX REDUCERS
Right 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 insight speeds, or when gearmotor efficiency is important.
