Inline Planetary Equipment Reducer Options
Gearboxes are known by many different brands, including gear drives, reducers, gear reducers, velocity 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 full line of compact, light-weight spur gear inline planetary gear reducers. These inline gearboxes can be direct installed to motors or used 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 upon all shafts
Encoder Low Backlash In-Line Gearboxes
These compact, light-weight, low backlash gear drives were created specifically for encoder applications. They employ a low second of inertia at the shaft insight, and are rated for input boosts to 3,000 RPM. Gear ratios from 4.96:1 to 3600:1 are available, 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 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 limited, 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 values from 1.14Nm to 12.7Nm
Epicyclic (Planetary) Servo Gearboxes
The Ever-Power line of internal epicyclic servo reducers are really rugged and compact. These planetary gearboxes have fully-machined housings (aluminium or steel), and are outfitted with ball bearings throughout. Our inline planetary equipment reducers offer flexible electric motor mounting options and may 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
Obtainable in ratios from 3:1 to 36:1

GEARBOX REDUCERS
Correct angle gearboxes (worm and planetary) are rugged and built for 90° turns. Inline reducers (parallel shaft and planetary) are an ideal match for motors with high input speeds, or when gearmotor efficiency is important. Contact our technical sales personnel for help determining which gearbox solution is best for you.
