Ever-Power offers standard and customized in-collection gearboxes to meet up the needs of almost any movement or power transfer application. Our inline gearboxes are designed for low backlash functionality. They are precision built to provide reliable assistance in even the the majority of demanding operations.
Read “10 Points to Consider to have the Gearbox You Need” for assistance in finding the best and most effective gear reducer option for the application. “Inertia and the usage of Inertia Figures” has an 
example and a method for coping with inertia in gearbox selection.

Inline Planetary Gear Reducer Options
Gearboxes are known by many different titles, including gear drives, reducers, equipment reducers, rate reducers, and gearmotors. All conditions can be used more or less 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 could be direct installed to motors or used in combination with shaft coupling. Ratios from 2:1 to 625:1 can be found, 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 were created specifically for encoder applications. They employ a low moment of inertia at the shaft insight, and 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 are available from stock.
Output torque: 1 oz.-inch
Backlash: 15 arc-minutes (in 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 equipment reducer boxes with backlash add up to or better than 8 arc/minute. These inline gearboxes are designed for applications where space is limited, 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 input 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 type of internal epicyclic servo reducers are extremely 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 motor mounting options and may 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 since 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 since high as 380Nm
Speed Increaser Gearboxes
Our low ratio Encoder gearboxes and inline taper gearboxes may also be used as gear acceleration increasers, if needed.

GEARBOX REDUCERS
Correct angle gearboxes (worm and planetary) are tough and built for 90° turns. Inline reducers (parallel shaft and planetary) are an ideal match for motors with high insight speeds, or when gearmotor performance is important. Get in touch with our technical sales staff for help identifying which gearbox answer is most beneficial for you.
