Inline Planetary Gear Reducer Options
Gearboxes are known by many different titles, including gear drives, reducers, gear reducers, rate reducers, and gearmotors. All conditions 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, lightweight spur gear inline planetary gear reducers. These inline gearboxes could be immediate installed to motors or used with shaft coupling. Ratios from 2:1 to 625:1 can be found, with torque values which range from 0.13Nm to 90Nm.
Input quickness: 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 have a very low minute of inertia at the shaft insight, and are rated for insight 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 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 equipment reducer boxes with backlash equal to or much better than 8 arc/minute. These inline gearboxes are designed for applications where space is bound, and are available either as a shaft input 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 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 equipment reducers offer flexible motor mounting options and can 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 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 swiftness 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. Contact our technical sales staff for help identifying which gearbox alternative is most beneficial for you.
