Inline Planetary Equipment Reducer Options
Gearboxes are known by many different brands, including equipment drives, reducers, equipment reducers, velocity 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, lightweight 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 are available, with torque values which range from 0.13Nm to 90Nm.
Input rate: up to 4,000 RPM
Precision machined aluminum housing
Dual ball bearings on all shafts
Encoder Low Backlash In-Line Gearboxes
These compact, lightweight, low backlash gear drives are designed specifically for encoder applications. They have a very low instant of inertia at the shaft input, and so are rated for input 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.
Output 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 equipment reducer boxes with backlash add up to or better than 8 arc/minute. These inline gearboxes are designed for applications where space is bound, and are obtainable 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 extremely rugged and compact. These planetary gearboxes have fully-machined housings (light weight aluminum or steel), and so are outfitted with ball bearings throughout. Our inline planetary gear reducers offer flexible engine mounting options and can 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 because high as 3,000 RPM
Precision machined aluminum housings
Dual ball bearings upon all shafts
Available 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 can also be utilized as gear acceleration 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 equipment ratios up to 3600:1
Customized gearboxes available

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 input speeds, or when gearmotor efficiency is important. Get in touch with our technical sales personnel for help identifying which gearbox option is most beneficial for you.
