Inline Planetary Equipment Reducer Options
Gearboxes are known by many different titles, including equipment drives, reducers, equipment reducers, quickness 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, lightweight spur equipment inline planetary equipment reducers. These inline gearboxes can be immediate mounted 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 swiftness: 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 particularly for encoder applications. They employ a low second of inertia at the shaft insight, and so are rated for input speeds up 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 equipment reducer boxes with backlash add up to or much better than 8 arc/minute. These inline gearboxes are created for applications where space is limited, and are offered either as a shaft insight 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 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 (light weight aluminum or steel), and so are outfitted with ball bearings throughout. Our inline planetary gear reducers offer flexible motor mounting options and will deliver output 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 on 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 can also be utilized as gear swiftness increasers, if needed.
The Ever-Power Advantage: 30 years of Unparalleled Quality
Greased for life
Input speeds because high as 4,000 RPM
Available with equipment ratios up to 3600:1
Customized gearboxes available
Completely machined from block housings
Ball bearings upon all shafts
Ever-Power offers a broad collection of misalignment shaft couplings in inch and metric bore sizes. Inch and metric Precision Ground Shafts are available from stock.

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