Inline Planetary Equipment Reducer Options
Gearboxes are known by many different names, including gear drives, reducers, gear reducers, velocity 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 full line of compact, light-weight spur equipment 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 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 upon all shafts
Encoder Low Backlash In-Line Gearboxes
These compact, lightweight, low backlash gear drives are designed particularly for encoder applications. They have a very low instant of inertia at the shaft insight, and so are rated for input 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.
Result torque: 1 oz.-inch
Backlash: 15 arc-minutes (in any ratio)
Ratios from 4.96:1 to 3600:1
Input speeds up 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 created 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 line of internal epicyclic servo reducers are really rugged and compact. These planetary gearboxes have fully-machined housings (aluminium 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 as 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 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 since high as 4,000 RPM
Available with equipment ratios up to 3600:1

GEARBOX REDUCERS
Right angle gearboxes (worm and planetary) are rugged and built for 90° turns. Inline reducers (parallel shaft and planetary) are a perfect match for motors with high input speeds, or when gearmotor performance is important.
