Inline Planetary Equipment Reducer Options
Gearboxes are known by many different brands, including gear drives, reducers, equipment reducers, quickness reducers, and gearmotors. All terms 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, lightweight spur gear inline planetary equipment 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 ranging 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, light-weight, low backlash gear drives were created particularly for encoder applications. They have a very low minute 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 are available, 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 speeds up 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 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 limited, 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 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 really rugged and compact. These planetary gearboxes possess fully-machined housings (light weight aluminum or steel), and are outfitted with ball bearings throughout. Our inline planetary equipment reducers offer flexible electric motor mounting options and can 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 on all shafts
Obtainable in ratios from 3:1 to 36:1
Output torques as high as 380Nm
Speed Increaser Gearboxes
Our low ratio Encoder gearboxes and inline taper gearboxes may also be used as gear quickness increasers, if needed.

GEARBOX REDUCERS
Correct 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. Contact our technical sales staff for help determining which gearbox alternative is most beneficial for you.
