Inline Planetary Equipment Reducer Options
Gearboxes are known by many different brands, 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 full line of compact, lightweight spur equipment inline planetary equipment reducers. These inline gearboxes could be immediate mounted to motors or used with shaft coupling. Ratios from 2:1 to 625:1 are available, with torque values which range from 0.13Nm to 90Nm.
Input acceleration: 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 were created specifically for encoder applications. They have a very low instant of inertia at the shaft insight, and 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 can be found from stock.
