Shaft Phasing and Variable Speed Gearboxes

The benefits of these shaft-phasing gearboxes and variable-speed reducers include:

  • Low-Backlash

  • High-Durability

  • Wide Range of Models and Ratios

Right Angle – Series SP2

Right angle shaft phasing gearboxes are especially designed for applications requiring timing, positioning, registration or narrow-range speed control.

Double Planetary Inline – Series PD2

The Tandler series PD2 Double Planetary speed correction gearbox is a dual stage planetary gearbox part used for inline shaft phasing or narrow range speed control.

Single Planetary Inline – PE2

The Tandler series PE2 Single Planetary speed correction gearbox is a single stage planetary gearbox used for inline shaft phasing or narrow range speed control.

Mechanical Variable Speed Drives

Planetroll’s patented design offers several significant advantages over traditional friction drives and frequency inverters in applications requiring high torque at startup, explosion proof operation, infinite variable speed to zero RPM, and reliable overload protection.
