Planetary gear - properties

- High power transfer ratio in proportion to volume and mass

- Low backlash for exact positioning in automation applications

- Multiplication of torque with simultaneous reduction of speed

- Adapts the loads inertia to that of the motor for better dynamics in the drive system

- Smooth movement at high dynamic reversals (jerk-reduction in oscillating movements)

- Characterised by a high mechanic efficiency and are completely maintenance-free

SG - planetary gear

Economically favourable (price) and mechanically exact solution with gear ratios from 3 to 512.

Backlash 8 - 19 arcmin (SG-e line) och 6 - 22 arcmin (SG-se line).

Customer-specific mounting-flange and very short delivery time (some models are in stock)

Two series:

SG–e line (SG050, SG070, SG090, SG120 och SG155)

- Enhanced bearings for higher radial/axial load which allows for directly mounted loads on motor axis.

- low-friction bearings and optimised lubrication decreases heat emission at high speeds

- relatively low-price drive-solution

SG-se line (SG040, SG060, SG080, SG115 and SG160)

- lower inertia (internal mass lower than conventional gears) gives higher dynamics which is especially interesting for synchronised multi-axis systems

- strong, effective and high performance at a low price
