Planetary gear units
Planetary gear units to the SPN standard
SPN planetary gear units excel due to their wide range of possible applications. High rigidity combined with low radial backlash for their dynamic positioning role. A highly efficient, compact design for continuous operation of your smart solution. Or optimal smooth running properties through ground helical gears. What do you consider to be important when selecting a gear unit? You decide which requirements your gear unit should fulfil.
SPN planetary gearboxes are easy to customize, even for special applications. Complete special transmissions for many industries and exceptional requirements can also be developed and produced. Our process for the special transmission is transparent and cost-conscious. See for yourself.
The common practice in SPN is to adapt standard gears, as in this case. In an example in food processing, compliance with hygiene standards was anchored in the requirements for the planetary gearbox.

Basic design of planetary gear units
The basic design of a planetary gear unit consists of a sun gear, a ring gear and several planetary gears. The planetary gears are supported by the ring gear and rotate around the sun gear. This operating principle gave the name to this type of gear unit. The gear unit's drive and output functions can be performed by the sun gear, the housing or the planetary carrier, depending on the design.
In the most common design, the epicyclic gear unit, the drive function is performed by the sun gear, the output function by the planetary carrier, and the housing is stationary. This design has a positive influence on the internal forces in the gear unit. The load distribution over several planetary gears enables high torques to be transmitted in a compact design. The use of helical gears reduces the running noises.
These are the advantages of planetary gear units to the SPN standard

E- P88-S-VA planetary gear unit - keeping you clean
GOOD TO KNOW
The gear unit was developed for applications from the hygienic sector. Due to the seamless design and the choice of materials, the gear unit can be used process-integrated in the Hygienic Design Zone.
YOUR BENEFITS
- high corrosion protection - external components are made of stainless steel 1.4404
- operating temperature below 60°C in S1 operation due to finely tuned part systems
- high flexibility due to different gear ratios
Planetary gearhead X- P118-F-DM - for more power
GOOD TO KNOW
This gearmotor unit has been specially developed for maximum power density. The direct connection between motor and gear unit saves overall length and mass inertia. This allows the unit to be operated particularly dynamically.
YOUR BENEFITS
- compact design due to direct motor attachment
- low inertia - coupling parts between motor and gear unit are not required
- High rigidity due to optimally dimensioned flanged shaft
PU4 planetary gear unit - light-footed powerhouse
GOOD TO KNOW
The planetary gear units of the PU4 series stand for power density. The use of modern materials in combination with innovative ideas makes for a gear unit of contrasts. A powerhouse that impresses with its lightness. Powerful in performance data but still with the best values for mass inertia. Technically at the highest level.
YOUR BENEFITS
- high acceleration - thanks to an inertia-optimized motor connection
- high torque - due to wide, double-bearing planetary gears
- high rigidity - due to large shaft dimensions
- high permissible radial forces - due to tapered roller bearings with optimized bearing spacing
- Low torsional backlash - due to paired drive components
- low running noise - due to ground helical gearing
- easy motor mounting - due to tangential clamping with sun gear fixation
- variable - due to any mounting position
- maintenance-free - due to lifetime lubrication with synthetic gear oil
- low energy consumption - due to high efficiency
RC4 planetary gear unit - the plus in rigidity
GOOD TO KNOW
The planetary gear units of the RC4 series are designed with a flanged shaft. The solid flanged shaft exhibits high torsional stiffness and is thus particularly suitable for positioning tasks. Fittingly, the radial backlash is less than one minute of arc. RC4, the gear unit that cuts to the chase.
