Wittenstein alpha supplier in Romania
Precision planetary gearboxes for servo drives
Headquarters: Igersheim, Germany
Who is Wittenstein alpha and what does it make?
Wittenstein alpha is the line of precision planetary gearboxes from the German manufacturer Wittenstein, headquartered in Igersheim. The servo gearbox range covers zero-backlash, coaxial and right-angle designs, for transmitting motion from a servo motor to a mechanical axis without loss of precision when the direction reverses. For customers in Romania working with servo drives we can quote both the gearbox on its own and the motor-gearbox assembly from the Wittenstein range.
What sets the alpha family apart is the range of torques and backlash covered by each line: the Galaxie G series, with no backlash at all, reaches torques of 350-6000 Nm on ratios of 24-301; the TP+ series covers ratios from 4 to over 300 and torques between 43 and 22000 Nm, with backlash of at most 1-3 arcminutes; the more compact NP and CP series hold torques of 17-800 Nm, while the RP+ and XP+ series cover the high- and medium-torque segments respectively, with high precision.
For Romania, one extra detail matters: Wittenstein has its own factory at Șura Mică, near Sibiu, opened in 2008, where mechanical parts and assemblies for the planetary gearboxes are produced — so this is not just a remote manufacturer, but a player with local production of components.
What do we supply from the Wittenstein alpha range?
| Product | Description |
|---|---|
| Galaxie G Zero-Backlash Gearbox | Planetary gearbox in which the backlash is eliminated by a special gear construction, not merely reduced to a small value. Ratios between 24 and 301, maximum torques between 350 and 6000 Nm, suitable for high-precision positioning axes where repeatability on reversal of the direction of rotation is critical. The customer must tell us the torque required by the application and the ratio wanted. |
| TP+ Series Coaxial Planetary Gearbox | Coaxial gearbox with low backlash, between 1 and 3 arcminutes, with ratios from 4 to over 300 and maximum torques between 43 and 22000 Nm — a range used on large servo drive axes in industrial robots or handling equipment. |
| RP+ Series Right-Angle Planetary Gearbox | Gearbox with the output shaft perpendicular to the input, with ratios of 4-220 and maximum torques between 352 and 10450 Nm, backlash of at most 1-3 arcminutes. Useful where the mounting space requires a change in the direction of transmission, as on some manipulator axes or rotary tables. |
| NP/CP Series Compact Planetary Gearbox | Compact gearboxes, with ratios of 3-100 and maximum torques between 17 and 800 Nm, with backlash of up to 8 and 12 arcminutes respectively, sufficient for secondary axes where cost matters more than extreme precision. |
Why Wittenstein alpha?
- The Galaxie G series eliminates backlash completely, useful on positioning axes where repeatability matters more than speed
- Wide torque range, from 17 Nm (CP series) to over 22000 Nm (TP+ series), without changing the construction principle
- Coaxial and right-angle designs, chosen according to the mounting space available on the machine
- Local production of mechanical components at the Wittenstein factory in Șura Mică, near Sibiu, since 2008

How do we supply Wittenstein alpha in Romania?
We do not keep our own stock of gearboxes from the Wittenstein alpha range — we bring the product to you through EU supply channels, on order, usually in 1–4 weeks. We need the torque of the application, the ratio wanted and the orientation of the shafts for a correct quotation. The technical information comes from the manufacturer's technical documentation.
We check the availability of a specific gearbox size on request; units already installed by another supplier are serviced outside our quotation.
Frequently asked questions about Wittenstein alpha
What is the difference between the Wittenstein alpha TP+ and SP+ gearboxes?
TP+ covers torques of 43–22000 Nm and ratios of 4–302.5, while SP+ covers torques of 48–5700 Nm and ratios of 3–100, both coaxial, with backlash of up to 1–3 and 1–4 arcminutes respectively. The choice between the two depends on the torque, ratio and backlash required by the application.
How do I choose the right Wittenstein alpha planetary gearbox for a servo motor?
We start from the rated and peak torque required by the application, the ratio needed and the motor mounting type, then check the flange compatibility with the existing servo motor. The permitted backlash distinguishes the ranges: Galaxie G for zero-backlash applications, RP+ and TP+ for heavy loads, NP for economical solutions. The exact mechanical interface data is confirmed from the manufacturer's technical documentation.
Do you supply Wittenstein alpha gearboxes in Romania?
Yes, we bring in planetary gearboxes from the RP+, TP+, SP+, NP or Galaxie G ranges on order, depending on the exact code requested. We do not have our own shelf for this range, and the lead time is usually 1–4 weeks from the order (Wittenstein Alpha). It helps to send the mechanical interface drawing or the full code from the existing gearbox.
What is Galaxie G technology from Wittenstein alpha?
Galaxie G is a zero-backlash gearbox (0 arcminutes), with torques of 350–6000 Nm and ratios of 24–301. It is intended for applications where positioning precision and repeatability of motion must be kept constant. The range covers ratios and torques published by the manufacturer for various servo motor sizes.
How do I request a Wittenstein alpha quotation?
Send the Wittenstein alpha code from the nameplate and the quantity; we reply in English with availability and the lead time written in the quotation.
