alpha SK+ / SPK+ Right Angle Precision Gearbox - Wittenstein Mechatronic Components and Systems for Motion Control

Offering excellent performance, the alpha SK+ offers various options when building your machines while enables the use of space-saving right angle servo gearboxes for many applications for which earlier coaxial gearboxes were necessary.

The hypoid gearset, which is the key innovation of the product, has three important advantages compared with the conventional bevel gear: it offers a higher torque because of the larger pinion, it makes cost savings possible because of high ratios in one stage and its noise is significantly lower due to the difference between straight cut and helical gear teeth in spur gear technology.
