With FLENDER SIP planetary gear units, we offer you a spectrum of fatigue-resistant, reliable and finely spaced gear unit solutions. The series includes not only the highly integrated planetary gear motor but also maximum conformity with all international motor standards and ensures that quality and performance bear a sensible relationship to life cycle costs and price.
The SIP series of Flender gear units covers a wide range of different gear unit models: eight frame sizes, six transmission ratios and five output shaft versions. To ensure that the gear units can be installed in any application, a number of options are available: cylindrical shafts with parallel keys or splines, hollow shafts with shrink disks or splines and flanged shafts.
Coaxial and 90° FLENDER SIP gear units offer a very finely spaced spectrum of transmission ratios with up to 53 steps. The accessory program provides all the necessary connecting adapters for standard motors, including connections to IEC and NEMA motors as well as to servomotors.
Furthermore, temperature control, explosion protection, taconite seals, a design for temperatures down to –40 °C and various mounting options guarantee optimal availability and fail-safe operation even under demanding ambient conditions.
With FLENDER SIP, reliability and flexibility become a product. Benefit from the special FLENDER SIP qualities in the premium league and get the efficiency you want.

With our Flender PLANUREX 3 planetary gear units we redefine the expectations. PLANUREX 3 stands for a new generation of extremely power-tight, multi-purpose premium planetary gearheads.
PLANUREX 3 gearboxes offer a complete, fully standardized planetary gear unit portfolio for horizontal installation in L and XL dimensions, combined with short delivery times worldwide, an excellent price/performance ratio and very high modularity. The concept strikes the optimum balance between power density, availability and costs.
Since plants are often operated at their design limits and beyond, our Flender gear units have to withstand the highest loads as well as enormous axial and radial forces. With Flender gear units PLANUREX 3, we therefore offer extremely compact premium drive solutions that meet the high requirements of continuous operation and promise you maximum operational reliability even under discontinuous loads with a double overload capacity compared to the nominal torque. This new gear generation not only offers the highest power density, but also extremely robust gear units and makes a decisive contribution to the availability of your work machine.
This Flender planetary gear units offer you various options for optimally adapting the gear unit to the requirements of your application, e.g:
Gear unit base for base mounting
Torque shaft support
Support 2 (Chun version)
Connection for oil cooling
