FLENDER SIP Standard Industry Planetary Gear Units


Long-life top performance: The new planetary gear unit series for maximum process reliability

Cost-effective planetary gear units for highest requirements

When operating drives designed for limited life strength, it is often difficult to keep track of which drives have already reached or even passed the end of their useful lives. The more often you have to ask yourself how much longer your drive will continue to operate and whether you will get a replacement quickly if it fails, the more incalculable your own performance is.

Where costs, performance, and availability in the case of drives have to go hand in hand is where FLENDER SIP comes into its own.

Reliable performance

From now on, you need no longer do without proven Siemens quality. The technology of the FLENDER SIP series results in an extremely high-performance planetary gear unit which not only boasts an impressive price, but also offers very low life cycle costs as the decisive criterion for the user. Maximum reliability, practical versatility, and very high availability combine to create a gear unit solution to meet any and every customer requirement.

Long-life fatigue strength design

The maximum availability of your systems has long been at the center of our research and development work. For this reason, we have designed the FLENDER SIP series to be fatigue-resistant and long-lasting. Furthermore, the revolutionary design uses the highest quality component parts. For you, that means maximum reliability and sustainable performance.

Delivery performance

We can ensure high delivery reliability for FLENDER SIP in the long term. How do we do it? The FLENDER SIP concept consistently adheres to the principle of flexibility.
