Higher torques in 7-series gear units

 Good news from our development department. By making small-scale optimizations and pushing known boundaries to the max, we have increased the torques for our large 7-series gear units. Your benefit – you get this increased torque at no extra cost.

More power for the big boys of the 7 series

Increased torque for our large 7-series gear units

We can offer increased torques in our gearmotors in combination with R..167, K..157, K..167 and K..187 without any parts changes at all. For F..157, all that is needed is for one shaft to be replaced.

Naturally, our increased torques also comply with all necessary safety requirements.

More torque for SPRIOPLAN®, too

Our development department is never idle – not even for our tried and tested products and solutions. For example, as a result of new calculations and the latest design criteria, we are able to increase the torque of our SPIROPLAN ® gear units W..10, W..20 and W..30.

Lubricants suitable for your gear unit

SEW GearOil increases the performance of SEW‑EURODRIVE gear units – be they standard, servo or industrial. It reduces the friction between gears by creating an excellent lubrication film.

Improved oil seal

The sinusoidal sealing lip of the new Premium Sine Seal exhibits substantially increased durability, and the new oil seal can be placed in the same location on the shaft during servicing.
