SEW-EURODRIVE is proud to introduce the WES Series stainless steel gear unit, a compact, hygienic drive solution that runs cool — even under continuous operation. Unlike worm gear units that overheat, the WES Series integrates SPIROPLAN right-angle gearing, ensuring smooth, reliable performance without excessive heat buildup.

Designed for food, beverage and other hygienic applications, the WES series is corrosion-resistant, easy to clean and rated for high-pressure washdowns.

Key advantages:
