IMO slew drives and slewing rings

IMO is a leading manufacturer of large diameter antifriction bearings and ready-to-install self-contained slew drives. Since 1988, we've been supplying satisfied customers with slewing rings and slew drives that meet their usage needs perfectly - "made in Germany" quality.

Standard versions

At our production location in the south of Germany, we produce standard versions of ball slewing rings, roller slewing rings, and ball-roller combination slewing rings with dimensions ranging from 100 to 6,000 mm. We developed and patented our first slew drives in 1993. Today, our ready-to-install units with spur gear unit or worm drive are available in a wide range of standard series.

Customer-specific versions

However, we focus on tailored customer solutions. IMO engineers and application technicians can provide you with comprehensive advice and work with you to develop the ideal slewing ring and perfect slewing solution for you.

For more than three decades, IMO slewing rings and slew drives have been proving their worth in the most varied of application areas. We've been supplying products to many of our customers for decades. We'd love to have the opportunity to win you over with our technological competence, too!
