APPLICATIONS

IMO inside

SAFE AND RELIABLE

IMO slewing rings for tunnel boring machines are customized solutions, mounted to be vibra-tion-resistant and impact-resistant in use. Temperature-resistant greases and seals defy the high temperatures and keep dirt and coarse particles away.
IMO slew drives with their closed housing and high load carrying capacity can be used in many tunnel boring equipment, too.

Tunnel boring machine (TBM)

3-row roller bearings with diameters up to 5 m are turning the cutting head right behind the shield.

Micro tunneling

These smaller three-row roller bearings are equipped with brass cages.

Ring erectors

Erectors use crossed roller or single row ball slewing rings for lifting and positioning the lining segments.

Tubbing lining

Differently constructed tubbing systems use a slew drive series WD-H, a worm driven modular system.
