WMH Herion – Drive technology and assemblies from Wolnzach
WMH Herion GmbH, based in Wolnzach (Bavaria), is a manufacturer and system supplier for precise drive technology, mechanical and mechatronic assemblies as well as environmental engineering machines. The company manufactures gear racks, spur gears, bevel gears, ball screw drives, gearboxes and drive elements – over 12,000 catalogue items from stock as well as custom-made products to drawing from one-off pieces to small series. Production includes in-house gearing technology with a gearing centre, machining, heat treatment such as case hardening and hardening and tempering, as well as assembly of assemblies and complete systems. Materials are steel (hardened and tempered, case-hardened), stainless steel, duplex steel, aluminium, plastics (POM) and castings. In addition to drive technology, WMH Herion manufactures environmental engineering machines such as the hook-liftable drum screen S-318, the air classifier WS 730 and twin-shaft shredders. The company serves more than 40 industries, including mechanical and plant engineering, machine tools, construction machinery, robotics, shipbuilding, stage technology and recycling.

Delivery & Support
Materials and manufacturing processes
Steel (hardened and tempered, case-hardened)
For spur gears, gear racks and sprockets under high mechanical loads.
Stainless steel
Use under corrosive conditions, including in environmental engineering.
Duplex steel
For applications in shipbuilding with increased corrosion requirements.
Plastic (Acetal/POM)
Plastic gears for low-noise, lubricant-free operation, e.g. in the sports industry.
Aluminium
Lightweight components for robotics.
Castings
Cast housings for gearboxes in agricultural and construction machinery.
Special steels / special materials
For applications with special load and environmental requirements, e.g. renewable energies.
