Hirth serration rings
Standard and tailor-made diameters
Whether it is a standard size that is always in stock or a tailor-made serration ring, our Hirth serration rings are the ideal positioning element. Hirth serrations enable you to position your workpieces or products with positive locking and with the highest precision enabling you to produce parts of the highest quality standards while achieving maximum productivity levels.
Applications
Primarily used to position rotationally symmetrical components in the machine tool industry and in general mechanical engineering, it is also possible to use a Hirth serration ring as a connection component, typical applications include:
- Rotary indexing tables, turret heads and disk turrets in machine tools
- Connections in metrology, robot technology and medical technology
- Connections in aerospace technology
- Shafts, wheels and rotors in gear units, pumps, fans, compressors and turbines
- Technical applications
Customized serration service
Machining of a Hirth serration onto customer supplied components
Flexible in terms of your requirements
Applying customized serration to your equipment can be achieved up to a diameter of 1,600 mm.
Connecting components with high strength and precision
The customers’ machine component receives a Hirth serration. This component then can connect and precisely position shafts, wheels, disks, cranks and other parts in many areas of mechanical engineering to one another.
Applications
Typical applications are usually found in the machine tool industry and in general mechanical engineering markets, however other applications include:
- Shafts, wheels and rotors in gear units, pumps, fans, compressors, turbines and rolling mills
- Rotary indexing tables, turret heads and disk turrets in machine tools
- Connections in gas and steam turbines
- Flanged connections on shafts
- Connections in metrology, robot technology and medical technology
- Connections in aerospace technology
- Crank or joint shafts
- Substitution of complex, single-piece forged parts
