Industrial springs

H&R develops and produces springs for numerous applications in almost all areas of technology.

H&R stands for competence and flexibility in the field of industrial springs. From a simple ballpoint pen spring to springs for heavy duty purposes, we can put your wishes into practice. H&R develops and produces springs for numerous applications in almost all areas of technology. Our technical support by our engineers in the project planning phase, during dimensioning, material selection, spring calculation, analysis of the spring function and design support, together with implementation in production, ensures a tailor-made product. The relevant properties such as statics, dynamics, low relaxation, fatigue strength, temperature resistance, special (UV-resistant) corrosion protection, etc. are met depending on the specific requirements and quality specifications. In-house tests such as fatigue strength tests, crack tests and salt spray tests flank the quality in development and production.

Application range

  • aircraft industry, subway, cable car, trains, armaments industry
  • mineral oil industry
  • automobile industry
  • mechanical engineering, etc.
