安全锁紧装置  制造商、经销商、供应商

For more than forty years we have been manufacturing protective systems for the world's machinery building sectors. Our first products were bellows and coil springs that we produced in Seligenstadt, which is still our head office today. Through consistent further development we expanded our production to several sites in Germany and abroad for most efficient service to our customers worldwide.
Protection and window systems
Through a consistent development of our first range of products - bellows for the protection of linear guides - we engineered the SAMURAI range of product, lamella protected bellows and aprons and also complete backwall systems.
In addition to spiral springs other products such as telescopic steel covers, roller systems, machine safety windows.
VISIPORT® Spin windows and LED lighting systems complete our range of offers.
Clamping and Braking Systems
Within the last ten years we also enlarged our second sphere of competence which new includes pneumatic and electromagnetic clamping and braking systems and also manual and mechanical clamping systems.
Research and Development
This product diversity is possible only with extensive research and development as well as intensive detailed work. In close collaboration with external institutes developments and structures are tested for their practicability and extreme situations simulated so that our products can also fulfil the high requirements in the field.
Quality
Our own product and process quality is verified by regular certification procedures: all of our European production locations have been awarded DIN ISO 9001:2015 certifications. Kaizen teams at all works contribute towards continuous improvement.
Innovation never ends - in this spirit we will keep on working on innovations and improvements for our customers.

Safety solutions for linear motion in mechanical engineering
SITEMA is the only company worldwide specializing in the development and production of clamping units and linear brakes acting on round rods. The deliberate focus on these often safety relevant products makes SITEMA a competent realistic and powerfull system provider with a wide range of products that offer the optimum solution for every application.
With the experience that comes from more than 160‘000 clamping units
Following its foundation in 1979, SITEMA developed the first system worldwide generating the necessary high braking forces directly at the surface of the lifting cylinder shaft. This new technology formed the basis for perfecting clamping devices for a wide range of tasks. Then as now, our watchword is: absolute functional safety.
