Protective bellows for machinery
The bellows adapt to the movement of the mechanism they accompany, expanding or contracting.
The protective bellows are designed to protect people, machines and articulated systems that are located next to them. The bellows adapt to the movement of the mechanism they accompany, expanding or contracting.
Advantages of our protective bellows
- Personalization : We offer HEMA brand bellows in a variety of designs tailored to your application, whether with special materials for laser, plasma, or welding applications, special versions for medical technology, or designs for high-speed applications.
- High product quality : The bellows have been subjected to extensive product and material testing to ensure their quality.
- Comprehensive protection We have a wide range of bellows products, from individual bellows to complete systems ready to install as a rear wall for the machine, with their guides and accessories.
Elastic bellows
Elastic bellows—or accordion-shaped bellows—are used, for example, for applications in lifting tables or general machinery guides. We also offer round, stitched bellows as an alternative to spiral metal springs. to protect shafts, bars and spindles .
He Laminated bellows It is very durable and stable due to its combination of materials. As a bellows for cutting machines (laser, plasma or waterjet), the Elastic bellows protects mechanical components such as spindles and guides, as well as protecting the laser beam.
The Elastic series It can be combined in various ways. The basic components, as well as the material, shape, processing type, and dimensions, are individually tailored to your needs.
Samurai Bellows
The special feature of the “Samurai” bellows series are the l metallic amines that bind to the upper edge of the folds They reinforce the bellows and protect it from hot or sharp chips, acting as a guard. Thanks to this protection, the Samurai series is well-suited for HSC applications.
Bellows W
Modern machines are becoming increasingly compact, leaving little room for protective covers. With the W bellows, we meet two important requirements: on the one hand, These bellows require less installation space than conventional models and, on the other hand, they manage to cover longer courses.
W bellows require fewer pleats to achieve the same extended length. This material savings reduces the space required for the compressed bellows.
Another advantage of the W bellows is its weight: since it does not require support frames, It is lighter than standard systems and allows for better dynamics in the movement of the axes.
Bellows for special applications
For applications with special requirements we also offer bellows made of soft PVC , rubber discs, or coated fabrics. Soft PVC bellows are resistant to oil, alkalis, and acids, as well as water and dust.
Our rubber disc bellows They are of the highest quality. They are also visually the most attractive protective covers for pistons and spindles. They are also designed to be leak-proof.
We recommend the use of rubber fabric bellows If the bellows are particularly subject to intense wear, high pressure conditions or high temperatures of up to 200 °C.
Roofs
If the processing space of the machines is not closed during the manufacturing process, Chips and machine coolants can seep in into the production environment and contaminate it.
Our roof covers are custom-designed for each machine, whether for initial setup or retrofit.
X-Velo Roof Covering System
The X-Velo roof cover retains both chips and coolant in the machine , avoiding contamination of the manufacturing environment.
This X-Velo system is suitable for both initial adaptation of the machine and for its update.
- Custom lengths up to 12 m. Customized solutions available upon request.
- High speeds of up to 75 m/minute
- Transparent and lightweight material
- No twisting thanks to our special fastening systems
- Easy to clean (open profile)
- The cover is easy to screw on. The screw thread runs through the entire profile.
- Guide rails are included with delivery
Rear wall system
Rear wall systems They protect sensitive machine parts from chips and coolants during the production process. The rear wall system is manufactured with bellows and delivered ready for installation on the machine. Installation times are significantly reduced, as the machine manufacturer no longer needs to assemble individual bellows, as they assemble a complete system.
To protect the axles, they are used bellows with stainless steel sheets , the so-called bellows " Samurai «.
All rear wall systems and their components are custom-designed for each machine and can reach travel speeds of up to 120 m/min.
