Flexible bellows and protectors
for cylinders, machines, and lifting equipment
Bellows are versatile components used in a variety of industrial applications. They are primarily used to protect moving machine parts from dust, dirt and other contaminating or damaging elements, minimizing the risk of downtime and extending machine life.
In addition, bellows improve safety by preventing operators and other people from coming into contact with moving machine parts.
Bellows protect both the machinery and the operator
Choose bellows that fit your needs
The standard range of bellows at Betech includes four types. Each type of bellows has its unique properties and applications, making them suitable for a wide range of industrial applications:
- Cylindrical folding bellows
- Conical folding bellows
- Single folding bellows
- Rubber disc bellows
You get more benefits with good quality bellows
- The quality bellows Extends the life of the machine by shielding exposed parts from dust and dirt.
- The quality bellows Improves personal safety by preventing contact with moving parts.
- The quality bellows contributes to a beautiful, aesthetic whole in the machine design.
Folding bellows are versatile and durable
Folding bellows made from materials such as Molerit® or Chloroprene are the most common types. Molerit® is a unique thermoplastic rubber-like material with good chemical resistance. It is extremely weather resistant, but has limited resistance to oils and grease. Chloroprene, on the other hand, is weather resistant and has high acid and solvent resistance.
Rubber disc bellows are compact and efficient
Rubber disk bellows are designed to take up minimal space when compressed. They are made of rubber discs that are vulcanized together, making them extremely compact when the protected, moving machine part closes or contracts. These bellows are made of Chlorosulfonated Polyethylene (CSM), which is reasonably resistant to oil and chemicals and has exceptional weather resistance.
What material should you choose for your bellows?
The choice of material for bellows and flexible protectors depends on the specific application and environmental conditions.
Molerit®
Molerit® is a unique thermoplastic material often used for folding bellows due to its rubber-like properties and good resistance to chemicals.
The material is extremely weather resistant, making it suitable for outdoor applications. However, it has limited resistance to oils and grease, making it less ideal for applications involving these substances.
Chloroprene (CR)
Chloroprene, another common material for folding bellows, is weather resistant and has high resistance to acids and solvents, making it suitable for harsh environments.
It can withstand a wide temperature range, which also makes the material versatile for different applications.
Chlorosulfonated polyethylene (CSM)
Rubber disk bellows, on the other hand, are made from Chlorosulfonated Polyethylene (CSM), which is reasonably resistant to oil and chemicals and has exceptional weather resistance.
CSM is the common material used in rubber disk bellows, ideal for applications where the bellows need to take up as little space as possible when the motion mechanism retracts or closes and the bellows compresses.
Find your standard pods in the e-catalog
In our e-catalog you will find Scandinavia's largest online selection of the four popular types of bellows: Cylindrical folding bellows, conical folding bellows, single folding bellows (cuffs) and the compact rubber disk bellows.
Flexible and durable rubber bellows for automation, actuator, hydraulic cylinder, pneumatic lift, lifting and transportation equipment and other machine protection.
An integral part of the machinery
Bellows are increasingly being adapted and integrated into machine design. They not only protect moving parts, but also serve as ideal covers for various purposes. With their flexible folds, bellows can easily adapt to different sizes, giving the machinery an attractive finish.
Bellows, protectors and compensators customized to your design
In addition to the standard range of bellows, Betech also manufactures flexible bellows, protectors and compensators according to customer-specific requirements for size, material, shape and color. This gives you greater flexibility in design and application - and ensures that the bellows fit perfectly into the machinery and function optimally, providing your unique applications with optimal performance, protection and durability.
Custom bellows and guards can be designed to withstand specific environmental conditions and be a positive, contributing element to the aesthetic design of machinery.
Custom bellows and protectors will often be one of the following four types:
Molded rubber bellows and compensators
Molded rubber bellows and compensators are produced by compression molding in NBR, CR or other suitable rubber types in a mold tool. Due to the production method, molded bellows are most relevant for larger quantities and regular, recurring needs. Material selection, shaping and mold manufacturing is done in collaboration with Betech's product experts.
Rotated PTFE bellows and compensators
Turned PTFE bellows and compensators manufactured by turning PTFE are typically used in applications where the special chemical resistance or food contact approval of the PTFE material is critical. Material selection, design and manufacturing can be done with the help of Betech product experts.
Sewn bellows - Rod Protection Cover™
Sewn bellows - Rod Protection Cover™ - are typically used to shield hydraulic or pneumatic systems, protecting the piston rod from external particles and scratching, damaging impacts. A through opening in the long side and strong Velcro or strap closures ensure easy installation without the need to disassemble the cylinder and system.
Box bellows and mudguards
Square box bellows and vane guards are typically used in scissor lift applications where the environment needs to be protected on all sides from crushing and contact with the moving parts. Box bellows are also used for protection and shielding from moving vanes.
Get effective and versatile protection
One of the key benefits of bellows and flexible guards is their versatility. They can be used in a wide range of applications, from protecting moving machine parts to acting as a shielding cover for various mechanical applications. The materials and characteristic folded structure make it easy to customize the size of the bellows, making even standard bellows suitable for many industrial applications.
Safety depends on correct shape, size and material
Bellows play a crucial role in improving safety in industrial environments. By shielding or covering moving machine parts, they prevent operators and other people from coming into contact with these potentially dangerous parts. Therefore, an intact and properly fitted bellows helps to reduce the risk of injury. This makes them an essential component in any machine where people are near or around moving machine parts, mechanics and automation equipment.
