Blutref Bowden sheaths: versatility for every application

The Bowden sheaths, an invention from the 1910-1920s by Ernest Monnington Bowden, remains an essential solution for motion transmission in mechanical systems. Blutref, a leading company in the sector, offers a comprehensive range of high-quality Bowden sheaths designed to meet the needs of various industries, from automotive (e.g., window lifts and door openers) to marine, agriculture (mowers and tractors), and other industrial applications.

Features of Blutref’s Bowden sheaths

Blutref's Bowden sheaths, also known as "inner tube" sheaths, are made from top-quality materials that enhance resistance, smooth operation, and durability. Key features include:

Internal structure: the inner tube, which contains the cable, is made from high-performance materials such as high-density polyethylene (HDPE), acetal resin (POM), Teflon (PTFE), or HDPE with molybdenum disulfide (HDPE + MOS2). These materials ensure low friction and high wear resistance, essential for long-lasting applications.

Internal cable: the cables used with this product can be made of galvanized steel, stainless steel, or smooth or hammered variants. They are designed to resist corrosion, ensuring reliable performance even in harsh environments. The outer diameter of the cables typically ranges from 3 to 12 mm.

Wire rolling: the inner wire, made of carbon steel, undergoes a rolling process that gives it a rectangular shape, improving mechanical compression efficiency compared to traditional round wires.

External coating: the outer cable is coated with plastic materials such as low-density polyethylene (LDPE), polypropylene (PP), polyvinyl chloride (PVC), or nylon (PA). These coatings not only protect the internal steel structure but also allow for aesthetic customization, with a range of colors including white (ideal for strollers and sofa networks), and the classic gray and black, especially favored in bicycles and motorcycles, for both original and spare parts.

Advantages of Blutref’s Bowden sheaths

Blutref's products offer numerous benefits compared to traditional solutions:

Smooth movement: the inner tube’s low-friction materials allow the cable to move smoothly, reducing effort and enhancing the efficiency of the finished system.

Corrosion resistance: thanks to innovative materials, cables and internal wires are more durable in hostile environmental conditions.

Versatility: available in different sizes and materials, these products can be adapted for a wide range of industrial applications.

Customization: the external coating is available in various colors, creating a perfect mix of form and function.

Main applications of Bowden sheaths

Bowden sheaths find applications across a broad range of sectors, demonstrating their versatility and reliability:

Bicycles and motorcycles: used in brake and gear control systems.
Automotive: found in window regulation systems and other mechanical applications (doors, mirrors, and fuel caps).
Marine: used in control and transmission systems.
Agriculture: for equipment such as mowers, tractors, and other agricultural machinery.

Blutref provides not only high-quality Bowden sheaths but also flexible ropes, either galvanized or in stainless steel, perfect for creating flexible mechanical control systems. This combination ensures high compatibility and optimal performance.
