At Bos, we care about you and your company. We specialize in custom hydraulic cylinder customization, material selection, and manufacturing, and provide excellent service according to your needs.




The compact design and rugged construction of our Welded Hydraulic Cylinders make them indispensable across a wide range of sectors. In construction and mining equipment, they power excavator arms, bulldozer blades, and rock breakers, enduring intense shock loads and abrasive environments. The agricultural sector relies on them for tractors, harvesters, and plows, where space constraints and reliability are critical. Industrial automation systems, including robotics, injection molding machines, and material handling equipment, benefit from the cylinders’ precise control and leak-resistant performance. Additionally, their use extends to aerospace, where they actuate landing gears, and to renewable energy systems, such as hydraulic pitch controls in wind turbines. This broad applicability underscores our ability to customize Welded Hydraulic Cylinders for diverse operational needs, whether involving extreme temperatures, corrosive conditions, or high-speed cycles.


Choosing our Welded Hydraulic Cylinders translates into tangible benefits for equipment manufacturers and operators. Firstly, their compact and lightweight design allows for easier integration into machinery with limited space, without compromising power density. Secondly, the welded construction offers superior strength and fatigue resistance, reducing the risk of structural failure under prolonged high-pressure operation (e.g., up to 3,000 psi as seen in industry standards) . Third, these cylinders require minimal maintenance due to fewer external parts and advanced sealing systems, which mitigate leakage and extend service intervals. Finally, their adaptability to harsh environments**—achieved through specialized coatings, stainless-steel materials, or custom port configurations—ensures consistent performance in settings plagued by contaminants, moisture, or temperature fluctuations.
