With years of experience in linear axis manufacturing, we provide customer satisfaction through manufacturing and customization.
At Bos, we care about you and your company. We specialize in the customization, material selection, and manufacturing of Hydraulic Cylinder Barrels, and provide high-quality services according to your needs.




Recognizing that hydraulic power is utilized across a vast spectrum of industries and machinery, we offer a comprehensive range of Hydraulic Cylinder Barrel types to meet distinct operational requirements. Our portfolio includes standard barrels for general industrial use, manufactured from reliable carbon steels. For applications involving higher pressures or more corrosive environments, we provide barrels crafted from high-tensile alloy steels. Furthermore, we specialize in producing custom-designed Hydraulic Cylinder Barrels with specific port configurations, unique mounting arrangements, or specialized internal coatings to address challenges such as extreme wear or chemical exposure. This diversity ensures that for every mobile or industrial hydraulic system, there is a perfectly matched barrel from our production line.


Choosing our Hydraulic Cylinder Barrel translates into tangible benefits for your equipment's performance and total cost of ownership. The foremost advantage lies in the exceptional surface finish of the honed interior, which directly correlates to prolonged seal life and reduced friction, thereby enhancing overall system efficiency. Our barrels exhibit superior pressure containment capabilities, a result of meticulous material selection and strict control over wall thickness uniformity. This ensures safe operation at maximum working pressures and provides a significant safety margin against pressure spikes. Furthermore, the geometric precision of our barrels—maintaining strict straightness and roundness tolerances—guarantees smooth piston travel, minimizes uneven wear, and contributes to the long-term alignment and health of the entire cylinder assembly.

Bore diameter depends on required force (F = P × A). Wall thickness is selected based on design pressure, safety factor, and buckling/deflection requirements. Follow manufacturer or engineering standards (e.g., ISO, DIN).
