With years of experience in manufacturing Custom Hydraulic Cylinder, we provide customer satisfaction through manufacturing and customization.
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 practical and cost-effective nature of our Single-Acting Hydraulic Cylinder makes it an indispensable component across a remarkably diverse spectrum of industries. In the agricultural sector, they are the workhorses behind tractor implement lifts, plow controls, and gate actuators on machinery, where their reliability and simplicity are paramount. The material handling and manufacturing industries deploy them extensively for clamping, pressing, and ejection operations, where a powerful, held position is needed. Construction equipment utilizes these cylinders for jacking systems, stabilizer legs, and simple lifting applications. Beyond these, you will find our Single-Acting Hydraulic Cylinder in recycling balers, as actuators for hydraulic jacks, and within various automation systems where a fail-safe retraction is required. This broad applicability underscores our ability to provide both standard and highly customized solutions, whether the requirement involves specific mounting styles, unique stroke lengths, or specialized rod coatings for extreme conditions.


Our manufacturing capabilities are designed to meet a wide array of technical demands. We produce Single-Acting Hydraulic Cylinders with bore sizes typically ranging from 20mm to 200mm and standard operating pressures up to 210 bar, with high-pressure options available. The piston rods, crafted from our high-quality Hard Chrome Plated Piston Rod stock, are available in various diameters and can be supplied with surface hardness up to HRC 60-65. Standard stroke lengths can be tailored to application needs, and we offer a variety of mounting styles, including clevis, flange, and foot mounts. To address the diverse needs of the market, we produce several distinct types of Single-Acting Hydraulic Cylinder: the Spring-Return Cylinder, which uses an internal spring to automatically return the piston; the Gravity-Return or Load-Return Cylinder, which relies on an external force for retraction; the Plunger Cylinder or "ram," which has no piston and is ideal for high-thrust applications; and the Displacement Cylinder, often used in specialized applications like hydraulic jacks. Each type can be further customized, ensuring you receive the perfect Single-Acting Hydraulic Cylinder for your specific challenge.
