With years of experience in honing tube manufacturing, we deliver customer satisfaction through both manufacturing and customization.
At Bos, we care about you and your company. We specialize in honing tube customization, material selection, and manufacturing, and we offer superior service tailored to your needs.




Choosing our Chrome Plated Honed Tubes is an investment in operational uptime and reduced total cost of ownership. The advantages are direct and significant.
Exceptional Wear and Abrasion Resistance: With a surface hardness typically exceeding 900 HV, the plated surface dramatically resists wear from piston rings and seals, and is highly resilient to abrasive contaminants in the hydraulic fluid.
Permanently Low Friction Coefficient: The naturally low friction of chrome reduces stiction and running friction, leading to smoother cylinder operation, higher mechanical efficiency, and reduced heat generation within the system.
Extended Service Life and Reduced Downtime: By simultaneously combating wear and corrosion, these tubes outlast standard honed tubes by a significant margin, translating into fewer replacements, less unplanned downtime, and lower long-term maintenance costs.


Our position as a trusted Chrome Plated Honed Tubes Supplier is built upon a foundation of specialized expertise and an uncompromising quality assurance regimen. We understand that a successful chrome plating is entirely dependent on the quality of the underlying honed substrate. Our vertical integration allows us to maintain strict control over both the honing and plating processes. We employ advanced controlled-depth plating techniques to ensure a uniform, consistent chrome layer that is free from micro-cracks, porosity, or delamination risks.
Furthermore, our technical team provides more than just a product; we offer application-specific guidance. We help our clients determine the optimal combination of substrate material, honing finish, and chrome plating thickness for their specific pressure, corrosion, and wear challenges. This collaborative approach ensures that the Chrome Plated Honed Tubes you receive are not just an off-the-shelf component, but a custom-engineered solution designed for maximum performance and longevity.

Honed tubes are finished using abrasive stones that create a precise, cross-hatched surface, while SRB tubes are processed using a cutting tool (skiving) followed by a burnishing roller. Honed tubes generally provide better surface finish and straightness, while SRB tubes can be more cost-effective for certain applications.
