Hydro-lock Sleeves

SuperSource hydro-lock sleeves are a cost-effective solution for wood processing applications that require quick fastening and high precision self-centering of tools. The principle is to use the liquid medium to transmit the expansion force, between the inner ring of the expansion sleeve and the shaft, and between the outer ring and the hub. The generated surface tension between the two parts ensures the high-precision automatic centering and locking of the hub and the shaft. We offer two types of hydro-lock sleeves depending on the pressurizing modes, pressurized through Allen screws or a high-pressure grease pump. We provide various bolt connection setting to ensure compatibility of our product with the most machine in the market.
To meet the diversified market demand, we have continued introducing new products. We successively launched various high-end products such as SB3, SC3, AIL, and SQS2. With advanced processing, testing, and production management system, our products lead the industry in critical technical parameters such as concentricity and radial runout and have a cost-effective advantage over similar products in the market. Besides our standard products, we also offer a comprehensive range of custom products to meet any special requirements.

Pressurizing Systems

Pressure Screw Pressurizing system – Pressure setting and tools assembly are achieved by fastening the Allen screw on the hydro-lock sleeve using T-wrench. Loosening the screws to enable quick disassembly and replacement of the tools.

Grease Pump Pressurizing System – Use a high-pressure grease pump to set the pressure according to product specifications.

Assembly Mode

Interchangeable Assembly – Sleeve expands both inward and outward (i.e., the inner ring expands to clamp with the spindle and the outer ring expands to connect with the tools) to achieve automatic centering between spindle and tools. This assembly mode enables quick and easy change of tools.

Permanent Assembly (Inward Expansion) – Sleeve only expands inward to clamp with the spindle, while the sleeve and tools are connected through bolts. This assembly mechanism is structurally simple and the sleeves using this mode are typically smaller in size.

Permanent Assembly (Outward Expansion) – Sleeve only expands outward to be fastened with tools, while the sleeve and spindle are connected through bolts. This assembly mode is adopted for hydraulic expansion shafts and tool holders.
