Seiki 40R1377K Industrial Hydraulic Swing Clamp

Seiki 40R1377K Industrial Hydraulic Swing Clamp is a hydraulic clamp designed to hold workpieces securely in fixtures during machining, with a swing‑action clamp arm activated by hydraulic pressure to engage quickly and release just as rapidly. Built for industrial environments, it delivers repeatable clamping force across cycles, helping maintain part accuracy on milling and drilling operations. The 40R1377K model sits within Seiki's family of swing clamps, sharing a compact form and mounting compatibility that fits standard fixturing layouts. In practice, engineers use it in fixture setups where fast cycle times and stable workholding are essential, such as CNC milling centers, drilling stations, and automated production lines. To ensure correct integration, practitioners typically verify mounting pattern, stroke length, operating pressure range, and material specifications from the official datasheet for the 40R1377K variant, and confirm compatibility with existing fixtures and hydraulic supply.
