JCK Series Power Welding Clamp Cylinder
High-Torque Toggle Linkage Clamping System
Product Features
- Toggle Linkage Mechanism: Provides exceptionally high clamping torque (up to 800 N.m for Φ80) suitable for heavy-duty automotive and industrial welding applications.
- Self-Locking Function: The advanced toggle mechanism ensures the clamp remains securely locked in the clamped position even if supply air pressure is completely lost, greatly enhancing operational safety.
- Oval Piston Design: Utilizes a space-saving oval piston structure that minimizes the cylinder's width profile while maximizing effective force transfer.
- Manual Operation Option: Available with manual override handles (mountable on the Left or Right side) for easy setup, fixture adjustments, or emergency operation.
- Multiple Opening Angles: Supports a wide range of standard opening angles from 15° up to 135° to accommodate various complex workpiece geometries.
- Flexible Arm Mounting: Clamp arms can be mounted horizontally (standard) or vertically, with Left, Right, or Center mounting positions available to suit specific tooling setups.
