Overview
The SMC J125-27-200-X4 floating rod joint is a pneumatic cylinder accessory designed to accommodate misalignment between the cylinder rod and the driven load. The floating joint series JA (standard) and JAH (heavy duty) can absorb any off-centering or loss of parallel accuracy between the cylinder and the driven body, making this component essential for applications where perfect alignment is difficult to maintain. The JA series standard type floating joint is used for pneumatic cylinders (Ø 180, Ø 200). This unit is offered in used condition and is fully functional for integration into existing pneumatic systems.
Key Features
- Absorbs off-centering and parallel inaccuracy of double-acting cylinders
- Reduces stress and premature wear on cylinder rod and load connection
- Simplifies system alignment requirements during installation
- Includes replaceable dust cover for joint protection
- Compatible with standard pneumatic systems and applications
