SMC Piston Rod Ball Joint, M12x1.25 Connection Size, 12mm Bore Size - KJ12D

This piston rod ball joint provides a swivelling rod-end connection for industrial actuators and linkages, designed to accommodate angular misalignment while transmitting linear motion. It is manufactured from steel and features a metric female connection suitable for integration with threaded piston rods in factory automation and heavy machinery. The component operates across a wide temperature span, making it appropriate for many process and environmental conditions.

Features and Benefits:

• M12x1.25 female thread enables secure metric attachment
• 12mm bore supports compact rod interfacing
• 32mm outside diameter offers robust bearing surface
• 22mm overall width ensures stable lateral support
• Operable from -20°C to 80°C for varied thermal environments
• Steel construction delivers high load capacity and wear resistance

Applications

• Suitable for pneumatic cylinder rod-end connections
• Ideal for hydraulic actuator linkages in industrial plants
• Used with gantry and positioning systems requiring articulation
• Can be used for robotic arm pivot points under load
• Used for agricultural machinery suspension link joints

What threading standard does it follow for compatibility?

It uses a metric thread format with an M12x1.25 female connection for mating with standard metric rod threads.

How does the material choice affect maintenance intervals?

The steel body increases resistance to mechanical wear, which typically lengthens inspection intervals under moderate contamination compared with softer alloys.

What operating temperatures should be expected for continuous service?

Continuous operation is suitable within the specified range from -20°C up to 80°C

exposure beyond these limits may reduce service life.

How does the component handle angular misalignment in linkages?

The spherical joint design permits articulation between the rod and mating component, allowing angular compensation while maintaining load transfer.
