Frequently Asked Questions

What is the SMC JAF20-8-125 floating joint used for?

The SMC JAF20-8-125 floating joint compensates for misalignment between a pneumatic cylinder rod and the driven load. It prevents side-load damage to the cylinder seal and rod, extending actuator life in automated machinery, packaging lines, and material handling systems.

What are the specifications of the SMC JAF20-8-125?

The SMC JAF20-8-125 is a brass floating joint with an M8 x 1.25 thread size, designed to fit a 20 mm bore diameter pneumatic cylinder. The manufacturer part number is JAF20-8-125. It is part of the SMC JA Series for pneumatic actuator connections.

Where to buy the SMC JAF20-8-125 floating joint worldwide?
