PARAFLEX (Pin-and-Bushing Coupling)

This pin-and-bushing coupling features an aluminum alloy body, and the combination of high-precision pins and bushings (dry metal) minimizes backlash.Because it uses a universal joint design, shaft reaction forces caused by installation errors are extremely low, and the sliding motion between the pin and bushing friction surfaces also provides a damping effect.
