◆High Precision Machining:CNC（Computer Numerical Control）ma-chining enables extremely high precision, typically controlled within+0.01mm or better, resulting in finely crafted products with longlifespans.Traditional casting processes are influenced by variousfactors, leading to relatively low dimensional accuracy and shortproduct lifespan. Cast parts tend to have relatively rough surfacesand may contain defects such as sand holes and air pores.
◆The knee joint features original U.S-imported INA sealed needleroller bearings, significantly extending its service life more than threetimes that of standard knee joints.
◆Dual valve extension and flexion pneumatic system will change the speedof walking by the users' needs with a smooth and natural gait.
◆The swing and flexion of knee joint is similar to human knee joint, whichprovides a natural gait.
◆Incorporates a unique knee joint locking function imitating the humankneejoint to ensure that the prosthetic knee operates safely in heel strikephase and stance phase like a human knee.In take-off phase, the pros-thetic kneecan imitate the human knee function to walk easily and natu-rally with kneeflexion.
◆Multi-axial knee joint design to achieve balanced load break for the rota-rybearing in the stance phase and substantial increase in service life ofthe kneejoint body.
◆Differentiated full-sealed needle bearing knee joint design that differsfrom the conventional ball bearing or bushing design currently availableon the market.
