Detaljerad information

Grundläggande information

Grundläggande information

This is a new product with higher precision and durability than conventional products, and at a lower cost.
[Features]
·Shape with high torsional rigidity. Semi-permanent life with zero backlash.
·Absorbs lateral, angular, and axial misalignment. Stable even at high rotational speed with a low moment of inertia.
· The characteristics of forward/reverse rotation are the same and no repair is required. Excels in oil and chemical resistance.
·A structure that adjusts the misalignment of the axis by the deflection of a thin metal disk.
·It has a large transmission torque and supports high-speed rotation. Simple structure for easy attachment/removal.
[Applications]
·Servo motors, stepping motors, precision motors, etc.
·High-precision encoders, dynamometer drivers, high-speed and high-precision position control systems, centrifuges, copiers, etc.
