Line up（7）
| Model number | overview |
|---|---|
| LK4 | This is an Oldham coupling made of aluminum alloy hub and resin elements. It can accommodate large eccentricity and angular misalignment, with minimal axial reaction. Available in 7 sizes. Continuous torque 0.7 (N·m) to 36 (N·m). |
| LK5 | This is a metal plate spring coupling made of aluminum alloy. It uses a metal plate spring as the element, providing high rigidity, high flexibility, and is completely backlash-free. Available in 16 sizes. Allowable torque 0.25 (N·m) to 250 (N·m). |
| LK7 | This is a flexible coupling with slits processed on cylindrical material. It can accommodate large eccentricity and angular misalignment, and is available in aluminum alloy and stainless steel materials. Available in 8 sizes. Continuous torque 0.4 (N·m) to 35 (N·m). |
| LK8 | This is a coupling with a simple structure made of aluminum alloy hub and polyurethane elements. It excels in shock absorption and can be used for various applications. Available in 13 sizes. Continuous torque 0.7 (N·m) to 665 (N·m). |
| LK15 | This is a coupling made of a steel hub and stainless steel plate springs. It offers ultra-high rigidity and is suitable for high-precision operation. The attachment to the shaft uses a wedge fastening method, allowing for high-precision installation. Available in 7 sizes. Allowable torque 60 (N·m) to 800 (N·m). |
| LK23 | This is a coupling with an aluminum alloy hub and integrated damping rubber. It has excellent vibration absorption performance and is effective in countering oscillation of servo motors and resonance of stepping motors. Available in 7 sizes. Continuous torque 1.1 (N·m) to 18 (N·m). |
| LK24 | This is a plate spring coupling that employs a double clamp method on a steel hub. In addition to ultra-high rigidity, it is also very easy to install. It is suitable for connecting feed screws of machine tools. Available in 4 sizes. Allowable torque 60 (N·m) to 300 (N·m). |
