Single Diaphragm Coupling D20 L20 – Compact Flexible Coupler
Single Diaphragm Coupling D20 L20 – Compact Flexible Coupler
Product Description:
The Single Diaphragm Coupling D20 L20 is a compact and flexible coupler designed for high-speed, precision applications such as CNC machines, robotics, and automation systems. With a rated torque of 2.1 N.m and a maximum torque of 3.5 N.m, this coupling efficiently compensates for parallel misalignments up to 0.02mm and angular misalignments of 1 degree, ensuring smooth operation even at high speeds up to 30000 rpm. The lightweight and compact design makes it ideal for space-constrained systems, while its durable construction ensures long-lasting performance.
