DIN Couplings

DIN couplings are mechanical shaft connectors manufactured in accordance with German Industrial Standards (DIN). They are designed to transmit torque between two shafts while compensating for misalignment. Known for their standardized dimensions, reliable structure, and good interchangeability, DIN couplings are widely used in machinery, automation systems, pumps, fans, and various industrial transmission applications.

Common types of DIN couplings include gear couplings (e.g., ZAPEX couplings), elastic couplings, diaphragm couplings, and universal joints. Gear couplings are ideal for high-torque applications with good misalignment compensation; elastic couplings are suited for medium and light-duty systems where shock absorption is needed; diaphragm couplings serve high-speed and high-precision drives. Based on different mechanical requirements, users can select the appropriate DIN model for safe and efficient torque transmission.
