ZL Pin Coupling
ZL Pin Coupling
The ZL Nylon Pin Gear Coupling is Binhao’s non-metallic alternative within the gear coupling family, offering a compelling blend of strength and maintenance-free operation. This coupling utilizes precision-molded nylon or high-density polymer pins and bushings in place of traditional metallic gear teeth to connect the two robustly machined metal hubs. The key advantage is the complete elimination of lubrication requirements, making the ZL series ideal for applications where grease contamination is a concern or where maintenance access is difficult. Furthermore, the polymer components contribute to reduced operational noise and provide effective electrical insulation between the connected shafts. While accommodating angular and parallel misalignment, the ZL coupling maintains a clean, balanced transmission suitable for moderate torque applications. Binhao’s rigorous QC process ensures the precise geometry of both the metal hubs and the polymer pins, making the ZL series a reliable choice for textile, food packaging, and light chemical equipment.
