Core Features
Constructed with high-quality Nylon and POM materials, this miniature 624ZZ pulley delivers excellent wear resistance and stable structural performance. The built-in dustproof bearing guarantees long-term low-noise and stable operation. Precision U-groove design prevents slipping and running deviation. Compact non-standard 4*18*6mm size is ideal for ultra-narrow and customized installation spaces.
Material Advantages
Nylon: Lightweight, impact-resistant and cost-effective, perfect for general light-load silent sliding applications.
POM: Features high rigidity, low friction and great dimensional stability, suitable for high-frequency continuous operation. Both materials reduce noise and mechanical wear compared with conventional metal pulleys.
Application Scenarios
This custom 624ZZ Nylon And POM U-type pulley is widely applied in miniature automation devices, precision linear slides, small sliding mechanisms, micro packaging equipment and compact custom mechanical systems.
