Custom 625ZZ Nylon And POM U-Type Plastic Pulley | 5*25*7mm
The custom 625ZZ U-type plastic pulley is a non-standard precision grooved pulley available in Nylon and POM materials. Equipped with a double shielded dustproof 625ZZ steel bearing, this 5*25*7mm pulley delivers low-friction, smooth and quiet rotation for compact linear guide and light-duty transmission systems.
Product Specifications
Model: Non-standard 625ZZ U-Type Plastic Pulley
Overall Dimension: 5× 25× 7mm
Bearing Type: 625ZZ double metal shielded bearing
Optional Material: Nylon, POM (Acetal)
Structure: Embedded steel bearing + precision U-groove plastic body
Core Features
Made of premium Nylon and POM raw materials, this 625ZZ plastic pulley features outstanding wear resistance, anti-aging performance and stable structural rigidity. The built-in dustproof bearing ensures long-term low-noise and stable high-speed operation. Precision U-groove structure effectively prevents slipping and running deviation. Non-standard 5*25*7mm size perfectly fits custom and narrow installation spaces.
Material Advantages
Nylon: Lightweight, tough and impact-resistant with excellent cost performance, ideal for general light-load silent sliding scenarios.
POM: Boasts high hardness, ultra-low friction coefficient and superior dimensional stability, suitable for high-frequency continuous cyclic operation. Both materials effectively reduce operating noise and rail wear compared with traditional metal pulleys.
Application Scenarios
This custom 625ZZ Nylon And POM U-type pulley is widely used in precision automation equipment, linear guide systems, silent sliding machinery, packaging devices and customized compact mechanical equipment.
