Product Specifications
Model: Non-standard 627ZZ U-Type Plastic Pulley
Overall Dimension: 7× 39 × 8mm
Bearing Type: 627ZZ double metal shielded bearing
Optional Material: Nylon, POM (Acetal)
Structure: Embedded steel bearing + precision U-groove plastic body
Core Features
Constructed with high-quality Nylon and POM materials, this 627ZZ plastic pulley delivers excellent wear resistance, structural stability and anti-aging performance. The built-in dustproof 627ZZ bearing ensures smooth, low-noise and long-term high-speed operation. Precision U-groove design prevents slipping and running deviation. Non-standard 7*39*8mm size fits special and narrow installation spaces.
Material Advantages
Nylon: Lightweight, high toughness and impact-resistant, offering cost-effective performance for regular light-load silent operation.
POM: Features high hardness, ultra-low friction and great dimensional stability, perfect for high-frequency continuous cycling work. Both materials effectively reduce operating noise and rail abrasion compared with traditional metal pulleys.
Application Scenarios
This custom 627ZZ Nylon And POM U-type pulley is widely used in silent automation equipment, precision linear guide systems, sliding machinery, small packaging devices and customized compact precision mechanical systems.
