Product Specifications
Model: Non-standard 696ZZ U-Type Plastic Pulley
Overall Dimension: 6 × 21× 8mm
Bearing Type: 696ZZ double metal shielded bearing
Optional Material: Nylon, POM (Acetal)
Structure: Integrated steel bearing + plastic U-groove body
Core Features
This 696ZZ plastic pulley adopts high-quality nylon or POM material, featuring high hardness, excellent wear resistance and anti-aging performance. The embedded 696ZZ dustproof bearing ensures low-friction stable rotation and long service life. Precision U-groove design effectively prevents slipping and running deviation. Non-standard 6*21*8mm size perfectly fits narrow and customized installation spaces.
Material Advantages
Nylon: Lightweight, good toughness, impact-resistant and cost-effective, suitable for general light-load silent operation.
POM: High rigidity, low friction coefficient, superior dimensional stability and abrasion resistance, ideal for high-frequency continuous operation. Both materials replace traditional metal pulleys to reduce noise and equipment wear.
Application Scenarios
This custom 696ZZ nylon/POM U-type pulley is widely used in miniature silent automation machinery, precision linear guide systems, door and window sliding devices, small packaging equipment and customized compact mechanical systems.
