Product Specifications
Model: 624RS V-Type Plastic Pulley
Overall Dimension: 4× 20× 12mm
Bearing Type: 624RS rubber sealed bearing
Optional Material: Nylon, POM (Acetal)
Structure: Embedded sealed bearing + precision V-type groove plastic body
Core Features
Made of premium Nylon and POM materials, this 624RS V-type pulley features excellent wear resistance and anti-aging durability. The fully sealed bearing prevents dust and moisture intrusion, supporting stable long-term low-noise high-frequency operation. Precision V-groove design effectively avoids belt deviation and slipping, ensuring accurate and consistent transmission. Compact 4*20*12mm size fits various miniature precision automation and custom mechanical assemblies.
Material Advantages
Nylon: Lightweight, high toughness and cost-effective, ideal for general light-load silent transmission scenarios.
POM: High hardness, ultra-low friction and stable dimensional accuracy, suitable for continuous high-frequency cyclic operation. Both materials greatly reduce running noise and mechanical wear compared with metal pulleys.
Application Scenarios
This 624RS V-type plastic pulley is widely applied in miniature automation equipment, linear sliding guide systems, belt transmission mechanisms, precision packaging machinery and customized compact mechanical devices.
