Product Specifications
Model: 625RS V-Type Plastic Pulley
Overall Dimension: 5 × 21.7× 14mm
Bearing Type: 625RS rubber sealed bearing
Optional Material: Nylon, POM (Acetal)
Structure: Embedded sealed bearing + precision V-type groove plastic body
Core Features
Made of high-quality Nylon and POM materials, this 625RS V-type pulley offers superior wear resistance and anti-aging stability. The fully sealed bearing effectively blocks dust and moisture for long-term low-noise high-frequency operation. Standard precision V-groove perfectly fits belt and rail guidance, effectively preventing deviation and slipping. Compact non-standard size adapts to various custom precision mechanical installations.
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 long-term high-frequency cyclic operation. Both plastic materials greatly reduce running noise and mechanical wear compared with metal pulleys.
Application Scenarios
This 625RS V-type plastic pulley is widely used in precision automation equipment, linear guide systems, belt transmission mechanisms, packaging machinery and customized compact mechanical devices.
