Product Specifications
Model: Non-standard 696ZZ H-Type Plastic Pulley
Overall Dimension: 6× 21 × 8mm
Bearing Type: 696ZZ double metal shielded bearing
Optional Material: Nylon, POM (Acetal)
Structure: Embedded steel bearing + precision H-type limit groove
Core Features
This non-standard 696ZZ H-type pulley adopts high-performance Nylon and POM raw materials, offering excellent wear resistance and anti-aging durability. The precision dustproof bearing ensures stable long-term high-frequency operation without noise. Standard H groove effectively prevents track deviation, slipping and surface abrasion. Slim 8mm thickness and compact 6*21*8mm size suits narrow installation spaces and custom mechanical designs.
Material Advantages
Nylon: Lightweight, tough and cost-efficient, suitable for general light-load silent sliding applications.
POM: High rigidity, ultra-low friction and precise dimensional stability, excellent for continuous cyclic operation. Both plastic materials greatly reduce noise and wear compared with traditional metal pulleys.
Application Scenarios
This 696ZZ Nylon And POM H-type pulley is widely used in precision automation equipment, linear sliding systems, track transmission structures, intelligent devices and customized compact machinery.
