Product Specifications

Model: Non-standard 696ZZ U-Type Plastic Pulley

Overall Dimension: 6 × 25.5× 8.5mm

Bearing Type: 696ZZ double metal shielded bearing

Optional Material: Nylon, POM (Acetal)

Structure: Embedded steel bearing + precision U-groove plastic body

Core Features

Made of high-quality Nylon and POM materials, this 696ZZ plastic pulley offers excellent wear resistance, anti-aging performance and stable structural rigidity. The built-in dustproof bearing ensures long-term low-noise and stable high-speed operation. Precision U-groove design effectively prevents slipping and running deviation. Custom non-standard 6*25.5*8.5mm size fits special and narrow installation spaces.

Material Advantages

Nylon: Lightweight, high toughness and impact-resistant with great cost performance, suitable for general light-load silent sliding applications.

POM: Features high hardness, ultra-low friction coefficient and reliable dimensional stability, ideal for high-frequency continuous cyclic operation. Both materials effectively reduce operating noise and guide rail wear compared with traditional metal pulleys.

Application Scenarios

This custom 696ZZ Nylon and POM U-type pulley is widely used in miniature automation machinery, precision linear guide systems, silent sliding equipment, small packaging devices and customized compact mechanical systems.
