695zz H Type Plastic Roller Pulley d5*D19.5*8mm

Custom 625ZZ Nylon And POM H-Type Plastic Pulley | 5*19.5*8mm

The custom 625ZZ H-type plastic pulley is a non-standard limit track pulley available in Nylon and POM. Equipped with double shielded dustproof 625ZZ steel bearing, this 5*19.5*8mm H-groove pulley offers low-friction, stable and quiet rolling for light-duty linear guide and transmission systems.

Product Specifications

Model: Non-standard 625ZZ H-Type Plastic Pulley

Overall Dimension: 5× 19.5× 8mm

Bearing Type: 625ZZ double metal shielded bearing

Optional Material: Nylon, POM (Acetal)

Structure: Embedded steel bearing + precision H-type limit groove

Core Features

Made of high-quality Nylon and POM materials, this 625ZZ H-type pulley features reliable wear resistance and anti-aging stability. The built-in dustproof bearing supports long-term low-noise and high-frequency operation. Precision H-type limit groove avoids track deviation, slipping and surface abrasion. Compact non-standard 5*19.5*8mm size matches custom miniature mechanical and linear sliding installations.

Material Advantages

Nylon: Lightweight, high toughness and cost-effective, ideal for general light-load silent sliding scenarios.

POM: High hardness, ultra-low friction and stable dimensional accuracy, suitable for long-term cyclic operation. Both plastic materials greatly reduce running noise and mechanical wear compared with traditional metal pulleys.

Application Scenarios

This 625ZZ Nylon And POM H-type pulley is widely applied in precision automation equipment, miniature linear sliding systems, track transmission mechanisms, smart devices and compact customized machinery.
