625ZZ U Type Plastic Roller Pulley d5*D25*7mm
Custom 625ZZ Bearing PU U-Type Plastic Pulley | 5*25*7mm
The custom 625ZZ PU U-type plastic pulley is a miniature low-noise non-standard grooved pulley for precision linear guiding and light-load transmission systems. Adopting a dustproof double shielded 625ZZ bearing, this 5*25*7mm PU pulley achieves low-friction and smooth silent rotation, suitable for compact precision automation equipment.
Product Specifications
Model: Non-standard 625ZZ PU U-Type Pulley
Overall Dimension: 5× 25 × 7mm
Bearing Type: 625ZZ double metal shielded bearing
Outer Material: High-elastic wear-resistant PU plastic

Core Features
Premium PU outer cover features excellent noise reduction, shock absorption and wear resistance, effectively protecting guide rails against scratches and abrasion. Built-in 625ZZ shielded bearing ensures stable dustproof performance and long-term high-speed operation. Precision U-groove design avoids slipping and positional deviation. Custom 5*25*7mm non-standard size fits narrow and compact installation environments.
Material Advantages
Different from rigid metal pulleys, this PU plastic pulley is lightweight, silent and impact-resistant. It provides soft contact buffering, lowers friction loss and running noise, and supports long-duration cyclic operation with consistent stability.
Application Scenarios
This custom 625ZZ PU U-type pulley is widely applied in miniature silent automation machinery, precision linear guide systems, small packaging devices, instrument transmission mechanisms and customized compact mechanical equipment.
