PU Round Belt Product Description
Product Overview
PU round belts (polyurethane round belts) are industrial transmission belts with a circular cross-section, featuring high-performance polyurethane as the core material. Combining elasticity, wear resistance, and easy processability, they serve as a typical representative of friction-type transmission belts. By fitting tightly with pulley grooves, they transmit power and are widely used in light machinery, automation equipment, and material conveying scenarios, making them an ideal choice to replace traditional rubber round belts for efficient transmission.
Core Features
Material Advantages: Made of high-purity polyurethane raw materials, they have extremely high tensile and pulling strength, with wear resistance 2-3 times that of ordinary rubber belts; they are oil-resistant, waterproof, and chemical corrosion-resistant, free of plasticizers, not prone to elongation or deformation during long-term use, and operate within a temperature range of -35℃ to 80℃.
Structural Design: With a circular cross-section, they come in two types: smooth surface (orange, high surface finish) and rough surface (green, uniform rough particles). The rough-surfaced version has stronger friction to effectively prevent slipping; they support free splicing and can be quickly joined into rings, triangles, or any shape via hot melting, meeting non-standard equipment requirements.
Performance: With a transmission efficiency of up to 0.98, they run smoothly and quietly, automatically slipping under overload to protect equipment; their elastic buffering characteristics relieve load impact, have low installation accuracy requirements, and are easy to maintain.

Installation & Maintenance
Installation Steps: Measure required length → Cut belt → Hot melt splicing (control temperature to avoid burning) → Trim joint → Install into pulley groove.
Maintenance Tips: Regularly clean surface oil and dust, avoid contact with high-temperature flammable environments; check belt wear after overload slipping, adjust center distance and re-tension if necessary.
Selection Guide
Load Matching: Choose smooth small-diameter models (Φ2-Φ5mm) for light-load high-speed scenarios, and rough large-diameter models (Φ6-Φ15mm) for heavy-load anti-slip needs.
Environment Adaptation: Choose oil-resistant formula models for oily environments, anti-static/food-grade models for clean workshops, and high-temperature resistant materials (-20℃ to 80℃) for high-temperature conditions.
Customization Services: Support processing based on drawings/samples, can add steel wire/cores to enhance tensile strength, meeting special requirements of non-standard equipment.
