UYANG PU Timing Belt with PAZ/PAR is an enhanced thermoplastic polyurethane synchronous belt featuring a durable fabric overlay on the tooth side (PAZ / NFT) and/or the back side (PAR / NFB). These fabric reinforcements are applied during manufacture to improve key performance characteristics beyond those of a standard PU timing belt.

Typical Use Cases
Precision motion control systems
High-speed automated machinery
Conveyor and accumulation applications
Packaging, printing, and material handling equipment
Drives with frequent start/stop or reverse cycles
Key Features
🔹 PAZ/NFT (Tooth Side Fabric)
Improved Wear Resistance: The polyamide (nylon) cloth on the tooth surface significantly reduces abrasion between belt teeth and pulley during repeated meshing, extending service life.
Lower Noise & Vibration: The fabric layer acts as a cushion between mating surfaces, reducing noise and vibration in high-speed or precision drives.
Cleaner Operation: PAZ cloth provides anti-dust and anti-oil properties, inhibiting contaminant adhesion on the tooth surface and supporting stable performance.
🔹 PAR /NFB (Back Side Fabric)
Reduced Friction & Thermal Load: A low-friction fabric on the belt’s backside lowers heat build-up under heavy load or high-speed operation, mitigating thermal aging of the PU material.
Enhanced Durability in Reverse/Bidirectional Motion: PAR backside reinforcement distributes stress more evenly under bidirectional drives or high tension, reducing wear and cracking.
Extended Belt Life: Reduced friction and mechanical stress contribute to longer operational life compared to uncoated belts.
🔹 Combined PAZ + PAR
Balanced Performance: Combining fabric on both the tooth side and back side yields quieter, smoother transmission with low friction.
Robust for Demanding Systems: Ideal for heavy-load, high-precision automation, packaging, printing, and conveying equipment where long life and reliability are required.
Lower Maintenance Cost: Extended durability reduces the frequency of belt replacement and associated downtime.
Typical Use Cases
Precision motion control systems
High-speed automated machinery
Conveyor and accumulation applications
Packaging, printing, and material handling equipment
Drives with frequent start/stop or reverse cycles
Technical Notes
PAZ/PAR coatings can be in green or black polyamide fabric depending on application requirements.
Fabric coverings are compatible with belts reinforced with steel, Kevlar, or stainless-steel cords and across common PU belt profiles.
| Type | Fabric Position | Key Characteristics | Typical Applications |
|---|---|---|---|
| Standard PU Timing Belt | None | Basic power transmission, cost-effective | General machinery, standard drives |
| PU Timing Belt with PAZ | Tooth side (PAZ / NFT) | Quieter operation, reduced tooth wear, precise meshing | Automation equipment, packaging machines |
| PU Timing Belt with PAR | Back side (PAR / NFB) | Low backside friction, improved durability against rollers and idlers | Conveyors, guide rollers, backside running systems |
| PU Timing Belt with PAZ + PAR | Tooth side + Back side | Low noise, low friction, extended service life | High-load systems, high-precision & advanced machinery |
PAZ is recommended when noise reduction, smooth meshing, and positioning accuracy are critical.
PAR is preferred when the belt runs against rollers or idlers on the backside.
PAZ + PAR offers the most balanced performance for long-life, high-duty, and high-value equipment.
