Long Synchronous / STS Belts (LSB-U) are high-precision open-end and endless polyurethane timing belts designed for clean, dust-free synchronous power transmission and conveyance. Built with durable polyurethane teeth and backing reinforced with high-tensile steel or aramid cords, these long-span belts eliminate debris and contamination, making them ideal for food processing machinery, cleanrooms, and accurate reciprocating motion in indexing applications.
 
Available Models:
Bancollan Long STS Profiles: S2M, S3M, S5M, S8M
Bancollan Long Synchronous Profiles: XL, L, H, T5, T10
 
Configurations & Surface Coating Options:
Endless (Long-span continuous jointless belts)
Open-End (Continuous roll lengths)
Coating / Backing Surface Options:
Standard (No Coating): Plain polyurethane backing for standard indexing and precision drives.
Bottom / Tooth Side Fabric (PAZ / Nylon Fabric): Low-friction nylon coating on the tooth surface to reduce noise, friction, and wear during pulley engagement.
Top / Back Side Fabric (PAR / Nylon Coating): Nylon coating on the back surface for smooth sliding, reduced friction, and accumulation conveyance.
Double-Sided Fabric (PAZ/PAR): Nylon fabric coating on both the tooth profile and back surface for combined low-friction performance.
