DA&DB Double-Sided Tooth Synchronous Belt: We offer two material options—rubber and PU. The rubber DA&DB Double-Sided Tooth Synchronous Belt utilizes premium imported Japanese synthetic neoprene rubber blended with multiple specialized rubber additives. The skeleton material consists of high-quality imported Japanese glass fiber cord. The tooth surface is protected by a high-elasticity nylon 66 fabric.
This product features the same pitch and tooth profile as single-sided tooth synchronous belts.
Primarily designed for dual-sided transmission, it offers synchronous operation, simultaneous power transfer, and dual efficiency. Ideal for applications requiring a single belt to drive opposing directions, compact installation spaces, or high-precision linkage between primary and auxiliary drives, this product is recognized and widely adopted across machinery, textiles, precision instrumentation, petrochemicals, and telecommunication cable industries for its lightweight construction, slip-free engagement, and low-noise operation.
DA&DB Double-Sided Toothed PU Synchronous Belt features symmetrical tooth profiles on both sides, enabling low noise and vibration during forward and reverse transmission. Complies with FDA and RoHS certifications.Steel wire or Kevlar core.Joint：Open/Endless with joint/Seamless (moulded)，Surface fabric and double-sided fabric or surface fabric, etc.
T20 double-sided tooth timing belts are used for drives with axles that rotate in opposite directions. The most common types are available in the double-toothed version, both in PU and neoprene. In addition, it is possible to make special double-toothed belts in PU. A standard toothed belt is coated with 90 ° Shore PU in which the desired tooth shape is milled. In this way it is even possible to create two different tooth shapes on one toothed belt. Ask our sales team for the possibilities.

Understanding the Structural Difference: DA Type vs. DB Type
Double-sided timing belts feature teeth on both the inside and outside surfaces, enabling a single continuous belt to drive multiple pulleys rotating in opposite directions. The tooth arrangement is categorized into two standard mechanical formats:
DA Type (Symmetrical / Directly Opposed Teeth): In a DA configuration, the teeth on the top and bottom surfaces are directly aligned with each other. This layout is designed for applications where exact angular synchronization between shafts on opposite sides of the belt is critical.
DB Type (Staggered / Alternating Teeth): In a DB configuration, the teeth on the top surface are offset or staggered relative to the teeth on the bottom surface. This alternating arrangement enhances overall belt flexibility, reduces bending stress over small pulley diameters, and minimizes operating noise during high-speed serpentine drives.
DA Type (Symmetrical / Directly Opposed Teeth): In a DA configuration, the teeth on the top and bottom surfaces are directly aligned with each other. This layout is designed for applications where exact angular synchronization between shafts on opposite sides of the belt is critical.
DB Type (Staggered / Alternating Teeth): In a DB configuration, the teeth on the top surface are offset or staggered relative to the teeth on the bottom surface. This alternating arrangement enhances overall belt flexibility, reduces bending stress over small pulley diameters, and minimizes operating noise during high-speed serpentine drives.
Material Options & Tensile Cord Construction
To suit varying operational temperatures, chemical exposures, and load demands, YONGHANG supplies dual-toothed belts in two continuous material formulations:
Neoprene Rubber Double-Sided Belts: Formulated with high-grade chloroprene rubber, continuous helically wound fiberglass tensile cords, and protective nylon canvas facing on both tooth sides. Excellent for high-speed flex endurance, heat resistance, and long service life.
Polyurethane (PU) Double-Sided Belts: Made from wear-resistant thermoplastic polyurethane (TPU) reinforced with high-tensile steel, stainless steel, or Kevlar (Aramid) cords. Ideal for cleanroom environments, zero-backlash indexing, and chemical/oil resistance.
Comprehensive Pitch ConfigurationsWe manufacture DA and DB double-sided belts across all major international pitch profiles:
Curvilinear Profiles: D-HTD 3M, D-HTD 5M, D-HTD 8M, D-HTD 14M, D-STD S5M, D-STD S8M.
Metric Profile Series: D-T5, D-T10, D-AT5, D-AT10.
Imperial Pitch Series: D-XL (0.200"), D-L (0.375"), D-H (0.500").
