As an established drive manufacturer certified with ISO 9001:2015 and ISO 14001:2015, Kaihong leverages decades of rubber compounding expertise and specialized molding facilities. Our t-type timing belts deliver strict pitch uniformity, dependable fatigue resistance, and clean zero-grease operation for packaging equipment, textile machinery, and automated conveying systems worldwide.
The classic metric T-profile features a standardized 40° trapezoidal tooth angle. Power is transmitted directly through positive physical meshing between the belt teeth and matching pulley grooves, yielding crucial drive performance characteristics:
Unlike V-belts or flat belts that rely purely on friction and suffer from speed drift, the trapezoidal tooth mesh locks drive speed in exact proportion. This positive engagement guarantees zero rotational slip and high repeat accuracy during fixed-length indexing and feeding cycles.
While metal gear trains transmit motor vibration directly into machine frames, the synthetic elastomer body absorbs torsional shocks and mechanical impacts, protecting connected shaft bearings and reducing overall operational noise.
Because power is transmitted via tooth meshing rather than high frictional wedge tension, required installation pretension is significantly lower. This reduced radial tension minimizes shaft deflection and extends the service life of motor bearings.
Kaihong T-series belts integrate high-modulus materials formulated for environmental resilience, wear resistance, and long-term pitch stability.
| Layer | Material | Core Function |
| Tensile Member (Cord) | Helically Wound Fiberglass Cord | Positioned along the neutral pitch line; carries tensile load with near-zero stretch to maintain pitch pitch accuracy |
| Belt Body / Elastomer | Chloroprene Rubber (CR) Compound | Encapsulates tensile cords; provides dynamic elasticity, oil resistance, and damping for smooth meshing |
| Tooth Facing Layer | Nylon 66 High-Elasticity Fabric | Covers tooth surfaces; lowers friction coefficient, resists flank wear, and extends operational lifespan |
Operating without grease, oil baths, or metal-to-metal contact, this dry drive system eliminates oil mist and fluid splatter. This makes it ideal for food processing, pharmaceutical handling, paper production, and textile manufacturing where product cleanliness is mandatory.
Kaihong produces T-profile synchronous belts across standard imperial/metric pitch designations to fit global equipment specifications:
| Item | T2.5 | T5 | T10 | T20 |
| Pitch (mm) | 2.5 | 5.0 | 10.0 | 20.0 |
| Tooth Height (mm) | 0.7 | 1.2 | 2.5 | 5.0 |
| Belt Thickness (mm) | 1.3 | 2.2 | 4.5 | 8.0 |
| Tooth Angle | 40° | |||
Thanks to its precise synchronization, low maintenance needs, and quiet running characteristics, an industrial t-type timing belt is widely integrated across manufacturing machinery:
Following proper handling practices during mounting and maintenance preserves internal tensile cords and prevents premature tracking wear.
Always decrease shaft center distance or loosen tensioners prior to fitting new belts. Never force, lever, or pry belts over sheave lips using screwdrivers or crowbars. Prying snaps internal fiberglass cords, creating invisible internal fractures that trigger sudden belt breakage under normal operating load.
Ensure drive and driven shafts are aligned perfectly parallel, and verify that pulley grooves line up precisely. Angular or parallel shaft misalignment causes belt tracking drift, uneven edge wear, and elevated noise.
Apply initial tension according to machinery manual specs using a deflection gauge or sonic meter. Under-tensioning leads to tooth climbing or jumping under peak torque, while over-tensioning accelerates tooth wear and overloads motor bearings.
Store spare belts in a cool, dry room away from direct sunlight, oil, and ozone-generating electrical equipment. Store belts lying flat or hanging on wide radii; never fold, kink, or sharply bend fiberglass-reinforced belts during handling.
A t-type timing belt relies on positive tooth engagement rather than sidewall friction wedging. This provides a constant, 100% slip-free speed ratio, requires significantly lower installation tension (reducing bearing load), eliminates periodic tension adjustments due to stretch, and operates completely without lubrication.
No. Although they may share identical pitch distances (for example, T10, AT10, and HTD 10M are all 10 mm pitch), their underlying tooth angles, tooth depths, and root radii differ fundamentally. Running a T-series belt on AT or HTD pulleys causes severe tooth binding, dynamic noise, and rapid tooth shear failure. Always match T-profile belts with T-profile pulleys.
Kaihong offers extensive custom manufacturing capabilities, including slitting to non-standard millimeter widths, custom pitch lengths, thickened or grooved backings, surface perforations, integrated guide cleats, food-grade polyurethane (PU) formulations, antistatic conductive compounds, and high-temperature elastomeric formulations built to customer drawings or physical samples.
