Name: STD Timing Belts (S2M to S14M) | Custom & Standard Sizes - Hansheng
Brand: Hansheng Automation
SKU: 270224625

Hansheng Automation (Dongguan) Co., Ltd. is one of the most experienced manufacturers and suppliers of std timing belt in China. If you're going to wholesale bulk cost-effective std timing belt made in China, welcome to get pricelist and quotation from our factory. Also, customized service and OEM&ODM service are available.

Hansheng Automation's STD timing belts are available in standardized sizes (such as the full range from S2M to S14M) or customized sizes based on the packaging machinery's transmission torque and installation space requirements, ensuring precise engagement with components such as conveyor rollers and slitting shafts. Leveraging its expertise in precision manufacturing-from ISO/DIN/GB Grade 5 gear machining (suitable for synchronous pulley transmissions), ±0.002mm ultra-mirror CNC machining (guaranteed for transmission component accuracy), to customized casting capabilities (supporting the transmission structures of large-scale packaging equipment)-Hansheng Automation can also provide supporting components that operate in conjunction with timing belts.

Why Choose STD Profile Belts?

High Torque Capacity

Transmits up to 1.5 - 2 times more power than standard trapezoidal timing belts (like XL, L, H series).

Anti-Jumping (No Slippage)

The deep tooth engagement prevents tooth jumping (ratcheting) during sudden starts or stops.

Ultra-Low Noise

The involute engagement reduces the "polygon effect" and air compression noise, making it ideal for quiet environments.

Tooth Profile & Dimensions

Belt Type	Pitch (p)	Tooth Height (ht)	Belt Thickness (hs)
S2M	2.0 mm	0.76 mm	1.36 mm
S3M	3.0 mm	1.14 mm	1.90 mm
S4.5M	4.5 mm	1.71 mm	2.81 mm
S5M	5.0 mm	1.91 mm	3.40 mm
S8M	8.0 mm	3.05 mm	5.30 mm
S14M	14.0 mm	5.30 mm	10.20 mm

Material & Construction

Our STD timing belts are engineered with a 3-layer structural design to ensure zero-maintenance operation:

Tension Cord (Fiberglass / Kevlar)

High tensile strength glass-fibre cords prevent elongation and belt stretch under high-load conditions.

Belt Body (Neoprene / PU)

Made from high-quality Chloroprene rubber (CR) or Polyurethane (PU), offering excellent resistance to oil, heat, and flex fatigue. Operating temperature ranges from -20°C to +100°C.

Tooth Facing (Nylon Fabric)

A tough, wear-resistant nylon cover protects the tooth surfaces, reducing friction and extending the belt's lifespan.

Standard Widths Guide

We offer custom cutting services for sleeve widths. Below are the standard width options for different STD pitches:

S2M / S3M: 6mm, 9mm, 15mm
S5M: 9mm, 15mm, 25mm
S8M: 15mm, 20mm, 25mm, 30mm, 40mm
S14M: 40mm, 50mm, 85mm, 115mm

(Note: Custom widths and open-end STD belts are also available upon request.)
