In specialized high-speed automation, linear positioning, and automated pick-and-place packaging systems, an 8M Timing Belt with False Teeth (Mechanical Profile Cleat Attachment Systems) is the go-to solution for precise component indexing.

Unlike standard cleated belts where polyurethane profiles are permanently welded or vulcanized to the back of the belt, a False Tooth system uses a mechanical metallic insert embedded directly inside the belt’s tooth profile to bolt on custom fixtures.

Here is the technical breakdown of how this CNC-machined 8M false teeth system operates and why it is widely used in secondary packaging, automation, and glass/logistics lines.

1. Structural Engineering & Mechanism

The “False Tooth” concept relies on replacing a standard polyurethane tooth on an 8M pitch ($8\text{mm}$ from tooth-center to tooth-center) with a precision CNC-machined metal insert—typically made of stainless steel, brass, or aluminum.

• The Embedded Insert: The metallic insert is physically integrated into the timing belt’s polyurethane body during production or post-processing, perfectly matching the HTD 8M or STD 8M tooth geometry.
• The Threaded Interface: The metal inserts feature CNC-drilled, threaded blind holes (typically M3, M4, or M5 depending on the belt width). These threads emerge on the top (back) side of the belt, allowing engineers to bolt custom cleats, fixtures, or attachments directly to the belt.

A. Infinite Interchangability & Reusability

Welded profiles are permanent. If a product design changes, the entire belt must be discarded. With a CNC 8M false teeth system, you simply unbolt the current fixture and screw on a new one. This makes it highly economical for flexible production lines that handle shifting packaging sizes.

B. High Mechanical Strength & Precision

Polyurethane welds can shear off under high-load pushing applications or rapid indexing stops. False teeth mechanically distribute the pulling force through the metallic core of the belt, providing incredibly high mechanical torque resistance. CNC machining ensures the pitch tolerance stays perfectly uniform.

C. Zero Pulley Interference

Because the metal insert perfectly mirrors the 8M tooth profile, it meshes smoothly into standard 8M timing pulleys. It does not cause the belt to “jump pitch,” vibrate, or experience advanced wear when passing over the pulleys

At YONGHANG (Yonghang Transmission Belt Factory), we utilize advanced CNC milling centers to embed seamless, precision-threaded false teeth inserts into our premium polyurethane 8M belts. We can configure custom pitch spacing to perfectly match your automation index cycle.
