Sponge Timing Belt
Sponge Timing Belt: Sponge and foam-backed timing belts that combine positive drive with a soft, high-grip conveying surface.
A Sponge Timing Belt pairs a toothed timing belt with a sponge or foam layer on the back. The toothed side drives the belt with accurate timing, while the soft sponge face grips and cushions the product. This makes sponge timing belts ideal for conveying, feeding and gently handling delicate items, and for applications where a firm but non-marking, high-friction surface is required. GOODLY produces sponge timing belts with open-cell foam, closed-cell sponge and cloth-reinforced sponge in a range of colours and thicknesses.

What Is a Sponge Timing Belt?
A Sponge Timing Belt is a timing belt with a sponge or foam layer bonded to the back. The toothed side drives the belt with accurate timing, while the soft sponge face grips and cushions the product. This makes sponge timing belts ideal for feeding, conveying and gently handling delicate items that must not be marked or damaged.
Because we manufacture in our own plant, we can advise on the right compound, cord and tooth profile for your machine before you order, and back it up with sample belts for your own testing.
Key Advantages of Our Sponge Timing Belt
Every belt is engineered, moulded and inspected in house, so the advantages below are backed by real production data rather than marketing language.
Soft, High-Grip Face
The sponge layer grips the product firmly yet gently, protecting delicate surfaces from marks and damage.
Accurate Timing Drive
The toothed side gives positive, slip-free transmission for synchronised feeding and positioning.
Absorbs Vibration
Foam backing cushions shocks and damps noise for smoother, quieter running.
Optional Cloth Layer
Blue or green cloth-reinforced sponge adds tear resistance and a low-friction surface.
Multiple Colours
Black, blue, orange, green and other sponge colours to suit your machine and product.
Made to Order
Thickness, width, length and profile manufactured to your drawing and sample.

Sponge Timing Belt Performance Data
The figures below are typical values from our own testing. Your exact application may need a different combination, so tell us the load, speed and environment and we will confirm.
| Surface | Soft, non-marking, high friction |
| Drive | Positive timing, minimal slip |
| Noise | Reduced by foam cushioning |
| Temperature | –10 °C to +80 °C (PU base), higher with silicone base |
| Thickness | 5 mm to 20 mm sponge |
| Edge | Square, rounded or profiled |
Sponge Timing Belt Materials and Reinforcement
We select the compound and the tension member together, because the material combination is what determines how a sponge timing belt performs over its working life.
Open-Cell Foam
Very soft and compressible, excellent for delicate, lightweight products.
Closed-Cell Sponge
Denser and more durable for general conveying and grip duties.
Cloth-Reinforced Sponge
Adds tear resistance and a smooth, low-friction surface for guided products.
Toothed Base Belt
PU, rubber or silicone timing belt selected for your drive and environment.
Industries That Use Our Sponge Timing Belt
From food and packaging to printing and automated assembly, the same engineering discipline is applied to every sponge timing belt we ship.

Sponge Timing Belt Frequently Asked Questions
Quick answers to the questions our customers ask most often about sponge timing belt.
What is a sponge timing belt used for?
It is used wherever a machine needs both accurate timing drive and a soft, high-grip contact surface, such as feeding, conveying and gently handling delicate products.
How thick can the sponge layer be?
We commonly supply 5 mm to 20 mm sponge, and custom thicknesses can be laminated on request.
What is the difference between foam and sponge?
Foam is usually open-cell and softer for very delicate items, while closed-cell sponge is denser and more durable for general conveying.
Can you add a cloth layer?
Yes, blue, green or black cloth-reinforced sponge can be added to improve tear resistance and provide a smoother surface.
Which base belt should I choose?
PU for the best precision, rubber for the strongest grip, and silicone when temperature or hygiene is the priority.
