Silent Toothed Conveying Chains for Glass Industry
High-Performance Conveying Solution for Glass Manufacturing
Product Overview
The Silent Toothed Conveying Chain (also known as silent chain or toothed conveyor chain) is specifically engineered for the glass industry. It provides a smooth, quiet, and highly reliable conveying surface for handling glassware, bottles, and hot glass products throughout the production line – from glass forming machines to annealing lehrs and bottle conveyor systems.
Unlike conventional roller chains that generate vibration and noise, the silent toothed chain engages through precision tooth contact, delivering exceptional stability, minimal speed variation, and significantly reduced noise levels – a critical advantage for modern glass plants.
Designed to withstand high temperatures up to 500°C, these chains are manufactured from hardened steel alloys including Q235, manganese steel, alloy steel, and stainless steel 304/316. They feature a flat, non-slip conveying surface and are built for 24/7 continuous operation with minimal elongation and maintenance.
Key Features
| Feature | Benefit |
|---|---|
| Silent operation | Noise reduction compared to standard chains – ideal for noise-sensitive environments |
| High temperature resistance | Withstands up to 500°C – perfect for hot glass handling |
| Smooth, flat conveying surface | Prevents glass tipping, scratching, or misalignment |
| Anti-skid design | Secure product transport even at high speeds |
| High tensile strength | Resists stretching under continuous load |
| Wear-resistant construction | Long service life – 2–3 times longer than standard chains |
| Protective cap (countersunk thickened link) | Shields shaft ends, significantly extends chain life |
| Low vibration & speed variation | Superior stability compared to roller or hinge chains |

Applications in Glass Industry
Glass bottle forming machines (IS machines / row-type glass forming machines)
Glass machinery conveyor systems (bottle conveyors)
Hot glass gob handling (after shearing)
Annealing lehrs (inlet/outlet conveying)
Glassware production lines (cups, bowls, containers)
Tempering and heat treatment furnaces
Decal firing and thermal melting lines
Why Choose Silent Toothed Chains for Glass?
1. Noise Reduction
Glass plants are increasingly focused on worker comfort and environmental compliance. Our silent toothed chains reduce operating noise by up to 10–15 dB compared to standard roller chains.
2. Heat Resistance
Specially formulated materials and heat treatment allow continuous operation at 500°C without loss of tensile strength or dimensional stability.
3. No Product Damage
The flat, smooth, and non-slip surface ensures that hot glass bottles, jars, and delicate glassware remain stable – no tipping, scratching, or surface marks.
4. Low Maintenance
Hardened pins and pre-stressed link plates resist elongation. The protective cap design prevents shaft-end wear. Result: longer intervals between replacements and reduced downtime.
5. Customizable
We manufacture chains to your exact width, pitch, material, and pin configuration. Whether you need a 200 mm wide chain for bottle handling or a 500 mm wide chain for large glass sheets – we deliver.
Construction Highlights
Link plates – Shot-peened and pre-stressed for maximum fatigue resistance
Pins & bushings – Hardened alloy steel for wear resistance at high temperatures
Protective caps – Countersunk, thickened chain links protect shaft ends
Double-pin option – Recommended for higher load and longer service life (superior to single-pin chains)
Protective plate option – Available for enhanced product safety
