12A-G2 Rubber Top Chain 12A-G2 Rubber Top Roller Chain
The 12A-G2 rubber top chain is a widely used conveyor chain in various industrial fields. It is a special type of roller chain where each link is topped with a rubber coating, providing a non-slip surface and enhancing grip on conveyed materials. “12A” refers to the pitch of the rubber top chain, which is the distance between the centers of adjacent chain pins. In this example, the pitch is 12.7 mm (0.5 inches). “G2” refers to the strength grade of the rubber top chain; G2 has a higher strength grade than G1.
“Rubber top” refers to the rubber padding at the top of the links on the 12A-G2 rubber top chain. This helps reduce noise and vibration during operation and enhances the chain’s grip. This is particularly useful in applications such as conveyors, where the chain needs to grip and move products along surfaces. The 12A-G2 rubber top chain is commonly used in applications requiring non-slip surfaces, such as food processing, packaging, and filling industries. The rubber top also helps reduce noise and vibration during operation and extends the life of the chain and sprockets.

▍12A-G2 Rubber Top Chain Vs 12A-G1 Rubber Top Chain:
The main difference between the 12A-G2 and 12A-G1 rubber top chains lies in their strength rating. “G2” and “G1” represent the chain’s strength rating, with G2 having a higher strength rating than G1.
The higher strength rating of the 12A-G2 rubber top chain means it can withstand greater loads and wear more easily over time. Therefore, the 12A-G2 rubber top chain is a better choice for applications requiring higher loads or more demanding operating conditions.
Besides strength rating, these two rubber top chains may also differ in materials, dimensions, and finishes. When selecting a rubber top chain, carefully consider your specific application requirements and refer to the manufacturer’s specifications and recommendations to ensure you choose the best fit.
The rubber top of the 12A-G2 rubber top chain is thicker than that of the 12A-G1 rubber top chain. This makes the 12A-G2 chain more wear-resistant and better at suppressing noise and vibration. The 12A-G2 chain is also slightly heavier than the 12A-G1 chain.
The table below summarizes the main differences between the two chains:
| Feature | 12A-G2 Rubber Top Chain | 12A-G1 Rubber Top Chain |
|---|---|---|
| Rubber top thickness | 2.5mm | 2mm |
| Wear resistance | Better | Worse |
| Noise and vibration damping | Better | Worse |
| Weight | Heavier | Lighter |
| Price | More expensive | Less expensive |

▍12A-G2 Rubber Top Chain Sprockets and 12A-G2 Rubber Top Chain
The 12A-G2 rubber-top sprocket and the 12A-G2 rubber-top chain are two distinct components in a chain drive system, used together. The sprocket is responsible for the chain’s movement, while the chain transmits power from the motor to the load.
The 12A-G2 rubber-top sprocket is made of steel, and its rubber top helps reduce noise and vibration. This sprocket is specifically designed for the 12A-G2 rubber-top chain and is available in a variety of sizes and tooth counts. The 12A-G2 rubber-top chain is also made of steel, and its rubber top helps reduce wear. This chain is available in a variety of lengths and widths for various applications.
When choosing a 12A-G2 rubber top chain sprocket and a 12A-G2 rubber top chain, it is important to make sure that they are compatible with each other. The sprocket and chain should have the same pitch, width, and number of teeth. It is also important to make sure that the sprocket and chain are made of the same material.
Here are some of the benefits of using a 12A-G2 rubber top chain sprocket and 12A-G2 rubber top chain:
- Reduced noise and vibration
- Increased wear resistance
- Longer service life
- Improved efficiency
Here are some of the applications where 12A-G2 rubber top chain sprockets and 12A-G2 rubber top chains are commonly used:
- Conveyors
- Hoists
- Industrial machinery
- Food processing equipment
- Material handling equipment
If you are looking for a quiet, durable, and efficient chain drive system, then the 12A-G2 rubber top chain sprocket and 12A-G2 rubber top chain are good options.
