▍12B-G1 Rubber Top Chain Advantages:
The 12B-G1 rubber top chain is a type of roller chain that has a rubber top on the chain links. This rubber top provides a number of advantages over a standard roller chain, including:
1. Non-marking: The rubber top helps to protect sensitive materials from being damaged by the chain. This makes it ideal for applications where a non-marking 12B-G1 rubber top chain is required, such as conveying finished wood products, glass, or synthetic panels.
2. Durability: The rubber top helps to protect the chain from wear and tear. This makes it a more durable 12B-G1 rubber top chain than a standard roller chain.
3. High strength: The rubber top does not significantly reduce the strength of the chain. This means that the 12B-G1 rubber top chain can still be used in applications where high strength is required.
4. Quiet operation: The rubber top helps to reduce noise and vibration, making it a quieter 12B-G1 rubber top chain than a standard roller chain.
5. Low maintenance: The rubber top helps to protect the 12B-G1 rubber top chain from wear and tear, which means that the chain requires less maintenance than a standard roller chain.
In addition to these advantages, the 12B-G1 rubber top chain is also available in a variety of materials, including natural rubber, nitrile rubber, and neoprene rubber. The choice of material will depend on the specific application.

▍12B-G1 Rubber Top Chain Lubrication and Maintainance
12B-G1 rubber top chain is a high-quality chain that is designed to be durable and long-lasting. However, like any chain, it requires proper lubrication and maintenance in order to function properly and last for many years.
Here are some tips for lubricating and maintaining a 12B-G1 rubber top chain:
- Lubricate the chain regularly. The frequency of lubrication will depend on the operating conditions, but it is generally recommended to lubricate the rubber top chain every 250-500 hours of operation.
- Use the correct type of lubricant. The type of lubricant that you use will depend on the operating conditions, but it is generally recommended to use a high-quality, synthetic lubricant.
- Apply the lubricant evenly. The lubricant should be applied evenly to all of the links in the rubber top chain.
- Remove any excess lubricant. Excess lubricant can attract dirt and debris, which can shorten the life of the rubber top chain.
- Inspect the chain regularly. Inspect the rubber top chain for wear and tear, and replace any damaged links as soon as possible.
By following these tips, you can help to ensure that your 12B-G1 rubber top chain will last for many years.
Here are some additional tips for maintaining a 12B-G1 rubber top chain:
- Clean the chain regularly. This will help to remove dirt and debris that can build up and cause wear.
- Inspect the sprockets for wear. Worn sprockets can cause premature wear on the rubber top chain.
- Keep the chain properly aligned. A misaligned rubber top chain can cause excessive wear and tear.
- Store the chain properly. When the rubber top chain is not in use, it should be stored in a clean, dry place.
