- Model: For ANSI #40 / DIN(ISO)08A Chain. Size: 12mm Bore Idler Tensioner Sprocket 14 Tooth, 12.7mm (1/2") Pitch, 64mm Outside Diameter.
- Idler sprocket is a flat sprocket, with 2 precision bearings (6201Z) that allows the sprocket to rotate freely. Idler sprockets are normally mounted in a fixed position on a fixed shaft.

Best Mechanical Roller Chain Sprockets Buying Guide
Before choosing the best mechanical roller chain sprockets you should consider following options:
1. Roller materials: The first thing to consider when looking at roller materials is the space they are going to be used in. The environment they are going to be used in will affect the type of material used.
If they are going to be used in a corrosive environment, then you may need to choose a material that is resistant to corrosion.
If they are going to be used in a hot environment, then you may need to choose a material that has a higher resistance to heat.
Other factors that will affect the type of materials you need to choose from are their application and wear resistance requirements.
2. Roller dimensions: Before you purchase your mechanical roller chain sprockets, you will need to know what size you require.
This will depend on the application they are going to be used in. They could be a specific size or range of sizes.
If you are unsure about the size you require, then you can always contact our team at Chain Drive Australia for further assistance.
3. Drive ratio: If you are looking for a specific drive ratio, then you need to ensure that you purchase the correct chain sprockets for the job.
It is important to note that the chain size will affect the drive ratio that the chain sprockets will have.
If you have a specific drive ratio in mind, then you need to make sure that the chain sprockets you purchase have the correct ratio.
If you are unsure of what drive ratio you require, then you can always contact our team at Chain Drive Australia for further assistance.
4. Other requirements: Before you purchase your chain sprockets, you will need to consider any other requirements that need to be met.
This will include things such as the noise level they produce, the speed at which they operate, the torque and horsepower output, and the efficiency they have.
If you are looking for chain sprockets that will operate in a specific environment, then you will need to ensure that the ones you purchase meet the requirements for that environment.
We can provide you with chain sprockets that will suit your application, so contact us for further assistance.
5. Maintenance: The maintenance that is required for chain sprockets will depend on the type of materials they are made from, how they are going to be used, and any other requirements that need to be met.
If you are looking for chain sprockets that require minimal maintenance, then you may need to consider purchasing chain sprockets that are made with synthetic materials.
It is important to note that synthetic materials are more prone to wear, and will require more frequent replacement.
If you are looking for chain sprockets that don’t require much maintenance, then you may need to consider purchasing chain sprockets that are made with steel materials.
Steel materials are not as prone to wear, and will not require as much maintenance as synthetic materials.
6. Cost: The cost of chain sprockets will depend on many factors. The materials they are made from, the drive ratio they have, and any other requirements that need to be met will all affect the price.
It is important to note that chain sprockets that are made with synthetic materials will usually be more expensive than chain sprockets that are made with steel materials.
