Idler sprockets
Idler Sprockets Factory
On a typical roller chain drive application, there is a drive sprocket and idler sprockets. Idler sprockets are designed in conveyor applications to essentially “carry” or guide a roller chain in a straight line, around a bend, or in a complete 360-degree directional change.
If an idler sprocket fails while in use, the result can be catastrophic depending on the application. Because of this, it is always important to monitor the status of your idler sprockets and use a high-quality product from a trusted factory.
Idler Sprocket Construction
- Teeth – The teeth on our idler sprockets come standardly hardened from 30-teeth and under to ensure elongated durability.
- Sprocket Body – Our materials used in our idler sprocket bodies: premium 1018 & 1045 carbon steel, 304 or 316 stainless steel, and UHMW or Nylon plastics.
- Idling Component – This component is typically a ball bearing, needle bearing, bronze, or non-metallic plastic.
Idler Sprocket Types
When using an idler sprocket, you want the least amount of friction with your setup. It is imperative to utilize high-quality components such as bearings, plastics, or bronze to eliminate as much friction as possible, making your setup more effective and energy-efficient.
An example of our dedication to maintaining high quality: on our ball bearing configuration (the most common type), we utilize sophisticated deep-groove ball bearings that meet or exceed ABEC 3 tolerances, use grade-10 balls, and feature motor bearing-rated Polyrex EM grease. Regardless of which configuration you use, we provide the best performing idler sprocket on the market.
Ball Bearing Idler
The most standard configuration using a precision ball bearing pressed and secured into the sprocket plate. These are economical and can withstand harsh and heavy-duty application requirements.
Needle Bearing Idler
Able to withstand higher capacities because there is more surface contact between the rotating parts. Surprisingly, this design also creates less friction and is more stable when mounted onto the shaft.
Bronze Bearing Idler
Probably the second most common configuration today. This is due to the versatility of bronze and its economical price tag. Additionally, it has no moving parts, so in some applications, it can last longer.
Bronze Bushed Idler
Bronze bushed idler sprockets provide similar heavy-duty performance and are essentially identical in application to bronze bearing idler sprockets.
Non-Metallic Idler
Manufactured using plastic and stainless-steel components so they can operate in extremely corrosive and food-grade environments. Most of these are non-stock items but can be custom-made with short lead times.
