Product Overview of Sprockets
Application of Sprockets: It is widely used in mechanical transmission in chemical industry, textile machinery, food processing, instrumentation,and petroleum
■ Only Sprockets and chains of the same specifications can be used in combination.
This series is ISO 12B Sprockets, and can be used in combination with MISUMI 40B series chain.
■ Do not use it with ISO/ANSI 12A series chain, which may cause the chain Sprockets mechanism to fail to function properly!
■ Due to process reasons, it is impossible to guarantee the coincidence of the tooth tops of multiple Sprockets. If you need to use the tooth tops in an overlapping manner, please contact us.
Actual Product
Product Feature of Sprockets
1. Sprockets, Multi-tooth load-bearing, safe and reliable;
2. Sprockets, Flexible transmission, absorbing shock and vibration;
3. Sprockets, Large center distance range, low manufacturing and installation accuracy requirements;
4. Sprockets, Compared with belt transmission, the transmission ratio is more accurate and the transmission efficiency is higher. It is suitable for the harsh environment of high temperature, dust and humidity.
■ Sprockets, chain selection
Misumi’s Sprockets and chain product selection supports the principle of “Nominal Numbering”

Usage Method of Sprockets
Example Use of Sprockets
Precautions of Sprockets
1. Sprockets tightness should be suitable. If it is too tight, it will increase power consumption, and bearing is easy to wear; if it is too loose, the Sprockets is easy to runout and fall off the chain.
The degree of tightness of the Sprockets is: if lifted up or pressed down from the middle of the Sprockets, the center distance between the two Sprockets is about 2%-3%.
2. The Sprockets shall be installed on shaft without swing and skew.
The end faces of the two Sprockets in the same transmission assembly should be in the same plane. When the center distance of the Sprockets is less than 0.5 meters, the deviation can be 1 mm.
When the center distance of the Sprockets is more than 0.5 meters, the deviation can be 2 mm. But there shall be no friction on Sprockets tooth side. Integral offset.
If the offset is too large, chain is prone to fall off and wear is likely to accelerate. When replacing the Sprockets, you must pay attention to check and adjust the offset
3. After the Sprockets is severely worn, the new Sprockets and the new chain should be replaced at the same time to ensure good meshing.
You cannot replace new Sprockets separately. Otherwise, it will cause bad engagement and accelerate the wear of new Sprockets.
If the tooth surface of the Sprockets is worn to a certain degree, it should be turned over in time (the Sprockets used with adjustable surface) to extend the life time.
4. If the new Sprockets is too long or elongated after use, and difficult to adjust, the links can be removed by the case, but the number of the links must be even.
The link should pass through the back of the Sprockets with the lock piece being inserted outside, and the opening of the lock piece should be in the opposite direction of the turning.
5. Lubricating oil should be timely filled when Sprockets are working. Lubricating oil must enter the matching clearance between the roller and the inner sleeve to improve working conditions and reduce wear.
6. The old Sprockets cannot be mixed with some of the new Sprockets, and should be replaced as a complete set, otherwise it is easy to produce impact in the transmission. Separate replacement of Sprockets will increase wear.

Frequently asked question (FAQ)
- Question: I bought MISUMI chains, but why can't I use them on my original sprocket?
- Answer: Please confirm the specifications of the original sprocket and chain. Specification series number may not match. In addition, there are two specifications: A series and B series in China. The two specifications of sprocket chain are not universal.
- Question: Does the sprocket need routine maintenance after installation and use?
- Answer: The chain needs regular maintenance after installation and use. These include daily lubricant application, confirmation of chain slack. After the sprocket is severely worn, the new sprocket and the new chain should be replaced at the same time to ensure good meshing.
- Question: I need to use two overlapped sprockets, I want the tooth top direction to be consistent, is it possible?
- Answer: Due to process reasons, it is impossible to guarantee the overlapping of the tooth tops of several sprockets. If the tooth tops are required to be overlapped, please contact our company or indicate on the order (the tooth tops need to be overlapped)
- Question: The engraving on the sprocket does not match the packaged model, is it shipped wrongly?
- Answer: The product model is subject to the label on the shipping bag and the actual size. The engraving is only the factory management number of the sprocket product during processing, and is not directly associated with the product model.
