Chain pins

Listing ID #3615733

When the chain engages with the sprocket or runs on a curved rail section, the chain flexes causing the chain to stretch. In most cases, this is due to wear of the bearing parts such as the pins and bushings. As chain pitch elongation increases, the chain tends to climb the top of sprocket. This makes smooth operation of the conveyor impossible. The limit of pitch elongation is generally 2% - 6 % of the chain pitch.
