2 Appropriate selection of number of teeth (speed ratio), center-to-center distance, and arrangement of SPROCKETS is crucial for service life of a ROLLER CHAIN and a sprocket . Pay due consideration to the selection of SPROCKETS to avoid decreasing smooth rotation and transmission efficiency. Finished SPROCKETS FBN (finished for new JIS key) and FB (finished for old JIS key) SPROCKETS are a version, finished with shaft bore, key groove, and set screw, of KCM standard sprocket B-type. Centralized production system is employed to ensure high precision and stable quality of products which are manufactured in the excellent facilities under stringent quality control.
