Processed with axis holes, key grooves, and screw holes!
When using the gear, it is necessary to perform additional processing of the shaft hole, such as hole machining, keyway machining, and tapping, to match the mounting shaft. We have prepared the "FBN/FBP" series of gear shaft hole finished products, which have been pre-processed with holes, keyways, and tapping for the B-type spur gear. No additional processing of the shaft hole is required, and you can use it immediately after delivery.
