This Optibelt MXL K 840 is a timing belt with an MXL profile and a length of 213.36 mm. It is used in low-power synchronous drives where teeth maintain position between the pulley and the belt.
You will find MXL-profile timing belts in small drives on equipment such as instruments, small pumps, and light positioning mechanisms. The teeth mesh with matching pulleys, so the belt keeps the driven part in step with the motor rather than relying on friction alone.
To confirm fit, read the marking on the back of the old belt and check the profile and length against this page. The profile must be MXL and the length 213.36 mm. Also inspect the pulleys for worn teeth, debris in the grooves, and correct alignment before installing the new belt.
If you are replacing a belt on a drive with more than one belt, inspect all of them and replace as a set where the drive is designed that way. Send the part number, the profile, and the length from the old belt when you request a quote.
