There are a number of options available in order to better suit your needs, so be sure to speak with a reputable shaft coupler manufacturer in order to ensure that you are getting a product that is best suited to your application needs and requirements. Many times these shaft couplers are utilized in applications where two different sized shafts must be joined together or when an application calls for a solid shaft to be joined with a flexible shaft.
There are a few different ways in which a shaft coupler can be attached. Occasionally, shaft couplers are welded into place, but in other applications bolting the coupler into place is effective enough. Often times a coupler will be used in an area or situation where it will need to be broken or break loose on impact, these shaft couplers are held in place through the use of shear pins.
These pins are specially designed to break off in order to permit the shafts to slide apart and out of the way. This can prove to be very useful and could potentially save lives in some applications such as in automobiles in the case of a car crash. Overall the most complicated part of a shaft coupler outside of the actual manufacturing process tends to be the installation of the shaft coupler.
Shaft couplers are nothing to take lightly as they allow for easy repair to any damaged shaft if they are installed correctly as well as properly maintained. A loose coupler could be a sign of a break in the shaft which should be addressed as soon as possible or can be a sign of a missing or damaged screw. In order to add top level safety to your application, contact a knowledgeable shaft coupler manufacturer and see if they can provide a solution for your need.
