Answer: This is largely application specific. One-piece collars a good starting point for most applications. They are best suited for applications where you have shaft end access and/or where you want to install the collar and never move it again. They do have some advantages over the two-piece types like they take less time to install because they only have one screw. They are also more cost effective because they take less time to manufacture. The two-piece collars do have some advantages in certain applications like when you want to remove the collar at some point and install it again without shaft end access. They also have a balanced design as a standard option which is good for applications that have high RPMs. In this case the customer was just using the collar to align a sprocket on a shaft so the one-piece was perfect since they would never need to move it.
