Clamp Collar

What is a clamp collar? Cheap Insurance. I am one of those cautious types and discovered these late one night on the McMaster-Carr web site.

I place it right behind the rotor and tighten it into place. I have been using them now for just about 9 years and consider them a very, very reasonably priced fail safe or insurance policy on the set screws I just discussed.

Interestingly enough I have been talking with PYI about clamp collars for a while now, and using them for about 9 years. PSS will be soon launching their own version of this. They claim they will be making their own product in-house as they feel they can control the quality better. According to an inside source they are reported to hold over 1000 pounds of force on a 1" shaft. That, is very good insurance.

Until PYI launches their own version: Clamp Collar
