Would anyone know where I could get a new one of these (bearing clamp) for a 24" Von Weise Actuator? See attached pictures. I called Von Weise and they told me they to not sell individual parts. They suggested that I buy a whole new actuator for $235.00 .... DUH! If I can't find a replacement, then I'll just have to clean up the one I have, grease it, and install it. Thank you in advance for your help! The I.D of the bracket is 1 3/4".
