This kit works on VAC-100,Vac-60, VAC-1000 and VAC-600 or anywhere it is needed to repair 42mm bearing support. This resolves a common issue on some machines where the shaft can no longer support the roller for it's intended purpose, rendering the machine basically useless. With our side frame repair kit you can install a supporting cradle to properly support this roller and get another lifetime out of the machine. This process is simple and straightforward but does require some moderate mechanical skills. The kit comes with all of the parts necessary and an instructional guide for the technician carrying out the installation.
