I ended up with a lot of brand new SAC wide belt sander contact rollers of various widths and diameters. These fit SAC Smart, Concept, RTE and possibly other SAC models. If interested reach out and we can figure out if any of these will fit your machine. $500 price is per roller.
Here's a list of what I have:
1 - 833.9723.10.85_Dia. ???, Length 970mm, Shore 85 (SAC Smart series)
1 - 00.12852.10.65_Dia. 190mm, Length 1100mm, Shore 65
1 - 00.12852.10.35_Dia. 190mm, Length 1100mm, Shore 35
1 - 00.12855.10.35_Dia. 225mm, Length 1100mm, Shore 35
1 - 00.12473.10.85_Dia. 185mm, Length 1350mm, Shore 85
1 - 00.12473.10.65_Dia. 185mm, Length 1350mm, Shore 65
1 - 00.12473.10.35_Dia. 185mm, Length 1350mm, Shore 35
1 - 00.12452.10.35_Dia. 225mm, Length 1350mm, Shore 35
I also have an used SCMI contact roller that is in decent condition. I am surprised it was removed from a machine as it could easily be dressed. It is 5.525" in diameter, 45.25" long and fits a Sandya 5 sander. $100 for the used SCMI contact roller.
I am willing to crate these up for shipment, freight cost would be in addition to the final agreed upon sales price.
