We used it for the old sliding door car of TOSTEM. (It is a door before the Heisei first year) Although the tire size was 36 mm specification, the difference between the height adjustment function on the bracket side and the radius 0.5 mm did not become a problem at all. Even though I heard from Rikkilu (formerly TOSTEM), there are metal fittings but there are not only tires. Since ASSY is about 2,500 yen, it was good that only cars could be exchanged. Because it was a heavy disaster-prevention glass door, the initial tire was sliding while playing hard, but this time the tire does not sound so much. I would like to purchase again as the bearing decreases.
