Escalator Rollers

Escalator Rollers
DI T&I has developed a full range of urethane rollers used in OTIS escalators, including step rollers, chain rollers, and guide rollers, and continues to supply these products to OTIS. In particular, we have introduced an advanced manufacturing process in which urethane is directly molded onto the bearing for step rollers. This innovation significantly improves productivity while reducing costs compared to conventional methods. To ensure consistently high quality, all step rollers undergo rigorous inspection using durability testing equipment and urethane material testing systems. All escalators installed at Incheon International Airport are equipped with DI T&I components, demonstrating the proven quality and reliability of our products.

The products listed below represent our main offerings. We also provide customized specifications to meet specific customer requirements upon request.
