Features
Instead of relying on springs, which require manual tensioning and adjustment, Ultra™ Roller Guides employ a unique isolator that has been proven to reduce lateral cab vibration by as much as 50 percent. The Ultra™ Roller Guides’ self-adjusting feature tolerates rail misalignments of up to ¼ in. (7 mm) per 16 feet (5 meters) of rail section. This means more consistent ride quality as well as a significant reduction of elevator downtime over the life of the installation.

Applications
Ultra™ Roller Guides serve as a direct replacement for original Otis equipment and are easily adaptable to other existing equipment. They are standard on new Otis geared and gearless elevators. Ultra™ Roller Guides are designed for loads of up to 5,500 lbs. (2,500 kg) and speeds of 350-1,800 feet per minute (1.6-9.0 m/s).
