Frequently Asked Questions
Are the common 80 mm and 100 mm family rollers interchangeable?
Select the exact outer diameter, width, bearing, shaft and mounting configuration; a family reference alone does not establish fit.
Can the bearing code be identified from the blue centre in the photograph?
Confirm the exact bearing and bore from the selected configuration or mechanical drawing; appearance does not define the bearing code.
Does the roller alone establish the operating speed or load of an elevator?
Speed and load suitability depend on the selected roller version and complete guide or door-system configuration.
Does polyurethane tread establish a guaranteed noise level?
Noise and service behaviour depend on the selected compound, load, alignment, running surface and complete installation.
