MadeWell Crown Rollers

Whether used on their own or paired with our DualVee Motion Technology® product line, these crown rollers are made of high quality materials that stand the test of time in a variety of application environments. Designed to run on flat surfaces or in C channel track, the uses are limited only by your imagination.

MadeWell Crown Rollers can be used in conjunction with DualVee® Guide Wheels for applications requiring pairs of linear guide systems operating in parallel. Such arrangements are used when wide spans or high moment loads need to be supported. One slide uses DualVee Guide Wheels with vee channel track and the other uses MadeWell Crown Rollers with C channel track. Working in unison, the vee side serves as the primary guide while the crown roller side provides radial support to compensate for parallel misalignment. Because precise parallelism between paired guides is difficult to achieve, the usage of MadeWell Crown Rollers on one side instead of both sides using DualVee Guide Wheels compensates for mounting errors. To learn more, review the UtiliTrak® compact linear guide product catalog.
