<p>Rollers or wheels mounted on axels within an integral block which support a predetermined load but which wheels flex and or deflect under shock or overloads. Whereas the block absorbs and saves the wheels from shock and overloads, is herein a "Rollo-flex" assembly. The Rollo-flex mounted in or on fitting tracks of overhead doors or retractable truck tarpaulins, affords significant and numerous benefits such as: vibration reduction, superior damping, low operational effort, and noise, greater load bearing, longer component service life and cost effectiveness</p> |
