Abstract
Compact, lightweight design reduces side friction. Set of proposed two-axis track rollers enables sliding door to follow curved track in both directions without binding. Combination of cylindrical cam-follower-type roller and large ball end roller. Intended for use on sliding hatch covers on proposed Space Station Freedom, also useful on Earth to ensure ease and reliability of motion in sliding doors, windows, covers, and partitions.
