Product Description

 1. Heavy duty 'nested rails' are full channels and I-sections specially rolled to provide maximum section strength where it's needed.
2. Canted rollers provide low friction rolling contact under normal and unbalanced conditions caused by uneven carriage loading.
3. Slide thrust roller on the carriage fork bar prevent inner rail spread when unbalanced loads are handled.
4. Wrap around tie bars are precision wedded to outer channels. these thick tie bars minimize rail spread and twist.
5. Carriage and upright rollers are canted in opposite directions from top to bottom. this design helps rollers operate in the strong radius area and upright rails while providing rolling contact under varied load conditions. carriage and upright rollers feature flexible seals that aid in retaining lubricant as normal wear occurs.
6. Roller shims are inserted on the roller shafts so proper operating clearance can be maintained. the shimming procedure is simple and effective for both carriage and upright rollers.
