The Stelron DS series unit incorporates two slide bars secured rigidly at both ends by blocks and passing through two sets of recalculating linear ball bearings which are mounted in a housing. The end blocks permit mounting of tools or actuating links or can serve as fixed supports when the housing assembly is used as a sliding member.
All DS units may be mounted in any position. Integral felt wipers, and mounting holes are included in the standard DS unit. Variations will be supplied when specifically requested. A mean clearance of approximately .001 inch between the shaft and bearings is provided but closer fits can be obtained if required.
