HepcoMotion double edge Ring Slides curved segments are cut from stock rings or segments. They are matched in essential respects with their corresponding track system straight slides and ground square on the ends to a specified dimension relative to their true shape. A clearance keyway and tapped hole facility is incorporated each end to provide a method of alignment when assembled together with the mating key of the track system straight slide*1. An additional fixing hole is provided adjacent to the keyway each end to give extra support at the join position for all segments except the TR12 93 & TR12 127. All track system curved segments are marked with a reference number and sequence number and are available in stainless steel for applications requiring corrosion resistance. Segments to any number of degrees can be supplied to cater for all track system configuration
