Double Edge Ring Slides & Segments
HepcoMotion double edge ring segments are cut from complete 360° ring slides and held in stock in nominal 90° and 180° segments*1. Any length segment can be cut to customer's special order and additional holes drilled as required. Although suitable for most applications, slight out of roundness and flatness may be experienced with slide rings and segments in their free unmounted condition. This may be overcome by installing against a register and bolting to a flat surface, True shape rings and segments are available on request.
