Bishop-Wisecarver Corp. - External Assembled Single Edge Ring Systems

When using HepcoMotion external single edge ring slides it is recommended that two concentric bearings should be placed 120º apart in order to provide a datum reference. The other bearings should be eccentric type. All eccentrics may be used where positional adjustment of the ring is required. Either ring or bearings can be the moving element. The HepcoMotion PRT2 eccentric bearings are of double eccentric design with sufficient throw to enable disengagement of the ring without disassembly. One or more lubricators may be fitted at convenient positions to take advantage of the increased load/life afforded by lubrication.

Manufacturing Notes	N/A For Dimension K and L : Short or long stud lengths are available for each size of bearing. Choose according to the required mounting plate thickness. For Drilling Position : Exact theoretical values have been given for `B`, `C` and `D`. Positional accuracy of dimension `B` will determine the axis of the ring. Positional accuracy for dimensions `C` and `D` are not normally critical. Holes for bearing studs should be reamed to tolerance F6 for a sliding fit.
