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