This complete assembly is non-conductive and different from our standard square drive assembly that comes installed on Series SRH, TXH and LXH motors. It was developed by our engineers for equine dentists and other users with similar applications. Both the inner shaft and outer sheath have plastic motor connectors in place of our standard metal components. This assembly can be used to replace broken or worn shafts and sheaths on these motors:
M.SRH, M.SRMH, M.SRBH 
M.TXH, M.TXMH, M.TXBH
M.LXH, M.LXMH M.LXBH

Assembly comes pre-lubricated from factory.
