The JET cm9-06-37 is a half nut replacement part designed for use in JET lathes and similar machine tool equipment. The half nut engages the lead screw on a lathe to drive the carriage during threading operations. It is a wear component subject to repeated mechanical engagement and disengagement, making it a common service replacement in shop maintenance. Machinists and machine tool technicians typically source this part when the existing half nut shows signs of thread wear, slop, or failure to engage the lead screw cleanly.
This part is intended for use in threading and turning operations on compatible JET lathe models. It fits into the carriage apron assembly and works in conjunction with the lead screw to produce accurate thread pitches. Shops running production threading work or older lathes with accumulated wear will encounter this as a routine maintenance replacement. Installation is performed during scheduled downtime or corrective maintenance when carriage feed accuracy is compromised.
Designed as an OEM-style replacement half nut for JET lathe equipment. Refer to your machine's parts diagram using part number cm9-06-37 to confirm fitment before ordering.
Installation of a lathe half nut should be performed by a qualified machinist or machine tool technician familiar with carriage apron disassembly. Disconnect and lock out power to the lathe before beginning any internal apron work. Refer to the OEM service manual for disassembly sequence and proper adjustment of half nut engagement clearance. Improper installation can result in thread pitch errors or accelerated wear on the lead screw.
