Jacobs JCM7417 Jaw Nut Unit Plain Bearing Drill Chuck 3

Product Description

The JACOBS JCM7417 is a jaw and nut unit designed as a replacement component for plain bearing drill chucks. This unit provides the jaw assembly and corresponding nut needed to restore proper clamping function to a worn or damaged chuck. It is a direct service part used by machinists, tool repair technicians, and industrial maintenance professionals who need to rebuild or refurbish a drill chuck rather than replace the entire assembly. The JCM7417 is compatible with Chuck Number 3 and is built to JACOBS specifications for consistent fit and reliable clamping performance.

This jaw and nut unit is intended for use in maintenance and repair applications where a plain bearing drill chuck has experienced jaw wear or nut damage. Plain bearing drill chucks are commonly found on drill presses, lathes, and hand drills used in light to medium industrial settings. Replacing the jaw and nut unit rather than the full chuck is a cost-effective approach in shop maintenance environments where equipment upkeep is performed in-house.

Installation Notes

Installation should be performed by a qualified machinist or tool repair technician familiar with drill chuck disassembly and reassembly procedures.

Follow the chuck manufacturer's service documentation for proper jaw and nut seating sequence to avoid uneven jaw alignment or chuck runout.
