Main Product Description
CMT 791.004.00 is the exact bearing item in the official Series 791 Spare Parts and Accessories family. The North American variation row specifies a 3/4-inch outside diameter, 1/4-inch bore, and 7 mm width. CMT’s metric table lists the same configuration as 19 × 6.35 × 7 mm.
The bearing functions as a guide, profile-control, or flush-trim component on compatible CMT router-bit assemblies. Verified official references include selected Series 7/8/906 flush-trim bits, 7/8/938 roundover bits, 7/8/914B round-nose bits, 7/8/965B classical-bead bits, 7/851B bowl-and-tray bits, 852B dado and planer bits, 7/8/901B mortising bits, and 7/8/948B plunge-ogee bits.
The bearing is separately orderable and does not automatically include the parent router bit, shield, screw, stop collar, spacer, or hex key. Related hardware changes by tool family and exact item row. CMT’s Series 791 safety guidance requires the black shield to remain right side up during reassembly so it corresponds with bearing rotation.

Compatibility & Installation Notes
Confirm exact Item Code 791.004.00 and dimensions 3/4 × 1/4 × 7 mm before installation. Use only on a compatible CMT assembly that explicitly lists this bearing. Inspect the bearing for roughness, play, shield damage, contamination, or binding; replace damaged components. Reassemble with the black shield right side up, use the exact shield, screw, stop collar, spacer, or key specified by the parent-tool row, and confirm free bearing rotation before use. The router bit and related fastening hardware are not included.
