Bosch 2604010826 Spare Part - Armature
1604010B6R supersedes older part numbers: 2604010826
Original Bosch armature / rotor 1604010B6R — a direct-fit replacement rotor (armature) designed to restore motor performance in compatible Bosch foam‑cutters and grinders. The precision‑wound rotor includes the commutator and rotor fan assembly as used in the factory motor, so it restores smooth running and reduces sparking compared with a worn or damaged rotor.
Fitment: listed for the Bosch GSG 300 foam/rubber cutter (Bosch type numbers such as 0601575103 / 0601575143 are shown in parts diagrams that reference this rotor). If your tool is a GSG 300, this part number (also shown as 1.604.010.B6R / 1604010B6R) is the original Bosch rotor used in the exploded parts lists.
Notes for the repair: this is the genuine Bosch rotor/armature specified to replace the original (it’s also referenced as a replacement for part 2 604 010 826 in parts), so you’ll want to install it with fresh brushes and verify correct bearing seating and axial play during reassembly to get full life from the repair. This is the kind of original Bosch component you look for when sourcing reliable parts for power tools.
What you get: one original Bosch 1604010B6R armature (rotor) manufactured to Bosch tolerances — ready to drop into the motor housing for a like‑for‑like repair.
