A230-0587-X002 - 92x25mm 24V Cooling Fan Assembly Yellow Bracket + A90L-0001-0488 For Fanuc CNC Robot Control Cabinets

A02B-0260-C021 - 92x25mm 24V Cooling Fan Assembly Yellow Bracket + A90L-0001-0488 For Fanuc CNC Robot Control Cabinets

A02B-0260-C021 is a complete 24V cooling fan assembly used in Fanuc CNC control systems and robot controller cabinets. This module combines the yellow 2-slot mounting bracket with a high-reliability NMB 92mm fan (3610ML-05W-B49, Fanuc PN A90L-0001-0488) to provide continuous airflow across control boards, drives, and power electronics.

Designed for harsh industrial environments, this assembly is a direct drop-in replacement for existing A02B-0260-C021 fan units in Fanuc 16/18/21-series CNC controls and many R-series robot controllers, minimizing downtime during service or preventive maintenance.

✅ Confirmed Compatibility

Please note that the following list is not exhaustive. Compatibility depends on your system’s specific configuration. It’s essential to verify compatibility with your system or controller manufacturer prior to installation.

✔️ Fanuc CNC Controls (Rack-Type Controllers):
Series 16A, 16B, 16C, 18A, 18B, 18C, 21A, 21B, 21C, 15i, 16i-M, 16i-T, 18i-M, 18i-T, 0i-MB and other similar rack-based Fanuc CNC controller units that specify A02B-0260-C021 as the system fan module

✔️ Fanuc Robot Controllers:
R-J3iB, R-30iA, R-30iB robot controller cabinets that use the A02B-0260-C021 fan unit for system cooling

✔️ Fanuc System Racks / Control Cabinets:
2-slot Fanuc controller racks and system modules where A02B-0260-C021 (or A90L-0001-0488 fan within this assembly) is listed as the required system fan or fan module

If your existing module label shows A02B-0260-C021 or the fan inside is marked A90L-0001-0488 / 3610ML-05W-B49, this assembly is intended as a direct replacement.

⚙️ Fit Notes

• Match the part number on your existing fan module: if your current assembly is labeled A02B-0260-C021 (or bracket ID A230-0587-X002) this unit is designed as a drop-in replacement.
• You can also confirm by checking the fan inside your existing module; it should be marked 3610ML-05W-B49 and/or A90L-0001-0488.
• Ensure the replacement is installed in the same orientation as the original to maintain correct airflow direction through the controller or cabinet.
