Fan Prolech 50×50×10 mm 24V sleeve bearing 3-wire

Prolech 50×50×10 mm 24V sleeve bearing 3-wire axial fan is a compact cooling solution for small electronics and enclosures. Designed for 24V DC systems, this low-profile fan combines a narrow frame with a three-conductor connector that supports power and tachometer/control functions. The sleeve (sliding) bearing offers a simple, space-efficient option for continuous airflow where moderate noise and service intervals are acceptable.

Advantages

The fan’s compact 50×50×10 mm size makes it easy to install in tight locations while providing directed airflow for heat-sensitive components. The 24V rating is suitable for many industrial and telecom power systems. A 3-wire connection allows for speed monitoring or basic control alongside power delivery. The sleeve bearing construction keeps the design economical and slim, enabling installation in low-profile assemblies and small power supplies.

Suitable for

• Cooling small electronic boards and components
• Ventilation in compact enclosures and instrument cases
• Airflow in power supplies and DC-powered devices
• Replacement or retrofit in systems requiring a 24V low-profile fan

Key specifications

• Frame dimensions: 50 × 50 × 10 mm
• Operating voltage: 24 V DC
• Bearing type: sleeve (sliding) bearing
• Wiring: 3-wire connection for power and speed/monitoring
• Mounting: standard screw mounting for small fans (low-profile)

How to use

Mount the fan on a flat surface within the enclosure using appropriate screws that match the mounting holes. Connect the three wires to the host system according to the device wiring conventions: positive 24 V to the power lead, ground to the return, and the tachometer/speed-control wire to the monitoring or PWM input as required. Ensure airflow orientation points toward the area requiring cooling and provide adequate ventilation for intake and exhaust. Avoid pinching the cable and observe polarity to prevent damage.

Usage recommendations

For extended service life, mount the fan in locations with moderate ambient temperatures and clean airflow. Periodically inspect and, if necessary, clean accumulated dust from the blades and housing. If continuous low-noise operation or long maintenance intervals are critical, consider a fan with a ball bearing or fluid dynamic bearing as an alternative in future replacements.
