Fan BLOW 40×10 mm 24V sliding bearing — compact axial cooling fan

BLOW 40×10 mm 24V sliding bearing — compact axial cooling fan is a small-form-factor axial fan designed to provide continuous airflow in space-constrained electronic enclosures. With a 40×10 mm frame and 24 V nominal supply, the fan is intended for cooling PC components, small power supplies, communication devices and industrial control equipment. The sliding (sleeve) bearing construction provides a simple, low-cost solution for steady airflow and basic heat dissipation in compact installations.

Advantages

The compact dimensions allow installation where larger fans cannot fit, while the 24 V rating suits many industrial and telecom systems. Sliding bearing design reduces manufacturing cost and offers quiet, continuous operation under moderate load. The axial configuration delivers directional airflow for targeted component cooling and ventilation in tight spaces.

Suitable for

• Cooling small PC chassis and mini-ITX builds
• Ventilation of routers, switches and network devices
• Cooling of compact power supplies and DC-DC converters
• Airflow assistance in industrial control panels and enclosures
• Replacement of similarly sized axial fans in OEM equipment

Key specifications

• Frame size: 40 × 10 mm
• Fan type: axial
• Operating voltage: 24 V DC
• Bearing type: sliding (sleeve) bearing
• Application: cooling and ventilation for compact electronic devices

How to use

Install the fan in the intended airflow orientation, ensuring unobstructed inlet and outlet paths for effective ventilation. Mount using appropriate screws or clips compatible with the 40 × 10 mm frame, and connect to a stable 24 V DC supply observing correct polarity. Allow a brief run-in period for sliding bearings; ensure the fan is not subjected to excessive axial or radial loads during operation. For continuous duty applications, verify ambient temperature and enclosure airflow to prevent premature bearing wear.

Usage recommendations

For longer service life, operate the fan in a clean environment or add basic filtration to reduce dust ingress. Avoid frequent start-stop cycles and excessive vibration. When higher reliability or prolonged continuous operation is required, consider bearing type and replacement intervals as part of preventive maintenance.
