SKF
Ball Bearing Units for Air Handling Applications
SKF ball bearing units for air handling are engineered specifically for fans, blowers, and air handling units (AHUs) in HVAC systems. These units incorporate low-noise deep groove ball bearings or Y-bearings with optimised grease and sealing for vertical shaft operation and moderate temperatures. Housings are often light, compact designs in cast iron or pressed steel, with vibration isolation features. They ensure quiet, reliable operation in commercial buildings, hospitals, and industrial ventilation. The pre-greased, sealed units minimise maintenance in hard-to-access ceiling or duct locations. SKF designs for long service intervals, matching the life expectations of modern continuous-duty HVAC equipment.

Trusted by Industry Leaders
Low-Noise Optimisation
Special cages and grease formulations reduce sound levels.
Vertical Shaft Fitness
Grease retention for vertical or inclined fan shafts.
Longevity Grease Fill
Temperature-stable lubricant for 3-5 years of continuous operation.
Corrosion Resistance
Zinc-coated or painted housings withstand humid air streams.
Vibration-Dampening Housings
Minimised structure-borne noise transmission.
Standard Dimensions
Interchangeable with common HVAC motor and fan frames.
Bearing Solutions for HVAC Fan Efficiency
Energy-efficient fans operate at higher speeds. SKF’s low-friction sealed deep groove bearings reduce motor load and heat, contributing to overall system SEER ratings. Units are validated for continuous duty at speeds typical in modern ECM-driven fans.
Maintenance Accessibility in Air Handling Units
AHU bearings are often located inside insulated casings. SKF’s greased-for-life bearing units eliminate the need for periodic relubrication access ports, simplifying duct and casing design while maintaining bearing reliability.
