HVAC Air Handling

Industrial fans and blowers are essential in many industries, generating continuous airflow for processes such as ventilation, heating, cooling, combustion, exhaust, drying, and air cleaning. They are widely used in food processing, power generation, cement production, and mining. Bearings in these fans and blowers typically operate at high speeds with relatively light loads and often face extreme temperatures and remote locations.

Mounted ball bearings are crucial in the HVAC (Heating, Ventilation, and Air Conditioning) and air handling sectors. They are integral to the performance and longevity of fans, blowers, heating equipment, and cooling towers. These bearings ensure optimal performance, minimize noise, and extend the lifespan of the equipment, making them indispensable in maintaining efficient and reliable HVAC systems.

LDK offers a wide range of products to meet the demands of HVAC and air handling applications. LDK “AH” series “Air Handling” mounted ball bearings has the same features as the standard LDK mounted ball bearing expect for the following air handling features.

• ✔100% noise tested to Electric Motor Quality(EMQ) standards.

• ✔AH housing Fit: Air Handling “AH” mounted ball bearings are manufactured with a controlled housing fit that allows the bearing to properly self-align when mounted on light-weight frames commonly found on air handling equipment.

• ✔Smaller bore tolerance allows for a tighter fit with the shaft. This in turn, reduces vibration and noise and dramatically increases bearing life.

• ✔An appropriate clearance is adopted which helps reduce the noise and vibration in high speed applications.

• ✔Nylon patched grub screw is proven to provide greater locking power between the bearing and the shaft.
