Bearings for Air Conditioning/HVAC UnitsDistributor Bulletin 501 Air Handling units represent a significant number of applications for Ketchie-Houston Bearing Units. From designs which might be found captured in a dedicated floor of a high-rise building to units mounted on roofs or along the side of shopping mall, manufacturing facilities, and office building, special purpose bearing units are supporting the rotating components. Ketchie-Houston has a broad line of those units. Older designs like Claridge® Fan units with shaft diameters from 1 1/16 to 3 11/16 inches are in stock. These are sometimes referred to with the industry designation LSAOC or RSAOC. Carrier® and York® designs sometimes use heavy series catalog units with high base to center heights design. Shaft diameters range from 1 15/16 inches to 2 15/16 inches. Baltimore Aircoil® and Evapco® both use low base to center catalog heavy series bearing units on a horizontal shaft applications. For vertical shaft applications, these units are modified to use water repelling flinger collars. Shaft diameters range from 1 3/16 inches to 2 15/16 inches. Buffalo Forge® and Hauck Manufacturing® on high speed fans use one Fixed and one Floating unit on each shaft. These are often oil lubricated. Shaft sizes run all the way to 3 15/16 inches. Often it appears that the only source for replacement bearings is in the fan manufacturer or his local representative. In reality, Ketchie-Houston, through your local bearing distributor, can supply most of these units. If we have not already manufactured the unit you require, we might be able to reverse engineer the product and deliver it a short period. For More Information Contact: |
