Lau 38245001 3/4 Inch Oil Sleeve Bearing with Insulator

Product Description

The Lau 38245001 is a 3/4 inch oil sleeve bearing with insulator, designed for use in HVAC fan and blower motor applications. Oil sleeve bearings are a core component in direct-drive and belt-drive blower assemblies, providing smooth rotational support for motor shafts while reducing friction and wear over extended operating cycles. This bearing is manufactured by Lau, a recognized name in HVAC air movement components, and is built to meet the demands of professional installation and service work.

Oil sleeve bearings work by maintaining a thin film of lubricant between the shaft and the bearing surface. This lubrication film absorbs load, dampens vibration, and prevents metal-to-metal contact during motor operation. Over time, bearings wear out due to heat, contamination, or lubrication loss, leading to increased noise, shaft wobble, or motor failure. Replacing a worn bearing with a correctly sized unit like the 38245001 restores proper shaft alignment and extends motor service life.

The insulator component on this bearing helps isolate vibration and reduces noise transmission to the surrounding housing or mounting structure. This is particularly important in residential and light commercial HVAC equipment where noise levels are a concern. The 3/4 inch shaft size and 1-27/32 inch outside diameter make this bearing compatible with a range of standard blower motors used in furnaces, air handlers, and ventilation fans. HVAC technicians and service professionals will find this a reliable direct replacement for worn or failed sleeve bearings in the field.

• 3/4 inch shaft bore size fits standard blower and fan motor applications
