Lennox 93G97 Ball Bearing

The Lennox 93G97 Ball Bearing is a critical OEM replacement component designed for high-demand HVACR applications. Featuring a 1 3/16 inch bore and a 2 1/2 inch outer diameter, this precision-engineered bearing is built to handle the significant radial and axial loads found in commercial blower assemblies and industrial fan motors. As a heavy-duty rubber cartridge bearing (frequently cross-referenced as Timken LRCSM-1 3/16), it incorporates an eccentric locking collar to ensure a secure, slip-free attachment to the shaft, maintaining critical alignment even during high-torque startup cycles.

Field technicians will recognize the Lennox 93G97 for its compatibility with the GCS16 and CHA16 series, among other heavy-tonnage units. By reducing rotational friction and preventing shaft runout, this HVAC motor bearing helps eliminate the common issues of vibration, overheating, and excessive noise that lead to premature motor failure. When replacing worn bearings in Lennox blower motors, utilizing this genuine 1-3/16" bore ball bearing ensures the system maintains its original SEER ratings and operational efficiency without the mechanical drag associated with lower-grade aftermarket alternatives.

• OEM Compatibility: Exact replacement for Lennox part 93G9701, ensuring seamless fitment in GCS16-240 and CHA16-180 industrial units.
• Precision Tolerance: Engineered for minimal friction to prevent heat buildup and protect motor windings from thermal stress.
• Secure Locking: Features an eccentric locking collar for positive shaft engagement, reducing the risk of bearing spin or shaft scoring.
• High Load Rating: Designed specifically for belt-driven or high-load direct-drive HVAC applications requiring robust radial support.

Is the Lennox 93G97 interchangeable with standard industrial bearings?
While the dimensions may look similar, the 93G97 is a specific rubber-cushioned cartridge bearing (Timken LRCSM-1 3/16 style) designed to isolate noise and vibration in HVAC cabinets. Standard steel-to-steel bearings may transmit frequency noise throughout the ductwork.

What are the signs that a 1-3/16" blower bearing is failing?
Technicians should look for rhythmic screeching, increased amperage draw from the motor, or visible shaft play. If the locking collar has loosened, you may also see "dusting" or metal shavings around the bearing seat.

Does this bearing require field lubrication upon installation?
This is typically a sealed or pre-lubricated unit. Check the specific housing for a grease fitting; however, most 93G97 replacements are designed to be maintenance-free over their operational lifespan under normal conditions.
