Whether you are performing a scheduled HVAC blower motor maintenance or responding to a bearing failure in a Reznor heater, this component provides the high-tolerance fit required for quiet, efficient operation across various industrial air handling applications.

• Precision Engineered 1 7/16" Bore: Ensures a secure, zero-slip fit on the blower shaft to minimize eccentric motion.
• Heavy-Duty Industrial Build: Rated for continuous use in Reznor HVAC systems and demanding commercial heating environments.
• Vibration Mitigation: Enhanced internal race design reduces mechanical noise and prevents stress transfer to the blower motor.
• Direct OEM Compatibility: Replaces Reznor part 170108 exactly, streamlining installation without the need for field modifications.

• What are the signs this bearing needs replacement? Listen for high-pitched squealing, grinding, or increased cabinet vibration. Physical shaft play or visible grease leakage are also definitive indicators.
• Is this bearing pre-lubricated? While most industrial bearings come factory-packed, always verify the technical specifications for re-greasing intervals to ensure maximum service life.
• Which Reznor models use the 170108 part? This part is widely used in larger Reznor unit heaters; always cross-reference your specific model and serial number before installation.
