Lennox 86H56 Ball Bearing

Standardize your blower assembly or motor mount with the Lennox 86H56, a high-performance rubber mounted cartridge ball bearing engineered for heavy-duty HVAC applications. This OEM Lennox replacement part features a precise 1 inch bore diameter and is physically identical to the Lennox 86H5601. Designed by Timken (Model RCSM-1 A4233), this bearing assembly includes a secure locking collar to ensure positive shaft retention and eliminate slippage during high-torque operation.

For technicians servicing 5 HP motors or large-scale air handlers, the Lennox 86H56 ball bearing provides critical vibration isolation and HVAC noise reduction. The integrated rubber cartridge acts as a shock absorber, dampening harmonic resonance that typically causes premature wear on blower shafts and motor housings. This pre-lubricated 1" bore ball bearing is compatible with a wide range of Lennox, Armstrong, and Ducane equipment, supporting optimal mechanical efficiency in both commercial and residential units.

• Vibration Isolation: The rubber-mounted cartridge design significantly reduces mechanical hum and system vibration.
• Mechanical Compatibility: Direct cross-reference for part numbers 86H5601, R43832-001, and R07070B001.
• Secure Shaft Fit: Includes a high-grade locking collar for stable 1-inch shaft alignment and reduced run-out.
• Industrial Build: Engineered for high-speed rotational stability in 5 HP motor applications and belt-drive blowers.

What is the difference between Lennox 86H56 and 86H5601?
Technically, they are the same component. The 8656 is the current production number and serves as a direct replacement for the legacy 86H5601 part number without requiring any modifications to the mounting bracket.

Can this bearing be used in non-Lennox units?
Yes, as long as the shaft diameter is exactly 1 inch and the housing accommodates a rubber cartridge-style bearing. It is frequently found in Armstrong, Concord, and Ducane air handlers.

How do I ensure the locking collar is installed correctly?
The locking collar should be tightened in the direction of shaft rotation and secured with the set screw to prevent the inner race from spinning on the shaft, which is a common cause of shaft scoring.
