Honda 91102-960-010 Radial Ball Bearing (PA641-4)

The Honda 91102-960-010 Radial Ball Bearing (PA641-4) is a genuine OEM component designed for the HR21 lawn mower. As a direct Honda OEM part, it is manufactured to the same specifications as the original bearing installed at the factory, ensuring a correct drop-in fit without modification. Buyers should confirm their unit's serial number against the fitment table to verify this bearing is the right match for their specific HR21 configuration.

Key Features

• Genuine OEM Construction — sourced directly from Honda, this bearing meets the original dimensional and load tolerances specified for the HR21 lawn mower, not an approximation of them.
• Correct Variant Match — the PA641-4 designation identifies a specific bearing grade and size; confirm this code matches your original part before ordering to ensure proper fit and function.
• Smooth Rotational Performance — a worn or failing radial ball bearing introduces drag, vibration, and uneven load transfer; replacing it with this OEM part restores smooth, low-friction rotation.
• Serial Number Verification Recommended — Honda supersedes bearing part numbers at production breaks, so check your HR21's serial number against the compatibility table before purchasing.

A radial ball bearing supports a rotating shaft by carrying loads perpendicular to the shaft's axis, allowing components to spin freely with minimal friction. In a lawn mower like the HR21, bearings are used at key rotating points to keep drivetrain and blade-deck components turning smoothly under load. When a bearing wears, loses its grease, or develops play, it causes vibration, noise, and accelerated wear on surrounding components — making timely replacement important for keeping the mower running as intended.
