How to find the right Lawn Mower Bearings AI guide
Written by an AI model from its trained knowledge.
What the AI looks for in Lawn Mower Bearings
- Size designation
- Read the number stamped on the old bearing. In the 62xx and 60xx series, codes 00 to 03 mean bores of 10, 12, 15 and 17 mm. From 04 upward, the bore in mm is the last two digits times five. Any maker's bearing with the same designation is dimensionally interchangeable.
- Seal type
- Use 2RS (rubber sealed both sides) for deck spindles and wheels rather than ZZ (metal shielded) Grass clippings, dust and wash water get past metal shields, and contamination is the main cause of mower bearing failure.
- Flanged vs plain
- Match a flanged bearing with a flanged one of the same flange diameter, which is common on deck and caster wheels The flange locates the bearing in the wheel, and a plain bearing will walk out.
- Metric vs inch
- Confirm whether the shaft is metric or inch, for example a 1/2 in axle versus a 12 mm axle Inch and metric sizes are close enough to look right but give a sloppy or impossible fit.
- Failure check
- Replace a bearing if the spindle or wheel shows radial play, grinding or roughness when spun by hand A failing spindle bearing can damage the spindle housing and shaft if run until it seizes.
Brands that matter

What to avoid

- ZZ shielded bearings in deck spindles
- Hammering on the inner race when pressing a bearing in through its outer race
Questions
Can I buy a generic bearing instead of the OEM part?
Yes, if the stamped designation and seal type match. Standard deep groove sizes are interchangeable across reputable bearing makers. Some OEM spindle bearings are non-standard, though, so cross-reference those first.
