Precision Bearing Pack of Two
This pack contains two precision bearings suited for wheelbarrows, carts and similar yard equipment. They are intended for homeowners and maintenance crews who need reliable rolling performance on outdoor tools. The bearings are supplied as a matched pair for straightforward replacement.
Thermals Noise and Power Draw
The bearings operate without an external power source and generate no audible noise during normal rolling use. Heat build-up is minimal under typical yard-load conditions, so no additional cooling or lubrication schedule is required beyond standard maintenance.
Build Fit and Freedoms
Each bearing accepts a hub up to one and three-eighths inch, allowing direct fit on many common wheel assemblies. The two-piece pack lets you service both wheels at once, freeing time for other tasks. No specialised tools or extra hardware are mentioned in the specifications.

Questions about this item
How do I install the 46U320 precision bearing onto a wheelbarrow hub up to 1-3/8 in?
Press the bearing onto the hub until it seats fully, then secure the retaining clip; the common mistake is skipping the clip and letting the bearing walk out under load.
What maintenance will the 46U320 bearings need over time?
Inspect the seals each season; if grit has entered or the bearing feels rough, replace the pair — they are not designed for re-greasing.
What limit appears first when the 46U320 bearings run continuously under heavy cart loads?
Heat buildup in the sealed races causes the grease to break down, leading to increased drag and eventual seizure.
