Semi precision bearings are manufactured for the specific purpose of having very large clearances to survive in rough environments where a precision bearing would fail. For applications such as wheelbarrows, lifting trolleys and lawnmowers the wheel bearings aren't travelling at high speed the semi-precision bearing works perfectly.
