Product Identity
The Zoro Select 20PM12 is a 4 inch conductive rubber wheel mounted on a plastic core, rated for 250 lb loads with a 75 Shore A durometer. Precision ball bearings support smooth rotation for wheelbarrows and utility carts. The non-marking tread protects finished floors during indoor or outdoor use. A 3/8 inch axle bore and 1 1/2 inch hub length define the mounting interface.
Suitable Applications
This wheel suits light-duty material-handling equipment that requires quiet, non-marking mobility on hard surfaces. The soft 70 Shore A rubber compound absorbs vibration on uneven ground. Buyers needing higher load capacity or extreme temperature resistance should evaluate alternative wheel constructions. The conductive tread addresses static-dissipation requirements in sensitive environments.
Deciding Specification
The 250 lb load rating per wheel is the primary limit for equipment design. Exceeding this figure risks premature tread separation or core failure. Confirm the total cart weight divided by wheel count stays within this rating before purchase. The 3/8 inch axle size must match existing brackets or replacement axles.

Questions about this item
How much heat or noise does the 75 Shore A wheel generate during all-day use?
The caster wheel has no motor or electronics, so it produces no heat and no audible noise regardless of how long it rolls.
What axle size must the cart or wheelbarrow already have for the 3/8 in bore to fit?
The wheel requires a 3/8 in axle; the hub length is 1 1/2 in and no spanner bushing is included.
Will the 250 lb load rating and 4 in diameter work with an older wheelbarrow frame?
The 4 in diameter, 1 1/4 in tread width and 250 lb capacity match many legacy wheelbarrow and cart frames that accept a 3/8 in axle.
