More Information About This Product

About This Caster - 77520EZ

Use this 5-inch Pemco PolyKat swivel to bring tired shopping carts and retail carts back to a quiet, easy roll without replacing the whole cart.

The PolyKat is built as a cart caster replacement, so it threads in on a 1/2-inch-13 stem rather than bolting to a plate, dropping straight into a standard cart socket. The blue polyurethane tread is mechanically locked to the core so it will not peel away under constant use, and it rolls quietly, resists abrasion, and leaves no marks on store floors. A dual precision bearing, two ball races, keeps the roll smooth through the continuous duty a cart fleet sees. The 5-inch wheel handles thresholds and entry mats, and the 4-inch swivel radius keeps it nimble in aisles. It serves from -45°F to 180°F.

Ideal applications

  • Shopping and retail cart caster replacements on a threaded stem
  • Cart fleets needing a quiet, non-marking, easy-rolling wheel
  • High-cycle carts where a locked-on tread resists separation

Verify the stem thread fit, the load rating, and the part number against the Pemco spec sheet before ordering.

Pairs with: matching PolyKat cart casters on the other corners from the Pemco collection.

Wrong fit? Mounting to a flat deck instead of a stem socket? Choose a top-plate swivel in the Pemco collection.
