Albion Inc. Zoro Select 26Y366 5 in 350 lb Polyolefin Caster Wheel

5 in 350 lb Polyolefin Caster

This Albion Inc. Zoro Select 26Y366 caster wheel uses a polyolefin tread on a polypropylene core. It carries a 350 lb load rating and fits a 3/8 in axle with the included spanner bushing. The 5 in diameter wheel has a 1 1/2 in width and a 1 9/16 in hub length. Its non-marking design suits carts and wheelbarrows used on finished floors.

Upgrading from lower rated wheels

Replacing casters rated below 300 lb with this 350 lb model adds capacity for heavier loads on the same equipment. The jump is worth it when current wheels deform or fail under sustained weight. Buyers who need a load rating above 999 lb cannot use this wheel. Those requiring a different axle size or tread material must select another product.

Plain bore polyolefin limits

The plain bore with spanner bushing relies on the axle for rotation rather than an internal bearing. Polyolefin at 65 Shore D hardness resists flat-spotting but transmits more vibration than softer treads. It operates within a 300 to 999 lb load rating range for this wheel class. Environments with sustained impact or chemicals not covered by the Prop 65 notice may reduce service life.
