Stem Casters for Heavy-Duty Carts

Stem Casters are purpose-built wheels designed to attach to carts and trolleys, delivering reliable mobility in demanding environments. Available in four tire and housing configurations—resilient (black hard rubber), high modulus (black soft rubber), polyurethane (grey), and a polymer housing (all polymer, no metal)—they offer versatile options for warehouses, workshops, and manufacturing floors. Sold individually, these casters are a flexible solution for upgrading or replacing cart mobility.

Benefits

• Choose the tire compound that best matches your floor and load: hard rubber for rugged floors, soft rubber for vibration damping, or the durable, wear-resistant polyurethane for higher impact resistance.
• Polymer housing removes metal components, reducing corrosion risk and making these casters suitable for clean environments or applications where metal is undesirable.
• High load capacities—up to 1200 lb per caster—allow you to consolidate carts and reduce the number of wheels required, improving overall workflow and maintenance costs.
• Versatile option set within a single product family: mix-and-match tire types on different carts to meet varying use cases without changing hardware.
• Easy replacement and upgrade path: you can upgrade individual casters as needs change, without replacing an entire cart system.
