Stem Casters for Metro Super Erecta Carts — Four Material Options for Heavy-Duty Mobility

Stem Casters are replacement wheels designed for Metro Super Erecta carts, delivering reliable mobility across warehouses, kitchens, and institutional environments. Available in four material variants and sold individually, they let you tailor performance to your floor and load needs. The polyurethane version is pictured above.

Features

• Resilient (black hard rubber) – 800 lb per cart; High modulus (black soft rubber) – 800 lb per cart; Polyurethane (grey) – 1200 lb per cart; Polymer housing (all-polymer, no metal) – 1200 lb per cart.
• Designed for Metro Super Erecta frames and shelving systems.
• Replace or upgrade carts one caster at a time for flexible maintenance.
• Approximately 2.5 lb per caster with a 5 in height.
• Polymer housing option features an all-polymer build with no metal components, reducing corrosion concerns.

Benefits

• Choose resilient or high modulus for smoother rolling and better floor protection on lighter loads, or opt for polyurethane or polymer housing for higher capacity and longer wear life on heavy-duty carts.
• 800 lb per cart for rubber variants and 1200 lb per cart for polyurethane and polymer housing provide a safer, more versatile solution for heavy carts in busy environments.
• All-polymer housing variants reduce metal exposure to moisture and corrosion, simplifying upkeep in damp or cleaned facilities.
• Since casters are sold individually, you can mix and match materials across a fleet to optimize performance without replacing entire carts.
• Ideal for moving inventory in warehouses, supporting mobile prep stations in kitchens, transporting supplies in labs, or servicing janitorial carts with reliable, quiet rolling.
