Stem Casters upgrade carts and trolleys with dependable mobility. They fit 1-inch diameter hollow bottom posts and are available in four materials—resilient black hard rubber, high-modulus black soft rubber, gray polyurethane, and a polymer housing—sold individually for easy, precise replacements.

Features

• Materials: resilient black hard rubber; high-modulus black soft rubber; gray polyurethane; polymer housing (all-polymer, no metal)
• Weight capacity: 800 lb per cart for resilient and high-modulus variants; 1,200 lb per cart for polyurethane and polymer variants
• Fitment: accepts 1-inch diameter hollow bottom posts
• Dimensions: approximately 5 inches in height

Benefits

Choosing the right stem caster balances floor impact, noise, and wear. Rubber options provide steady shocks and quieter operation on hard floors, while the polyurethane and polymer variants offer higher load capacity and longer wear life for heavier carts. The polymer housing delivers a lightweight, corrosion-resistant alternative to metal-bodied casters, helping simplify maintenance. These casters keep heavy carts mobile in warehouses, workshops, and maintenance environments, reducing downtime and improving workflow.

Use Cases & Compatibility

• Ideal for industrial carts, tool carts, mobile workstations, and service trolleys using 1-inch stem posts
• Suitable when choosing between floor-friendly rubber shades or higher-load polymer options
• Easy to replace by swapping in the same 1-inch stem caster on existing posts
