Stem Casters — Heavy-Duty Single-Wheel Solutions for Industrial Carts

Stem Casters are rugged, single-wheel mobility components designed for heavy-duty carts and trolleys. Available in four material variants, they deliver dependable rolling performance across warehouses, workshops, and work environments that demand durability and ease of maintenance.

Features

• Material variants to suit your floor and load needs:
  • Resilient: black hard rubber, 800 lb per cart capacity
  • High modulus: black soft rubber, 800 lb per cart capacity
  • Polyurethane: grey wheel, 1200 lb per cart capacity
  • Polymer housing: all-polymer construction (no metal) with 1200 lb per cart capacity
• Sold individually, allowing precise replacement or customization of existing carts
• Approximate weight: ~3 lb per caster; overall height: ~5 inches
• Aligned with Metro Heavy-Duty Stem Casters line for reliable, industrial-grade performance

Benefits

These stem casters are designed to optimize mobility while supporting demanding workloads. The polyurethane and polymer-housing variants offer the highest load capacity (up to 1200 lb per cart) and enhanced wear resistance, making them ideal for heavy-duty warehouse and manufacturing environments. Polymer housing eliminates metal components, reducing corrosion risk and simplifying cleaning in sanitizing or maintenance-focused spaces.

Resilient and high-modulus rubber options provide different floor interactions: choose the harder resilient option for load stability and impact absorption on rough floors, or the softer high-modulus variant for quieter operation on smoother surfaces. With independent replacement options, you can refresh a fleet without replacing entire carts, improving uptime and overall equipment lifecycle.

Ideal for heavy carts used in tool rooms, maintenance stations, supply carts, and other mobile setups where dependable flooring interaction, straightforward maintenance, and predictable load handling matter most.

Practical tips: match the caster material to floor type and noise considerations; select the 1200 lb capacity variants for high-load applications, and opt for the polymer housing version when corrosion resistance and cleaning ease are priorities. Ensure compatibility with your cart’s stem size and mounting configuration for a secure, long-lasting fit.
