Stem Casters — Four Material Options for Heavy-Duty Carts

Stem Casters provide reliable mobility for industrial carts and service trolleys, with material options designed to match floor conditions, load requirements, and environmental needs. Sold individually, they’re a versatile solution for warehouses, workshops, labs, and campuses.

Features

• Material options: Resilient (black hard rubber), High Modulus (black soft rubber), Polyurethane (grey), and Polymer housing (all polymer, no metal).
• Weight capacity: 800 lb per cart for resilient and high modulus options; 1200 lb per cart for polyurethane and polymer housing.
• Finish and construction: Polymer finish option; polymer housing version eliminates metal components for corrosion resistance.
• Dimensions: 5 inches in height; approximately 2 lb per caster.
• Configuration: Casters are sold individually; polyurethane option is pictured as the reference.
• Category: Metro Super Adjustable Casters.

Benefits

Tailor your cart’s mobility to your environment and workload. The resilient and high modulus rubber options cushion impacts and protect floors on rough or uneven surfaces, while the polyurethane and all-polymer housing variants deliver higher load support (up to 1200 lb per cart) with enhanced wear resistance. The all-polymer housing minimizes metal exposure, reducing corrosion risk in damp or chemical settings and simplifying maintenance.

These stem casters are ideal for users who need flexible, durable mobility across multiple settings—whether you’re outfitting a warehouse fleet, a maintenance shop, a lab with sensitive floors, or an educational facility with heavy utility carts. By choosing the right material—soft rubber for quiet, smooth rolls; hard rubber for rugged floors; or polymer housing for corrosion resistance—you can optimize performance, longevity, and total cost of ownership.
