Stem Casters - Heavy-Duty Options for Cart Systems

Stem Casters are rugged wheels built for carts and trolleys in demanding environments. Available in four material options—resilient rubber, high-modulus rubber, polyurethane, and a polymer housing—these casters deliver reliable performance for heavy loads while protecting floors.

Features

• resilient (black hard rubber), high modulus (black soft rubber), polyurethane (grey), and polymer housing (all polymer, no metal).
• Load capacity: 800 lb per cart for resilient and high-modulus variants; 1200 lb per cart for polyurethane and polymer variants.
• Mounting and configuration: stem caster designed for carts; sold individually to let you configure per your needs.
• Visual reference: Pictured above is the polyurethane caster.
• Finish and construction: polymer finish with housing entirely in polymer (no metal components).
• Dimensions: height 5 in; weight 2 lb per caster.
• Identification: SKU: 5PC; Category: Metro Heavy-duty Stem Casters.

Benefits

Choosing the right stem caster matters for uptime and floor care. The resilient rubber option offers durability in rough environments, while the high-modulus variant provides smoother rolling with strong resistance to wear. For the heaviest loads and longer wear life, the polyurethane and polymer-housing options deliver higher load ratings (up to 1200 lb per cart) and corrosion-free performance thanks to their non-metal construction.

These stem casters are ideal for platforms like warehouse carts, tool carts, and production-line trolleys where you need dependable maneuverability and predictable performance across varied floors. By selecting the material that best matches your floor type and load, you can extend equipment life, reduce maintenance, and keep operations moving smoothly.

Tips for best results: match the caster material to your floor (harder rubbers for rough floors, softer rubbers for sensitive surfaces), ensure your cabinet or cart weight stays within the rated per-caster capacity, and verify the stem size fits your equipment. This line offers the flexibility to tailor a cart system precisely to your workflow with reliable, purpose-built performance.
