Stem Casters — Heavy-Duty, Four Material Options for Carts and Equipment

Stem Casters are built to replace worn wheels on carts and equipment that routinely carry heavy loads. Available in four material configurations, they balance durability, floor protection, and smooth maneuvering across industrial floors. Sold individually and part of the Metro Super Adjustable Casters family, they’re designed to fit demanding environments where reliability matters.

Features

• Resilient option in black hard rubber; High Modulus option in black soft rubber; Polyurethane option in grey; Polymer housing with all-polymer construction (no metal).
• 800 lb per cart for resilient and high modulus models; 1200 lb per cart for polyurethane and polymer variants.
• 5 inches tall — a compact profile that pairs with a wide range of carts and shelving.
• Approximately 3 lb per caster, making replacements manageable without adding excessive overall weight.
• Integrated brake option available, enabling secure, parked positioning when needed.
• Stem casters designed for straightforward replacement; sold individually to allow precise, per-cart customization.
• The polyurethane variant is the example shown in product imagery.
• Part of the Metro Super Adjustable Casters lineup, designed for versatility and adjustability in busy workspaces.

Benefits

Choosing the right Stem Caster material matters for both performance and longevity. The four options let you tailor floor interaction, noise levels, and durability to your application:

• — Hard rubber (resilient) handles rougher floors with solid roll resistance, while soft rubber (high modulus) reduces shock transfer and minimizes floor scuffing on sensitive surfaces. Polyurethane offers a middle ground with excellent wear resistance and quieter operation, suitable for high-traffic areas.
• — All variants deliver strong load support, with 800 lb per cart for resilient and high modulus configurations and up to 1200 lb per cart for polyurethane and polymer housing models, enabling reliable performance for heavy carts and equipment.
• — The all-polymer housing eliminates metal components, reducing corrosion risk in humid or wash-down environments and simplifying maintenance over time.
• — Whether you’re outfitting a warehouse cart, tool trolley, or lab cart, you can pick a material that best matches floor type, noise tolerance, and desired lifespan.
• — Since casters are sold individually, you can combine materials to create a multi-zone mobile system that uses resilient wheels where floors are rough and polyurethane or polymer wheels where floor protection and load stability are paramount.
• — For high-traffic areas with smooth concrete or epoxy floors, polyurethane or polymer options often deliver the best balance of durability and quiet operation. For rougher shop floors, consider resilient or high-modulus rubber to absorb impact while maintaining mobility.

Ideal for maintenance carts, equipment trolleys, and industrial carts that require dependable, heavy-duty caster performance. With a choice of materials and a built-in brake option, Stem Casters help you keep mobility precise and controlled while protecting floors and extending caster life.
