Stem Casters: Heavy‑Duty, Stem‑Mounted Wheels for Carts

Stem Casters are versatile, stem‑mounted wheels designed to support heavy loads on carts and trolleys. Available in four material options to match floor type and environment, these casters are sold individually for flexible, customized configurations.

Features

• Material options: 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.
• Construction: polymer housing option provides metal‑free construction for corrosion resistance in moist or chemical environments.
• Dimensions: approximately 5 in height; unit weight around 3 lb; finish noted as resilient.
• Installation: stem‑mounted design and sold individually, allowing mix‑and‑match configurations.
• Product lineage: categorized under Metro Super Adjustable Casters; SKU 5MB; polyurethane variant is commonly pictured.

Benefits

Choose the right stem caster to optimize stability, floor impact, and longevity for your carts. The resilient and high‑modulus rubber variants excel on smoother surfaces while dampening shocks from uneven floors, reducing vibration and user fatigue. The polyurethane option delivers higher load capacity and durability on demanding, high‑traffic applications, while the all‑polymer housing minimizes corrosion risk in damp environments.

Key use cases include warehouse and maintenance carts, mobile workstations, lab trolleys, and classroom or shop carts. By offering four material choices and being sold individually, these casters let you tailor wheel hardness, noise levels, and load handling to each cart’s specific role—without overhauling your entire fleet.

Practical tips: assess your floor type and expected loads to select the optimal material (hard rubber for light impact, soft rubber for vibration damping, polyurethane for heavier loads). When upgrading, swap in a polymer housing variant if corrosion resistance is a priority. Since each caster is sold separately, you can replace only worn wheels rather than entire assemblies, keeping downtime to a minimum.
