Stem Casters — Heavy-Duty Stem-Mount Wheels (4 Material Options)

Stem Casters are rugged, stem-mounted wheels designed for industrial carts, trolleys, and workstations. Available in four material options—resilient black hard rubber, high modulus black soft rubber, grey polyurethane, and a polymer housing (no metal)—these casters deliver dependable mobility for demanding environments. The polyurethane variant is pictured above. Each caster is sold individually as part of the Metro Heavy-Duty Stem Casters lineup.

Features

• Material options: resilient (black hard rubber), high modulus (black soft rubber), polyurethane (grey), and polymer housing (all polymer, no metal).

• Mounting: stem-mount design compatible with a wide range of carts and trolleys.
• Size and weight: each caster weighs about 2.5 lb with an overall height of 5 in.

Benefits

These stem casters are built to move heavy loads smoothly while protecting floors and reducing maintenance needs. Choose the resilient or high-modulus rubber for reliable performance on varied floor surfaces, or opt for the polyurethane option when you need higher load ratings and durable wear resistance. The polymer housing variant offers corrosion resistance and lighter weight, simplifying cleaning and upkeep in demanding environments.

Ideal for industrial carts, service trolleys, tool carts, and equipment carts that require dependable mobility and scalable load support. The four material options let you tailor performance to floor type, environment, and lifespan expectations—without compromising on maneuverability or ease of maintenance.

Why this matters: Unlike all-metal alternatives, these stem casters with polymer housing or rubber wheels minimize rust risk and floor wear, while polyurethane wheels provide quiet, long-lasting rolling for high-capacity carts. With up to 1200 lb per cart capacity in select variants, you can transport heavier loads with confidence and fewer replacements.
