Stem Casters — 1" Post Fit, Four Material Options

Stem Casters are a versatile solution for carts and trolleys needing robust support and smooth floor contact. Designed to fit standard 1" diameter hollow bottom posts, these casters are sold individually and offered in four material options to match your application—resilient rubber, high-modulus rubber, grey polyurethane, and a fully polymer housing.

Features

• Fits 1" diameter hollow bottom posts
• Material options: resilient black hard rubber; high modulus black soft rubber; grey polyurethane; 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 variants

Benefits

Choosing the right stem caster affects maneuverability, floor protection, and load handling. The resilient rubber option provides solid durability with good floor contact, while the high-modulus rubber balances resilience with a tighter ride for busy environments. For heavier or more frequent loads, the grey polyurethane variant delivers higher weight capacity (up to 1200 lb per cart) with smooth rolling characteristics. The polymer-housing version eliminates metal components, offering corrosion-resistance and suitability for clean environments. With four material choices, you can tailor caster performance to floor type, noise preferences, and workload, ensuring your carts move easily and withstand daily use.

Ideal use cases include hospital supply carts, industrial trolleys, lab equipment carts, and service carts in commercial spaces. Since each caster is sold individually, you can precisely match the number of casters to your cart’s weight distribution and turning needs, upgrading or replacing only where necessary. When selecting, consider post compatibility, load distribution, and the environment to maximize longevity and performance.
