Stem Casters for 1" Hollow Posts – Multi‑Material Options for Carts and Equipment

Stem Casters are purpose-built wheels designed to fit 1" diameter hollow bottom posts, ideal for utility carts, trolleys, and equipment that require reliable, replaceable movement. four material options let you match load, floor surface, and environment. The polyurethane variant is pictured to illustrate the gray wheel with an all-polymer housing.

Features

• Material options: resilient (black hard rubber), high modulus (black soft rubber), polyurethane (gray), and polymer housing (all polymer, no metal).
• Weight capacity: 800 lb per cart for resilient and high modulus variants; 1200 lb per cart for polyurethane and polymer variants.
• Post compatibility: fits 1" diameter hollow bottom posts.
• Construction: casters are sold individually; polymer housing offers corrosion resistance and straightforward cleaning.
• Dimensions: approximately 5" in overall height; each caster weighs about 3 lb.

Benefits

Choose the right stem caster to optimize performance for your workflow. The higher-load polyurethane and polymer options deliver robust durability for carts that repeatedly carry heavy equipment, while providing solid roll quality on durable floors. The resilient and high modulus variants offer dependable performance where balance between load and floor impact matters. With an all-polymer housing, these casters reduce metal exposure, helping prevent floor marking and simplifying maintenance in clinics, labs, warehouses, and industrial settings.

Who this is for: facility managers, maintenance teams, and shop-floor operators who need dependable, easily replaceable wheels that fit standard 1" stem posts. Use cases include janitorial carts, mail and supply carts, tool trolleys, and equipment carts that require consistent rolling performance and long service life. For environments prioritizing weight capacity and durability, the polyurethane or polymer variants are particularly well-suited; for cost-efficient, mid-range loads, the resilient or high modulus options offer strong value.
