MetroMax Q Stem Casters — Polymer & Resilient Options for Humid and Chemical Environments

Introduction

MetroMax Q Stem Casters are corrosion-resistant wheels designed for MetroMax frames and carts. Ideal for humid and chemical environments, they come in two configurations: lightweight polymer casters with no exposed metal (up to 300 lb per caster) and resilient casters with metal hubs for heavier loads (up to 800 lb per caster).

Features

• Q Stem mounting: Designed for seamless fit and quick replacement on MetroMax frames.
• Material options: Polymer casters with no exposed metal parts for maximum corrosion resistance; resilient variants include metal hubs for higher strength.
• Load capacity: Standard polymer casters rated at 300 lb per caster; resilient (metal hub) casters rated up to 800 lb per caster.
• Wheel finish: Polyurethane finish to protect floors and reduce wear over time.
• Physical specs: Approximately 3 lb per caster; wheel width of 5 in.
• SKU & category: SKU: 5MPRX; Category: MetroMax; Product line: MetroMax Q Stem Casters.

Benefits

These casters deliver reliable performance in environments where metal exposure would be a liability. The polymer, no-metal design minimizes corrosion in humid and chemical settings, helping extend the life of carts and shelving. When you need to move heavier loads, the resilient version with a metal hub provides up to 800 lb capacity per caster, maintaining stability and smoother rolling. The polyurethane finish protects floors from scuffs and wear, making them suitable for frequent movement in labs, healthcare facilities, and industrial spaces. The Q Stem design ensures straightforward installation on MetroMax systems, enabling quick upgrades or replacements without tools-heavy downtime.

Who this is ideal for: facilities and teams using MetroMax frames in humid, chemical, or moisture-prone environments, needing either standard load handling or heavier-duty performance without sacrificing floor protection.

Tips for use: Match the caster configuration to your load requirements, ensure proper wheel alignment with the MetroMax Q Stem interface, and consider multiple casters across a cart or rack to distribute weight evenly for optimal stability.
