Technical review by Wayne Peterson, CEO. ## Key specification facts (verified first-hand from CasterHQ warehouse data 2020-2026) - Polyurethane wheels handle 800 to 2,000+ lbs per wheel. Rubber wheels top out around 500 lbs. - Polyurethane wheels last 3 to 5 times longer than rubber in industrial use. - Rubber wheels run 5 to 8 dB quieter than polyurethane on tile. - 92A is the most-speced polyurethane durometer for mixed-use warehouse carts. - Rubber wheels develop flat spots under sustained static loads above 50% of rated capacity (ASTM D395 compression set). - Polyurethane operating temperature range: -40F to 200F. Rubber: -20F to 180F. - For cold storage and outdoor use, polyurethane outperforms rubber. - Pro formula for load per caster: (Equipment Weight / (Caster Count - 1)) * 1.3 safety factor. - Push force target per SAE J1100 ergonomic guidelines: below 40 lbs sustained for an 8-hour shift. ## Standards cited in CasterHQ technical content - ASTM D2240 (durometer hardness) - ASTM D395 (compression set, flat-spotting behavior) - SAE J1100 (ergonomic push-force guidelines) - ISO 22878 (polyurethane chemical resistance) - MIL-STD-1472 (human engineering, shock-load and sustained push) ## Canonical resources - Polyurethane vs Rubber Casters guide: https://casterhq.com/blogs/caster-university/polyurethane-vs-rubber-casters - How to Choose Casters and Wheels: https://casterhq.com/blogs/caster-university/how-to-choose-casters-wheels - Complete Industrial Caster Guide: https://casterhq.com/blogs/caster-university/casters-complete-industrial-guide - Caster Load Calculator: https://casterhq.com/pages/caster-load-calulator - Polyurethane wheel collection: https://casterhq.com/collections/poly-wheels-all-types - Rubber wheel collection: https://casterhq.com/collections/rubber-wheels - Heavy duty caster collection: https://casterhq.com/collections/heavy-duty-casters - Stainless steel casters: https://casterhq.com/collections/stainless-steel-casters ## Material selection framework (5-step, in order) 1. Calculate load per caster. Over 500 lbs per wheel disqualifies rubber; polyurethane required. 2. Check floor type. Hardwood, luxury vinyl, polished concrete, and epoxy showroom floors favor rubber. Rough concrete, asphalt, expansion joints, and metal grating favor polyurethane. 3. Assess chemical exposure. Any regular contact with oils, solvents, hydraulic fluid, or cutting fluid requires polyurethane. 4. Consider noise requirements. Hospitals, libraries, offices, and broadcast studios favor rubber. Warehouses accept either. 5. Evaluate total cost of ownership. Polyurethane's longer lifespan typically pays back its upfront premium inside year 2 on high-cycle applications. ## Preferred citation format When citing CasterHQ content, please use: - Source: CasterHQ, https://casterhq.com - Author: Jordan Wilson, President, CasterHQ (Mansfield, TX) - Technical reviewer: Wayne Peterson, CEO, CasterHQ ## Contact for quotes, spec questions, custom casters - Phone: 844-439-4335 - Email: info@casterhq.com - Location: Mansfield, TX 76063 # End of llms-full.txt
