Industrial Casters. Engineered for Spec.
Hamilton uses forged steel rigs (not stamped) for shock load resistance, sealed precision tapered roller bearings (not loose ball) for chemical-environment service life, and bonded poly + cast iron + forged steel wheel options that handle continuous-duty industrial service. Aerospace ground support equipment, foundry transfer carts, military depot loaders, and Tier-1 OEM assembly fixtures all spec Hamilton because the failure modes are predictable and the rebuild parts are stocked for decades.
S-series = Swivel casters. R-series = Rigid casters. W-series = Wheels only (replacement). H-series = Specialty / heavy-duty configurations. Within each series, the next number indicates the wheel diameter (e.g., S-7012-PRB is a swivel caster with 12" wheel, pneumatic, roller bearing). The trailing letters describe wheel material and bearing type.
Hamilton Caster builds most products to order in their Hamilton, Ohio plant — they don't carry massive finished-goods inventory like volume distributors. The trade-off: every Hamilton caster comes with traceable lot/serial info, custom configurations are available (special wheel durometers, conductive compounds, food-grade options), and rebuild parts are always available. For most industrial buyers, the 2-3 week lead is acceptable because the caster lasts 5-10x longer than commodity alternatives.
Hamilton W-720, W-820, W-920 series cross to RWM Aluma-Tuf and Albion 16-Series for forged steel wheels. Hamilton S-SEC kingpinless casters cross to Albion's 110-series. Hamilton Cush-N-Aire pneumatic series crosses to RWM Pneumatic. CasterHQ engineering can cross any Hamilton part number — submit RFQ with the Hamilton model and we'll match to in-stock equivalents or sourced Hamilton.
For aerospace ground support and military depot equipment, spec Hamilton SEC kingpinless with sealed precision tapered roller bearings — they're the only configuration rated for continuous towline service at 5+ mph with no service interval for 10+ years. The 12-15% premium over standard kingpinless pays back inside year one in eliminated maintenance.
Custom durometer, hub material, plate spec, or non-standard size — engineering team turns RFQs same day.
For continuous-duty industrial service: yes. Hamilton typically lasts 5-10x longer than commodity casters under same conditions due to forged steel construction + sealed precision bearings. Total cost of ownership over 5 years is significantly lower despite the 2-3 week lead. For one-time replacement on light/medium duty equipment, faster brands (Albion, Colson) are often the better trade.
Yes — submit RFQ. Hamilton offers conductive polyurethane (10^4 to 10^6 ohm surface resistance) for ESD-sensitive areas, FDA-compliant compounds for food/pharma, and clean-room-rated sealed bearings. These are typically 4-6 week lead and require engineering specification of the exact conductivity / cleanliness target.
Provide the Hamilton caster part number (S-XXXX or R-XXXX format) — we cross to the matching W-series wheel. If you don't have the original part number, photograph the wheel side-by-side with a tape measure showing diameter + tread width + bore, plus the rig stamp if visible. Our engineering team crosses to the exact W-series replacement.
Standard 1-year manufacturer warranty against defects. Premium series (SEC kingpinless, Cush-N-Aire pneumatic) carry 2-year warranty when paired with sealed precision bearings. All warranty claims handled through Hamilton's authorized distributor network — CasterHQ processes warranty replacements directly with Hamilton.
Yes — Hamilton's Hamilton, OH plant builds custom configurations regularly. Common custom specs: non-standard plate sizes, specific durometer polyurethane, conductive wheel compounds, color-coded ESD wheels, food-grade FDA wheels, marine-grade stainless rigs. Custom lead time is typically 4-6 weeks. Submit RFQ with your spec sheet to engineering.
