These shock-absorbing casters are Hamilton spring loaded builds that cushion carts and fixtures on uneven floors. Casters in this collection range from about 450 to 2,775 lb per caster. The legacy handle says 10,000 lb. Active titles top out at 2,775 lb. Soft polyurethane (poly or urethane) and other resilient treads ride quieter than hard iron on broken concrete. Soft polyurethane on aluminum (~85 Shore A) or TPR is the better pick when the floor has chips or debris. Most mounts are top plates. Pronto stock ships faster. Custom builds take longer lead time. Match spring capacity and overall height before you order. Confirm the load rating printed on the title before you place your order today. Keep the load on the rating for that SKU and do not exceed it in service. Capacities below are per caster unless a listing says set. Spring sibling: spring loaded AEZFFM casters. Aerospace spring aisle: aerospace casters.

Shock-absorbing questions

Why does the URL say 10,000 lb?

The handle is legacy. Verified active titles top out at 2,775 lb per caster. H1 and SEO follow the true max.

Same as aerospace or AEZFFM spring hubs?

High overlap. This page keeps shock-absorbing language; AEZFFM and aerospace siblings share the same 2,775 lb verified ceiling.
