Capacities vary widely by style: small stem casters often list around 100 lb per caster, appliance roller bases commonly state about 330 lb capacity for the base, and heavy-duty top-plate casters can be rated up to about 1,000 lb per caster. Always confirm the manufacturer’s load rating for the exact product and whether the rating is per caster or for a complete base.
Small cabinet casters commonly use 2-inch diameter wheels with overall caster heights around 4.0–4.25 inches. Larger, heavy-duty options often use bigger wheels such as 6"×2" (diameter × width) or similar larger wheel dimensions.
Common options include toe brakes on stem casters, side-mounted brakes on swivel casters, and fully lockable 360° swivel casters that secure the cabinet in place.
You’ll find push-in stem casters that require no tools, top-plate casters that bolt on using four mounting holes, and adjustable appliance bases that expand to fit appliance widths and include integrated rollers.
Common package sizes include 4‑packs of casters and 2‑piece appliance roller sets. Many caster listings show a package quantity of four, while appliance rollers are often sold in pairs.
Heavier-duty rollers commonly use carbon steel or galvanized steel for frames, plates, and brackets, paired with polyurethane or rubber wheel treads for durability and floor protection.
