These standard-duty casters cover the middle Hamilton capacity band for carts and tooling. Casters in this collection range from about 600 to 1,630 lb per caster. Wheel diameters run about 4 to 12 in with treads about 2 to 3 in. Most mounts use a 5-1/4 x 7-1/4 in top plate. Polyurethane (poly or urethane) on iron or aluminum cores is the common floor-safe tread. Phenolic builds are listed when you need a hard wheel on smooth concrete. Many titles in this band are spring-loaded plate casters for thresholds and uneven floors. Soft polyurethane is the better pick when the floor has chips or debris. Match the plate, overall height, and swivel or rigid style before you place the order. Capacities below are per caster unless a listing says set. Spring-loaded Forge Master series: AEZFFM spring loaded. Brand aisle: Hamilton casters.

  2. Mount: most Hamilton standard-duty casters use a 5-1/4 x 7-1/4 in top plate; 4-1/2 x 6-1/2 in and 4 x 4-1/2 in plates are listed too; check the bolt spacing on your frame against the plate size.
  3. Floor: on Hamilton standard-duty casters, polyurethane is kinder to tile and finished floors; phenolic rolls easier under heavy loads on smooth concrete.
