Cast Iron Swivel Caster 4" x 2" - 700 lb

This caster is rated from -45F to 800F. The cast iron wheel and steel bearings maintain their load capacity and structural integrity across this full temperature range. This makes it suitable for powder coating oven carts and other equipment that passes through high-temperature environments.

The 700 lb model uses precision ball bearings with a zerk fitting for periodic greasing. The 1,102 lb model uses steel roller bearings with sealed dust covers. The 700 lb version is better for high-temperature oven use. The 1,102 lb version handles heavier loads on room-temperature equipment.

Grease the zerk fitting every 3-6 months under normal shop use. For oven cart applications where the caster is repeatedly heated, grease more frequently using high-temperature grease rated above your cure temperature. A few pumps from a standard grease gun through the zerk is sufficient.

Yes. The -45F to 800F temperature rating covers standard powder coating cure temperatures of 350-450F. Cast iron wheels will not melt, deform, or outgas at these temperatures like rubber or polyurethane wheels would. Use high-temperature grease in the zerk fitting for oven applications.

The Cast Iron/Steel Swivel Caster 4" x 2" with 700 lb capacity is priced at $18.80 (SKU CST-MA-4X2-S). It ships in stock from Creative Coating Solutions. Includes precision ball bearings, zerk fitting, and cast iron wheel rated to 800F.
