These high temp casters are well suited for institutional and industrial applications rated up to 320 lbs. per caster. The series feature 3”, 4” & 5” dia. wheels with widths less than 2”. Each swivel caster rig has high temperature grease and the wheel materials and bearings are engineered to withstand oven-like temps.

For food processing, baking, or pharmaceutical environments or where floor protection is required, select casters with the Thermolast™ or Noiseless Ultratherm wheel types.

For more rugged applications that don’t require floor protection, select the Metal or Stainless wheel types.
