Choosing zinc plated casters on a 2-3/8 x 3-5/8 in plate

Load: divide the loaded weight by three for a four-caster cart [S2]; at 350 lb each, zinc plated casters on a 2-3/8 x 3-5/8 in plate suit a loaded cart of about 1,050 lb.
Mount: most zinc plated casters on a 2-3/8 x 3-5/8 in plate use a 2-3/8 x 3-5/8 in top plate; measure bolt hole centers on the old plate and compare.
Floor: on zinc plated casters on a 2-3/8 x 3-5/8 in plate, nylon suits smooth concrete and heavy loads, but is loud and hard on tile and wood.
Rig: swivel and rigid zinc plated casters on a 2-3/8 x 3-5/8 in plate are listed, with total lock brake options.
Heat: among zinc plated casters on a 2-3/8 x 3-5/8 in plate, the highest listed range is -45°F to 475°F (550°F intermittent) on nylon; check the temperature field on each listing before oven or hot-room use.
