Choosing 50 mm office chair casters

Load: plan on three casters carrying a four-caster cart [S2]; at 80 lb each, a common rating here, that is about 240 lb, and the 90 lb top rating covers about 270 lb.
Stem: the most common stem on 50 mm office chair casters is 7/16 x 7/8 in; 2 x 3/4 in also appear; check the old stem with calipers before ordering.
Floor: on 50 mm office chair casters, polyurethane, rubber and pneumatic are kinder to tile and finished floors; nylon and polyolefin roll easier under heavy loads on smooth concrete.
Rig: swivel 50 mm office chair casters are listed, with side lock brake options.
