34 Series

This collection holds 34 Series casters with polyurethane, rubber and metal wheels, built for shop carts, equipment, and material handling carts that move heavier loads. Casters in this collection range from 300 to 2,000 lb per caster. Wheels in this category range from 4 up to 8 inches in diameter with a 2 in tread width. The collection includes swivel and rigid models. Flanged and V groove track wheels ride on rail or angle iron track for straight line travel. Polyurethane (poly or urethane) treads are quiet, floor safe, and resist water and many chemicals. Rubber wheels are quiet, cushion the load, and protect floors. Metal wheels roll with low effort and handle debris and heat. They are loud and can mark finished floors. Choose swivel casters when the cart must turn in place and rigid casters for straight travel. Read the listing for the exact wheel size, overall height, and mount shown. Polyurethane aisle: polyurethane casters. Wheel hub: replacement wheels.

Choosing Durastar 34 Series casters

Load: plan on three casters carrying a four-caster cart [S2]; at 1,200 lb each, a common rating here, that is about 3,600 lb, and the 2,000 lb top rating covers about 6,000 lb.
Mount: most Durastar 34 Series casters use a 4 x 4-1/2 in top plate; measure bolt hole centers on the old plate and compare.
Floor: on Durastar 34 Series casters, polyurethane and rubber are kinder to tile and finished floors; nylon, ductile iron, semi-steel, phenolic and polyolefin roll easier under heavy loads on smooth concrete.
Rig: rigid and swivel Durastar 34 Series casters are listed.
Heat: among Durastar 34 Series casters, the highest listed range is -45°F to 800°F on ductile iron; check the temperature field on each listing before oven or hot-room use.
