S30 Series

This collection holds S30 Series casters with polyurethane, rubber and nylon 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, rigid, and brake models. 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. Nylon rolls easily, resists water and many chemicals, and is hard, so it is loud on rough floors. Softer polyurethane or soft rubber or TPR tread is the better pick when the floor has chips or grit. Match plate size, bolt pattern, and overall height before you order. Choose swivel casters when the cart must turn in place and rigid casters for straight travel. Polyurethane aisle: polyurethane casters. Wheel hub: replacement wheels.

Choosing Durastar S30 series casters

  1. Load: divide the loaded weight by three for a four-caster cart [S2]. Among Durastar S30 series casters, a 1,200 lb caster then suits about 3,600 lb, and the strongest at 1,250 lb about 3,750 lb.
  2. Mount: most Durastar S30 series casters use a 4 x 4-1/2 in top plate; measure bolt hole centers on the old plate and compare.
  3. Floor: on Durastar S30 series casters, polyurethane and rubber are kinder to tile and finished floors; polyolefin, nylon and phenolic roll easier under heavy loads on smooth concrete.
  4. Rig: swivel and rigid Durastar S30 series casters are listed.
