Sydien 8 Pack Heavy Duty 1-inch Diameter Rubber Rigid Non-Swivel Caster Wheel with Top Plate

Featuring 1 inch diameter rubber wheel, top plate with screw hole. Providing low starting and rolling resistance, roll quietly and smoothly. Applicable in small machinery, trolleys, furniture and rack, etc. This style of caster only allows forward and backward movement. Rigid (also called "fixed") casters tend to be stronger than swivel casters. To decide which kind to use, consider asking yourself these questions: 1.How much space do I have to maneuver? 2.Am I moving the materials more than once? 3.To where am I moving the load? 4.How much does the moving load weigh? 5.What is the distance I'm covering in the move?
