4 Inch Caster Assemblies

Find 4-inch load wheels, steer wheels, and wheel assemblies for pallet jacks and material handling equipment. Our 4 Inch collection lets you shop directly by wheel diameter — useful for smaller-frame manual pallet jacks and light-duty equipment where 4-inch wheels are the OEM specification.

4-inch wheels are commonly used on light-duty manual pallet jacks and compact walkie equipment from Multiton, Uline, Dayton, and other standard-capacity brands. Wheels are available in polyurethane, nylon, and rubber materials to match your floor surface and load requirements.

4-inch wheel types available:

• 4" Polyurethane Load Wheels — smooth warehouse floors; low rolling resistance and floor protection
• 4" Nylon Load Wheels — rough surfaces and higher load capacity applications
• 4" Steer Wheels — front steer wheel replacements in standard 4-inch diameter
• 4" Wheel Assemblies — complete wheel and hub assemblies with bearings installed

How to select the right 4-inch wheel: Match by wheel width and hub bore in addition to diameter. Common 4-inch load wheel widths range from 1.25" to 2". Use the filters above to narrow by material and width
