Rigid Casters™

STR4100 Series Caster™

Designed primarily as a robust rigid caster for heavy duty material handling carts, trucks and rigging equipment, the STR4100 Series excels where others fail. With a solid steel cast housing, no fasteners to break, and hardened steel bearing race, it’s aisles ahead of the competition.

Heavy Duty Steel Construction - Solid casting without welds and heavy duty kingpin-less swivel mechanism.

Convenient Greasability - Greasing moving parts is critical to prolonging work-life. With conveniently located grease fittings, basic maintenance is even easier.

Longer Wheel Work-Life from a Large Load Wheel - by using a large 6” OD wheel with the toughest polyurethane compounds available, and a 3” wide cross section provides extreme durability and optimal load capacity.

Consistently Smooth Swivel - specially designed with a hardened steel bearing race uses rubber O-rings to lock out moisture & debris, and lock in grease.

Sealed Bearings & String Guards - preventing debris from binding up the load wheels while maintaining internal lubrication.

Zero Fasteners - factory assembled with no fasteners to eliminate the burden of nut & bolt weaknesses.

Standard Features
• Rust Proof Zinc Plating
• Greasable Wheel Axle
• 8” Standard Height
• Available for: STR4163, STR4164
