This USA made 8" x 2" performance X-tra Soft wheel swivel caster with 4" x 4.5" top plate and 3/4" kingpin provides best-in-class equipment/cargo and floor for your industrial application. What makes the 3/4" kingpin important? The kingpin holds the entire raceway section together and is a leading failure point of industrial casters (after the wheel), and this 3/4" kingpin provides a 40% longer life vs. the standard imports with a 5/8" kingpin. This X-tra Soft wheel, featuring sealed precision ball bearings, is a leading wheel choice for those looking for smooth, quiet, and floor protective mobility–and it even rejects debris, including metal shavings, screws, and nails. Traditional industry rubber and TPR wheels (that many will position as similar to X-tra Soft) will not do this, and will drag pallet nails and debris across your floor, ruining tape lines or paint. Providing shock absorption, ergonomic advantages, and durability, X-tra Soft wheels are versatile across indoor/outdoor applications and are resistant to water and most chemical and oils. This caster features a 1/4" thick steel construction, with legs welded for strength, RoHS compliant zinc plating for corrosion resistance, and a premium 3-year warranty. The caster rig and X-tra Soft rubber wheel are also manufactured in the United States, providing quality and supply chain dependability.
