Great Stability & Glide
Sof-Runner® completely eliminates shaking common to polyurethane wheels. High-tech one-piece "Tubearing" tube ball bearing is insert-molded right into the polypropylene hub! The bearing cannot come out - it's insert-molded right into the hub!
Resists Side Impact
Unlike conventional wheels, the Sof-Runner® wheel hub has been redesigned with a curved slope to give it improved resistance to side impact thrusts. Subsequently, Sof-Runner's new structural wheel hub "bounces back" and keeps running smoothly.
Smooth, Durable Roll
Sof-Runner® has re-invented the wheel with a tough new tire molded from cast polyurethane, which is well-known for its resilience and wear resistance. Sof-Runner®'s ability to absorb impact smooths out the "bumpy" roll normally associated with hard thermoplastic wheels. Very soft wheel tread creates a quiet ride. Lateral movement and high impact have no effect on wear, extending both caster and cart life - up to 5 times longer than normal.
Resulting from an intensive research program designed to improve the quality of our products, theTECH-SEAL® process has become state of the art in metal finishing where a zinc phosphate coating is applied on the whole surface of the product, followed by a chromic sealer, then a coating of cathodic primer. Designed to improve corrosion resistance (especially in difficult to reach areas and joints), the process concludes with a top-coating of polyester and teflon which ensures resistance to water, humidity, salt, and UV rays as well as extreme ambient temperatures.
