At Hamilton, we are all in on engineering challenges. So when Service Caster tapped us to solve a laundry service dilemma, we didn’t hesitate to get our hands dirty.
The ask: Spec power-driven wheels for a drive application used in the laundry service’s pre-dryers. The pre-dryers, which spun towels at high speeds to drive out excess water and reduce time in the heated dryer stage, used wheels made from Nylon 6 material and employed keyways in the wheel hubs. Over time, the nylon didn’t hold up, the keyways elongated and the wheels failed. No bueno.
Enter Hamilton Nylast Wheels to the rescue. Why Nylast? As a popular alternative to steel, they’re made from solid cast high performance nylon and provide superior impact strength and resilience compared to conventional injection-molded nylon wheels (in other words, they’re much stronger than Nylon 6). Specially formulated with finely divided particles of molybdenum disulphide (MoS2), these wheel warriors enhance load bearing capability while maintaining the impact-defiant properties of nylon. Plus they’re moisture- and chemical-resistant, making them ideal for applications that demand sanitary conditions.
To make the wheels even tougher, we carved into them and inserted a special stainless steel core with the keyway to address the elongation. Nylast plus stainless steel equals pure driving power.
Fluff and fold, baby. Fluff and fold.
