Why Hamilton soft wheels work hard

Thursday, May 28, 2020

Building the toughest casters and wheels on the planet is macho business. Sometimes, we need to take a break from all the swagger and testosterone to get in touch with our softer side. After all, there are plenty of delicate goods in the manufacturing world that need some extra TLC. Good thing Hamilton’s got a range of cushy wheels that protect as much as they perform. So pull on your comfy sweats, sit back and take a ride with us into the world of soft treads and quiet rides.

Why soft treads?

First, let’s look at the pros and cons of “soft” treads, meaning treads with a durometer of 75 or lower on the Shore A scale.


  • Absorbs shock to cushion your ride
  • Minimizes noise for quiet operation
  • Non-marking rubber is easy on floors
  • Better traction and grip on slippery floors
  • Rolls/climbs easier over rough terrain and obstacles like cords or uneven floor expansion joints


  • Can compress under heavy loads
  • Tends to build up heat
  • Typically lower payload capacity
