Product Details
About This Wheel - 31MH40-03
Use this 4-inch Performa wheel where the cart should run silent and never need service, the mid-size Delrin-bearing wheel that rolls an office, library, or AV cart for years without a drop of grease.
The Delrin bearing is the point here: it is sealed-quiet and maintenance-free, so a cart that lives in a public or quiet space never squeals or needs attention, and the 4-inch diameter keeps the deck low and clears a cord or sill. The soft Colson Performa rubber on a polypropylene core stays hushed on carpet tile and hard floor alike and leaves no marks where appearance counts.
Ideal applications
- Office, library, and reading-room carts that must stay silent
- AV and media carts moved between quiet spaces
- Public-area carts where no maintenance is the goal
Skip the soft rubber if the cart carries heavy concentrated loads; it flattens under sustained weight, so a HI-TECH polyurethane wheel takes that load and stays round.
Pairs with: the matching 4-inch swivel and rigid forks for a quiet four-corner cart.
Wrong fit? Want a smoother roll under heavier daily use? See the ball-bearing 31MB40 and HI-TECH poly.
Also in this family: the ball-bearing 31MB40, or the full Colson collection.
