Colson ThermoTech Stainless Casters with Teflon Bearings

These Colson ThermoTech stainless casters use Teflon bearings for washdown and high-heat service. Casters in this collection range from about 250 to 300 lb per caster. Wheel sizes are 4 and 5 x 1-1/4 in on a 2-1/2 x 3-5/8 in top plate. ThermoTech wheels cover most titles at 250 lb; one Performa rubber listing is rated 300 lb. Stainless frames suit wet and corrosive kitchens. Total lock and brake options are listed on several SKUs. Match plate size and brake style before you place your order today. Read the listing for the exact wheel and lock shown. Confirm the rating on the listing before you buy. Keep the load on the rating printed for that SKU. Verify the SKU matches your old unit. Capacities below are per caster unless a listing says set. Full Colson aisle: Colson casters. Food service aisle: food service casters.

What ThermoTech is

ThermoTech is Colson's high-heat rubber tread molded on an aluminum core [S2]. Ordinary rubber and polyurethane are usually rated near 160 to 180°F. ThermoTech is rated to 490°F continuous and about 525°F for short exposure, with a 75 Shore A tread that stays quiet and does not mark floors. Colson mounts it in the 2 Series polished 304 stainless rig [S2].

Why a Teflon bearing

A Teflon (PTFE) bearing is what Colson codes as .613 on these part numbers (for example 2.04456.613 and 2.05456.613). It handles the heat range of the ThermoTech tread better than a standard Delrin bearing in this series. The wheel tread is still rubber ThermoTech, not solid PTFE.

Teflon bearing caster questions

Is the wheel made of Teflon?

No. On these Colson part numbers, Teflon is the wheel bearing. The tread is ThermoTech high-heat rubber (or Performa on the one 300 lb listing).

What temperature can ThermoTech take?

Colson rates ThermoTech -45 to 490°F continuous and about 525°F intermittent [S2]. Confirm grease and brake limits on the listing for your oven or washdown cycle.

What plate size is this?

2-1/2 x 3-5/8 in top plate (bolt pattern about 1-3/4 x 2-13/16 to 3-1/16 in) on the Colson 2 Series stainless units here.
