Phenolic Wheels

These phenolic wheels suit heavy warehouse carts, toolboxes, and tool carts that need a hard tread with steel-like strength and less floor chip than steel. Wheels in this collection range from about 300 to 3,500 lb per wheel. Wheels in this category range from about 3 up to 12 in diameter, including 10 x 3 and 12 x 3 high-load titles. Phenolic is built for dry heat. It is not a good pick around standing water or washdown. Regular phenolic is not suited for bakery racks. For bakery ovens, prefer green epoxy oven rack wheels, or a true high-temp phenolic listing if the SKU states that. Soft polyurethane on aluminum (~85 Shore A) or TPR is the better pick when the floor has chips or grit. Match bore and hub width to the old wheel before you order. Capacities below are per wheel as labeled. Moist or washdown heat aisle: high temp glass filled nylon wheels. Bakery oven aisle: green epoxy oven rack wheels.

Acorn's selection guide gives a similar -65 to 250°F range for standard phenolic [S2]. Above 250°F, step to the hi-temp phenolic or glass-filled nylon rows above.

Where phenolic works, and where it does not

  • Works: heavy carts on smooth concrete, die and parts carts, bakery and food racks near ovens, and areas with oil and grease. Hamilton lists phenolic as a low-cost way to carry heavy loads without damaging floors in intermittent service, and notes it is non-marking and resists oil, grease and common solvents [S3].
  • Avoid: wet floors and washdown. Colson does not recommend phenolic where moisture is present [S4]. Use nylon or polyolefin there.
  • Avoid: rough floors, floor plates and dropped loads. A hard resin wheel can chip or crack under shock.
  • Avoid: continuous use at high speed. Hamilton frames phenolic for intermittent service [S3].

Choosing a phenolic wheel

  1. Pick by temperature first: 250°F standard, 475°F hi-temp phenolic, 550°F glass-filled nylon.
  2. Then pick width for load. At 6 in, going from 2 in to 3 in wide lifts the rating from 1,200 to 2,000 lb.
  3. Match the bore and bearing. Several listings are sold by bore size (3/8, 1/2, 3/4 in) with roller bearings.

Phenolic wheel questions

How hot can phenolic wheels get?

Standard phenolic on this page is rated -50 to 250°F. Hi-temp phenolic is rated to 475°F, and the 2 in wide glass-filled nylon wheels to 550°F.

Are phenolic wheels OK in washdown areas?

Not a good fit. Colson does not recommend phenolic where moisture is present. Nylon or polyolefin handles water better.

Do phenolic wheels mark floors?

They are non-marking. They are hard, though, so debris under the wheel can scratch soft floors.

What is the strongest phenolic wheel you carry?

The 12 x 3 in phenolic wheel, rated 3,500 lb.
