Manufacturer of Industrial Wheels
Polyurethane on cast iron is the most versatile and cost effective industrial wheel on the market. Trew’s polyurethane tread is liquid cast and chemically bonded to a Class 30 solid web cast iron center. The tread is resistant to most chemicals, protects floors, is quiet, has great load bearing, wears like iron, and is non-marking and non-sparking. The wheels can be equipped with a variety of bearings including the easy rolling ball bearing setup. We offer a very large selection of sizes and bearing combinations. If what you need is not listed please consult the factory.

  • Made in USA
    All Trew wheels are made in the U.S.A.
  • Liquid Cast Tread
    Wheels are liquid cast polyurethane, chemically bonded to durable cast iron centers.
  • Solid Web Casting
    Most centers have a solid web design which affords greater strength and allows easier cleaning.
  • Unique Crown Tread
    Trew’s unique crown tread design with no-parting line affords optimum rollability and comes standard in most sizes with widths of 1 1/2”, 2”, 2 1/2”, and 3”. Please specify if flat tread is desired.
  • Retaining Washers
    All wheels with roller bearings are shipped standard with flat metal retaining washers. Tri-washers are available on 3/4” roller bearing wheels at no extra charge.
  • Keyways
    Most polyurethane wheels with iron centers can be supplied with a keyway and/or set screws as an option.
  • Capacities
    Capacities listed are based on the use of our standard 95A polyurethane tread. Other urethane compounds available including 70D extra hard that increases capacity substantially.
  • Grease Fittings
    Grease fittings are standard on wheels 5” diameter and larger.
  • Washer Seals
    Washer seals are available as an option.
  • Alternate Bore Sizes
    Non-standard bore sizes are available on most sizes.
  • Tapered Bearings
    All tapered roller bearing wheels come complete with seals and spacers.
  • Abrasion Resistance
    Polyurethane tired wheels have up to 5 or more times the abrasion resistance of rubber wheels.
  • Roll Easily
    Polyurethane wheels start and roll much more easily than rubber under heavy loads.
  • Non-Marking
    Polyurethane wheels are non-marking regardless of color.
  • Operating Temperature
    Operating temperature range for Trew’s standard polyurethane wheels is -20°F to 200°F intermittent, 0°F to 180°F Continuous. Special urethanes are available that are more suitable for higher/lower temperature applications.
  • Wet Conditions
    Trew offers special polyurethane treads for constant wet or moist conditions. Please consult the factory.
  • Non-Sparking
    Urethane treads are non-sparking and non-conductive.
  • Noise Reduction
    Also available with softer polyurethane treads which significantly reduce noise in most applications.
  • Cast Iron
    Trew cast iron has a minimum tensile strength of 30,000 PSI.
  • Constant Rotation
    Capacities are based on intermittent use. Constant rotation reduces capacities.
  • Bearing Lubrication
    Bearings require additional lubrication prior to use.
  • Chemical Resistance
    Polyurethane wheels are resistant to most chemicals, solvents, and detergents.
  • Increased Capacities
    Harder poly treads, available in all sizes, increase stated capacity substantially. Please consult the factory.
  • Ultra Thick Treads
    Ultra thick treads are available on all sizes. Thicker tread provides more cushioning and greater capacity in most applications.
  • Precision Ball Bearings
    All 1 1/2” to 3” wide wheels are available with sealed precision grade ball bearings and T-bushing set-up.
  • Three Tread Colors
    Three colors of polyurethane to choose from at no additional cost - green, red or blue. Green tread is our standard and is most readily available from stock. Other colors are available.
  • Metric Sizes
    Metric sized wheels are available.
  • Tensile Strength
    The tensile strength of our standard polyurethane is 7400 PSI.
  • Special Polyurethanes
    Choice of polyurethane hardness: 95A is standard and suitable for most applications; however, we offer a complete range of urethane types and hardnesses as options. (Non-standard compounds may extend delivery time.)
