- 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.
Most polyurethane wheels with iron centers can be supplied with a keyway and/or set screws as an option.
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.
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.
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.)
