TPY Series - Tapered Roller Bearing

The TPY Series polyurethane on iron wheel with tapered roller bearings is a heavy-duty upgrade to the standard PY wheel, built for demanding industrial carts and equipment. It features the same proven 95A polyurethane tread bonded to an iron core and the same 2-inch tread width, but comes standard with tapered roller bearings instead of needle bearings. That matters because tapered bearings handle both radial and thrust loads, making them better for side-loading, tight turns, and repeated impact on loaded carts. The wider tread also spreads weight more effectively, helping reduce wear while improving performance on smooth concrete floors. Compared to standard rubber wheels, this polyurethane tread rolls easier and offers better resistance to oil, grease, abrasion, cutting, and shop-floor damage, making it a strong choice for industrial environments.
Common uses for the TPY Series tapered roller bearing wheel include die carts, mold transport, welding tables, fabrication fixtures, machine bases, equipment dollies, assembly line carts, maintenance carts, print and packaging equipment, metal service centers, aerospace tooling carts, automotive parts carts, and electrical or transformer shops. It performs best in controlled conditions on flat concrete at walking speed, though rough floors, debris, shock loading, and higher speeds will reduce actual capacity. Polyurethane can handle static loads up to 65% of rated capacity, but it is not ideal for long-term standing loads because flat spotting can develop over time. With a working temperature range of -20°F to 180°F, the TPY wheel is well suited for many shop applications, though sustained high heat, chemical exposure, or repeated heavy impact can shorten tread life.
