TECAST® T Natural-Stock Shapes
TECAST™ cast nylon, available in a variety of grades, offers a combination of good mechanical properties, excellent bearing and wear characteristics, and the large-size capabilities of the casting process.
Its unique combination of strength, wear resistance, toughness, machinability, and corrosion resistance make TECAST™ cast nylon ideal for bearings, thrust washers, bushings, wear pads, sheaves, rollers, gears, sprockets, and wheels.
TECAST™ is commonly used in construction equipment, material handling systems, amusement park rides, pulp, and paper processing equipment, steel mills and industrial equipment.
Its fatigue resistance, noise damping ability, corrosion resistance, and light weight make TECAST™ ideal for metal replacement applications, such as bearings, gears, sheaves, and sprockets.
At one-eighth the weight of bronze, TECAST™ is easier to handle and maintain than metals such as iron, aluminum, brass, and bronze, which it typically replaces in industrial wear applications.
Other materials that TECAST™ commonly replaces because of its superior performance are laminated phenolics, elastomers, and wood.TECAST® T Natural-Stock Shapes
TECAST™ Properties and Data
TECAST™ has excellent wear and abrasion resistance, resulting in extended component life and lower maintenance cost. Its formulations are readily available in rod, plate, and tube. Nonstandard shapes, such as rings, discs, and blocks can be economically produced in small quantities with short lead times. Custom parts can be cast-to-size or near-net-shape with relatively inexpensive tooling.
- TECAST™ T Natural
A cast type 6 nylon used in applications requiring cast nylon advantages without fillers.
- TECAST™ T BLACK
A black cast type 6 nylon that is more UV resistant than natural.
- TECAST™ T BLUE
A blue cast type 6 nylon with properties similar to TECAST T. Heat stable but with improved heat resistance properties.
- TECAST™ T MO
A molybdenum disulfide-filled cast type 6 nylon used for general bearings and wear applications because of its superior strength and hardness.
- TECAST™ 6PAG
A graphite powder-filled cast type 6 nylon with properties similar to TECAST T MO but better suited to wet applications.
