QUADRANT 21001292N080050000 is a polyurethane rod, often referred to as a urethane pin. It is used in a variety of applications, most commonly as a pivot point in an articulated structure, such as an automated door or conveyor, or as an axle or rod in machines or other machinery. It often features a small hole in the center of the pin to allow for rotation or other short-distance movements. The urethane material is durable, resists abrasion and corrosion, and is ideal for use in parts exposed to moisture, dust, or high friction.
