Track rollers, which are also referred to as idler rollers, are motion transmission components designed to work with all varieties of tracks. They see use in conveyor systems, cam drives, and a wide range of similar material handling systems. Among its many applications, track rollers can be found in robotic welders, assembly and paint line conveying systems, automated storage and retrieval systems, and fracking equipment. Regardless of the material or machine, these components play a critical role in track and rail operations. When selected, employed and maintained properly, they facilitate system operations, allowing for greater speed and efficiency.
From automotive assembly, food and beverage production and metal processing to pharmaceutical, pulp and paper, shipbuilding and wood products – there are many industries employing track rollers. Track rollers are available with outer ring running surfaces or cylindrical (or flat) outer ring running surfaces. While the ideal variety of track roller varies depending on intended use and application, the outer ring running surface is widely considered the gold standard.
