Allen-Bradley 141K099G01 Belt Tensioner Assembly Roller

141K099G01 Belt Tensioner Assembly (OEM/unbranded) is an adjustable bolt-on tensioner for belt-driven power transmission in industrial equipment, designed to keep belts at the correct tension and aligned to reduce slip and wear. It uses a steel bearing assembly with a sealed ball bearing and a smooth, free-spinning roller of 1.496 inches in diameter and an overall height of 3.93 inches. The bolt-on mounting style makes installation straightforward on conveyors, packaging equipment, manufacturing machinery, HVAC units, and other material-handling systems where consistent belt performance matters. The unit is finished for indoor industrial environments to resist corrosion, and maintenance typically involves periodic inspection and bearing replacement as needed. For reference, common replacements include Gates DriveAlign Belt Tensioner Assembly, Dayco Automatic Belt Tensioner Assembly, and Continental Elite Belt Tensioner Assembly.
