Engineered to dominate under pressure. The 48286/48220 RICH is not just any tapered roller bearing—it's a heavy-duty, high-performance component built to withstand intense radial and axial loads with unmatched stability. With its robust geometry and precise tolerances, this single row tapered roller bearing ensures smooth, controlled rotation even in the harshest mechanical environments.
Featuring a substantial 123.825 mm inner diameter, 182.562 mm outer diameter, and a total width of 39.688 mm, it’s designed for machines where reliability is non-negotiable. The inner ring width measures 38.1 mm, and the outer ring (C) comes in at 33.338 mm, striking the perfect balance between strength and operational efficiency. With a total weight of 3.401 kg, this bearing delivers serious performance without compromise.
Manufactured in China by RICH, this bearing features a separable cone and cup system, simplifying mounting, inspection, and replacement. Its adjustable axial clearance allows tailored performance tuning—making it the preferred choice for engineers and OEMs demanding rugged versatility and superior alignment in axles, gearboxes, industrial drives, and construction machinery.
