Koyo Bearing METRIC TAPERED ROLLER BEARING SETS KOY 30208-JR
Tapered roller bearing are designed such that cup, cone and rollers have tapered surfaces whose apexes converge at a common point on the bearing axis. Along with metric series bearing, inch series bearing are also available. This type of bearing is suitable for applications that involve heavy or impact loading.

NCS-4424 ) is an inch-series, heavy-duty machined needle roller bearing without an inner ring.
• Shaft Diameter (Under Roller / Bore \(F_{w}\)): 2-3/4 inches (2.7500 in / 69.85 mm)
• Note: In imperial needle bearing nomenclature, the first digit "44" denotes the bore size in sixteenths of an inch (44/16" = 2.75").
• Outside Diameter (D): 3-1/2 inches (3.5000 in / 88.90 mm)
• Note: The second digit "56" in standard cross-references indicates the outer diameter in sixteenths of an inch (56/16" = 3.5").
• Overall Width (C or B): 1-1/2 inches (1.5000 in / 38.10 mm)
• Note: The final digit "24" indicates the outer ring width in sixteenths of an inch (24/16" = 1.5").
• Dynamic Load Rating (\(C_{r}\)): 22,300 lbf (99,200 N)
• Static Load Rating (\(C_{0r}\)): 45,000 lbf (200,000 N)
• Limiting Speed (Oil): 6,500 RPM
