SKF Roller Bearing, Needle Bearing Type, 19mm ID, 27mm OD - NK19/20TN
Need a compact bearing that's capable of supporting heavy radial loads? This needle roller bearing from SKF has a 19mm inside diameter and achieves a dynamic load rating of 16.5kN and static load rating of 25.5kN, making it ideal for heavy-duty use. The cylindrical rollers are made from durable carbon chromium steel, which resists corrosion so is suitable for use in humid workplaces. The outer ring has an annular groove to securely retain a snap ring, while flanges are on hand to make axial positioning easier.
Reinforced nylon 66 cage minimises friction and boosts lubricant circulation
Maximum oiled speed of 20,000r/min for use with very high-speed applications
Hole in the outer ring makes lubrication easy

Can this roller bearing be fitted directly to the shaft?
Yes, one of the biggest advantages of needle roller bearings is that they can use the mating surface as the inner raceway if the shaft is hardened and ground. Because this bearing doesnt need a separate inner ring, it can be used with a larger shaft diameter.
