The NNC 4920 CV is a double-row cylindrical roller bearing with a 100mm bore and 140mm outer diameter, crafted from tough 52100 chrome steel. It supports heavy radial loads up to 47025 lbf and handles combined loads with ease.
Its full complement design (no cage) maximises roller count for higher load capacity, while the open seal allows simple lubrication with grease or oil. The bearing operates smoothly at speeds up to 3000 RPM.
With a compact width of 40mm, it fits well in tight spaces. The chrome steel rollers ensure durability in temperatures from -30°C to 110°C.
Ideal for industrial gearboxes or heavy machinery where space and load capacity matter. Weighing 1.94kg, it’s robust yet manageable. Compliant with RoHS and REACH standards.
Interchangeable with SKF bearings for easy replacement. The 5mm lubrication groove and 3.5mm holes simplify maintenance. Chamfered edges (1.1mm) help with smooth installation.
