The NNCL 4844 CV is a double-row cylindrical roller bearing with a 220mm bore and 270mm outer diameter, built for combined loads. Made from durable 52100 chrome steel, it handles radial loads up to 85500 lbf and runs smoothly at 1000 RPM.
Its full-complement design (no cage) maximises roller count for higher load capacity, while the open structure allows flexible lubrication with grease or oil. The bearing operates in temperatures from -30°C to 110°C.
With a 50mm width and precise tolerances, it fits snugly in heavy-duty setups. The inner ring design and 4mm axial displacement tolerance help accommodate slight misalignments.
Ideal for industrial gearboxes or large machinery where high radial loads are common. Compliant with RoHS and REACH standards for safe use across regulated markets.
