Double Row Full Complement Cylindrical Roller Bearings NNC 4838 CV

Double Row Full Complement Cylindrical Roller Bearings NNC 4838 CV

The NNC 4838 CV is a double row full complement cylindrical roller bearing with a 190mm bore and 240mm outer diameter, crafted from durable 52100 chrome steel. It handles combined loads up to 80550 lbf and operates smoothly at speeds up to 1000 RPM.

Its full complement design (no cage) maximises load capacity, while the open seal allows easy lubrication with grease or oil. The bearing performs reliably in temperatures from -30°C to 110°C.

This model is interchangeable with SKF bearings, making it a practical choice for replacements. Ideal for heavy-duty applications like industrial gearboxes or large machinery where high radial loads are common.

Weighing 5.65kg, it’s robust yet manageable for its size. Compliant with RoHS and REACH standards for safe use.
