Double Row Full Complement Cylindrical Roller Bearings NNCL 4976 CV

Double Row Full Complement Cylindrical Roller Bearings NNCL 4976 CV

The NNCL 4976 CV is a double row full complement cylindrical roller bearing, measuring 380mm by 520mm by 140mm. Made from durable 52100 chrome steel, it handles combined loads with a dynamic radial load capacity of 535500 lbf.

Its full complement design (no cage) allows for higher load capacity and smooth operation at speeds up to 1000 RPM. The open seal type makes lubrication with grease or oil straightforward.

This bearing can withstand axial displacement up to 7mm and operates in temperatures from -30°C to 110°C. It’s interchangeable with SKF bearings, offering a reliable option for replacements.

Ideal for heavy-duty applications like industrial gearboxes or large machinery where high radial loads are common. Compliant with RoHS and REACH standards for safe use.
