Double Row Full Complement Cylindrical Roller Bearings NNCF 4912 CV

Double Row Full Complement Cylindrical Roller Bearings NNCF 4912 CV

The NNCF 4912 CV is a double-row cylindrical roller bearing with a 60mm bore and 85mm outer diameter, crafted from durable 52100 chrome steel. It supports combined loads, handling up to 17572 lbf dynamically and 30825 lbf statically.

Its full-complement design (no cage) maximises roller count for higher load capacity, while the open seal allows easy lubrication with grease or oil. The bearing operates smoothly at speeds up to 4000 RPM.

With a compact 25mm width, it fits well in tight spaces. The 1mm chamfers ensure easy installation, and it withstands temperatures from -30°C to 110°C.

Ideal for heavy-duty applications like gearboxes or industrial machinery where space and load capacity are key. Compliant with RoHS and REACH standards for safe use.
