NN Series Double Row Cylindrical Roller Bearings
Double-Row Cylindrical Roller Bearings: Design, Advantages, and Applications
Double-row cylindrical roller bearings feature a compact design, high load-carrying capacity, and excellent rigidity. With these performance advantages, they are widely used in demanding industrial applications, including:
1.Machine tool spindles and grinding machines
2.Rolling mill equipment
3.Plastic processing machinery and calenders
4.Large industrial gearboxes
Features
Cylindrical and Tapered Bore Designs (NN Series)
NN series double-row cylindrical roller bearings are available with both cylindrical and tapered bore designs. Bearings with a tapered bore are commonly supplied to enable precise adjustment during installation.
By controlling the mounting position on the tapered shaft, the bearing can achieve the required radial internal clearance or preload, improving spindle rotational accuracy, rigidity, and overall operating performance.
