Product detailed description
The NN 3034 K/P51 ZKL is a super-precision double-row cylindrical roller bearing that offers a unique balance between load-carrying capacity, rigidity, and speed. Its design includes three flanges on the inner ring and no flanges on the outer ring, enabling accommodation of axial displacement in both directions. The separable design simplifies mounting and dismounting, particularly when load conditions require both rings to have an interference fit. The tapered bore allows for accurate adjustment of clearance or preload during mounting.
