NN 3056 K/SPW33

The NN 3056 K/SPW33 is a super-precision double-row cylindrical roller bearing designed for applications demanding the highest levels of rotational accuracy and stiffness. As a member of the NN 30 series, it features a low cross-sectional height, making it ideal for compact designs where space is limited but high load capacity is essential. The "K" in its designation signifies a tapered bore (1:12 taper), which allows for precise adjustment of internal clearance during mounting. This feature enables users to achieve the optimal preload for maximum system rigidity and running accuracy, a critical requirement for high-performance machinery.

This bearing is built to the "SP" (Super Precision) tolerance class, ensuring extremely tight dimensional and geometrical accuracies. The internal design is optimized to minimize friction and heat generation even at very high rotational speeds. A key advantage of the NN 3056 K/SPW33 is its ability to accommodate heavy radial loads while maintaining exceptional stability. The "W33" suffix indicates the presence of a lubrication groove and three holes in the outer ring, facilitating efficient and reliable lubrication directly to the rolling elements, which is vital for extending service life and maintaining performance in continuous, high-speed operations.

The unique characteristics of the NN 3056 K/SPW33 make it the preferred choice for the main spindles of precision machine tools, such as lathes, milling machines, and grinding centers. Its exceptional rigidity prevents spindle deflection under cutting loads, directly translating to superior workpiece surface finish and dimensional accuracy. The combination of high load capacity, high-speed capability, and adjustable preload ensures that machine tools equipped with this bearing can perform heavier cuts and faster operations without sacrificing precision. This ultimately leads to increased productivity and higher quality output in demanding manufacturing environments.
