NNU4996-SKM-SP – High-precision cylindrical roller bearing for stable brass cage
Quality that safeguards processes
Designed for machine tool spindles, this bearing combines high radial load capacity with smooth concentricity, ensuring stable shaft guidance. This allows for high speed capability, resulting in smooth running even in precision applications.
Design and manufacturing quality
Finely ground raceways guide the rollers precisely, resulting in a smooth power flow, while the precise flange guide stabilizes the set under load. A rigid brass cage further supports the rollers, minimizing settling and maintaining rigidity. Manufacturing details such as SP tolerance class and the precisely guided cylindrical roller geometry complete the design, along with a 1:12 tapered bore that simplifies fit adjustment. The separable rings facilitate assembly and precise alignment within the housing, thus speeding up the setup process.
Convincing in everyday life
Under variable cutting data, the bearing behaves predictably, with machines reacting predictably during acceleration and braking. A lubrication and fit concept tailored to speed and heat management ensures consistency.
Summary
In short: highly rigid, low-friction and easy to assemble – for precise processes and reliable results in continuous use.
