N 1018 KTN9/SP

The N 1018 KTN9/SP is a super-precision single-row cylindrical roller bearing designed for applications where exceptional accuracy, high speed capability, and rigid support are paramount. Its key feature is the tapered bore, which allows for precise adjustment of internal clearance and preload, crucial for maintaining shaft stability and minimizing vibration in high-speed rotating machinery like machine tool spindles. Manufactured to stringent Class SP tolerances, this bearing ensures minimal runout and superior dimensional stability, translating directly into improved machining quality and extended tool life. The non-metallic cage design further contributes to low friction and quiet operation, even at extreme rotational velocities.

This bearing's design offers significant advantages for performance-critical applications. The separable construction simplifies mounting and allows for independent adjustment of the inner and outer rings, facilitating optimal bearing setup. The N-design, with its lack of flanges on the outer ring, permits axial displacement of the shaft relative to the housing in both directions, making it ideal for non-locating bearing arrangements that accommodate thermal expansion. With a capacity for high speeds (up to 7,000 r/min with grease lubrication and 8,000 r/min with oil-air lubrication), low friction, and excellent radial load support, the N 1018 KTN9/SP is the benchmark for precision and reliability in demanding industrial environments.
