The NN3011KTN/SPVR521 SKF Precision Cylindrical Roller Bearing from SKF is perfectly engineered to enhance the performance of your machinery. This is a double row bearing with a roller-centred PA66 cage and a 1:12 tapered bore, providing excellent durability, precision, and overall performance. The NN-type has no flanges on the outer ring and three flanges on the inner ring, meaning the outer ring is separable from the inner ring and roller and cage assembly. The NN3011KTN/SPVR521 SKF bearing is constructed with a unique balance between load-carrying capacity, rigidity, and speed to meet the demands of diverse industrial applications, especially machine tools and spindles. The dimensions of the SKF NN3011KTN/SPVR521 bearing are 55x90x26mm.

Key Features

Cylindrical Roller Design

The NN3011KTN/SPVR521 SKF bearing features a cylindrical roller design, optimising load distribution and facilitating high radial load capacity. NN-type has no flanges on the outer ring and three flanges on the inner ring, meaning the outer ring is separable from the inner ring and roller and cage assembly.

Tapered Bore

This NN3011KTN/SPVR521 SKF bearing features a 1:12 tapered bore – suffix K. A tapered bore is preferred on cylindrical roller bearings being used in machine tool applications as the taper enables more accurate adjustment of clearance and preload during fitting.

High-Speed Capability

The NN3011KTN/SPVR521 SKF bearing is designed to handle high-speed operations while maintaining low noise and vibration levels. This ensures smooth and efficient rotation in dynamic environments without compromising stability. This makes it ideal for applications that demand rapid rotation.

Robust Construction

Crafted with high-quality materials and precision engineering, the SKF NN3011 KTN/SPVR521 bearing is built to withstand the rigours of industrial environments. Its robust construction ensures reliable performance, making it an ideal choice for heavy-duty machinery.
