Bearing NN3019-KM-P42 FAG

Product detailed description

The FAG NN 3019 KM.P42 is a super-precision double-row cylindrical roller bearing engineered to provide exceptional load-carrying capacity, high rigidity, and precise running accuracy. This bearing is ideal for applications requiring high-speed operation and minimal noise and vibration.

Key Features:

• Design: Double-row cylindrical roller bearing with three flanges on the inner ring and no flanges on the outer ring, allowing for axial displacement in both directions.

• Bore Type: Tapered bore with a taper ratio of 1:12, facilitating accurate adjustment of clearance or preload during mounting.

• Cage Material: Non-metallic cage design to reduce friction and wear.

• Lubrication: Open design without sealing, suitable for applications where external sealing is provided.

Technical Specifications:

• Dimensions:

  • Bore Diameter: 95 mm
  • Outside Diameter: 145 mm
  • Width: 37 mm

• Load Ratings:

  • Basic Dynamic Load Rating: 142 kN
  • Basic Static Load Rating: 232 kN

• Speed Ratings:

  • Attainable Speed for Grease Lubrication: 6,000 rpm
  • Attainable Speed for Oil-Air Lubrication: 6,700 rpm

• Material: High-quality bearing steel for durability and performance.

• Clearance: Radial internal clearance class C1, suitable for high-precision applications.

• Tolerance Class: Class SP (Super Precision) for stringent dimensional and running accuracy.

This bearing is commonly used in machine tools, printing machinery, and other high-precision equipment where high radial load capacity and rigidity are essential. Its separable design simplifies mounting and dismounting, particularly when load conditions require both rings to have an interference fit.
