✨What are the Benefits of choosing NJ1080 bearings?

  • High radial load capacity: The rollers and raceways have line contact, resulting in a rated radial load significantly higher than that of ball bearings of the same size.
  • Good high-speed performance: Generally employs machined or stamped cages, resulting in low friction and suitability for high-speed operation.
  • High rigidity: Minimal elastic deformation effectively supports the shaft and housing, improving the rigidity of the transmission system.
  • Separable design: The inner ring (with roller cage) is separable from the outer ring, facilitating installation, disassembly, and maintenance.
  • Axial displacement adaptability: Types without inner ring flanges (such as NU and N types) allow for free axial expansion and contraction of the shaft relative to the housing, addressing thermal expansion issues.
  • Compact structure: Small cross-sectional height saves radial space.
  • The NJ1080 Single row cylindrical roller bearings adopts a High radial load capacity and high speed performance design, Reference NTN technology, with dimensions an inner diameter of 400 mm, an outer diameter of 600 mm, a width of 90 mm, featuring One (row) construction from NJ10 series (NJ10..) (series), optimal operating temperature is generally -40 to 120 degrees Celsius. With grade precision of P0 (ISO Class NORMAL / ABEC-1) and a clearance of CN, ensure the equipment operates more stably , and the maximum speed can reach (Limit Speed Ratings (grease) rpm:990 Limit Speed Ratings (oil) rpm:1200)for applications involving high radial loads, high speeds, and the pursuit of high rotational accuracy, rigid radial support is provided for the shaft.

🏭 What are the applications of the NJ1080 bearing?

  • Electric Motors and Generators: Support high speeds and reduce frictional temperature rise.
  • Gearboxes: Withstand high radial loads and improve transmission rigidity.
  • Pumps and Compressors: Ensure stable rotor operation and extend service life.
  • Metallurgical Equipment: Resistant to heavy loads and impacts, adaptable to high-temperature conditions.
  • Mining Machinery: Resistant to vibration and dust, maintaining continuous operation.
  • Wind Power Equipment: Reliably transmits torque and adapts to variable speed and load conditions.
  • Rail Transportation: Withstands heavy vehicle loads and ensures safe operation.
  • Machine Tools: Provides high-rigidity support to ensure machining accuracy.
  • Paper Machinery: Maintains roller stability and improves paper quality.
  • Conveying Equipment: Bears continuous loads and reduces downtime for maintenance.
