NSK Angular contact ball high speed machine tool bearings 7208

JAPAN NSK 7208 Angular Contact Ball Bearing – High-Speed Machine Tool Bearings

Product Overview:

The NSK 7208 Angular Contact Ball Bearing is engineered for high-speed machine tool applications. Designed to handle significant axial loads in one direction, these bearings are essential for machines that require stability and precision. With contact angles available in 15°, 30°, and 40°, the bearing is built to support various load capacities, making it suitable for use in machinery such as metallurgy, mining, and paper production.

Key Features:

• Material: Constructed with high-quality steel, brass, or engineering plastic.
• Contact Angles: Available in 15°, 30°, 40° for different load-bearing capacities.
• Precision: Supports high-speed operations with low friction, ensuring stable performance.
• Bearing Variations:
  • Single row angular contact ball bearing
  • Matched angular contact ball bearing
  • Double row angular contact ball bearing
  • Four-point contact ball bearing
