NSK Angular Contact Bearings with Sealing 71815 to 71819

NSK Angular Contact Bearings with Sealing 71815 to 71819

NSK angular contact bearings 71815 to 71819 with sealing are designed for high-speed applications, providing precision, durability, and enhanced protection. The sealed design ensures that contaminants such as dust and moisture are kept out while retaining lubrication, thereby extending the bearing’s operational life. These bearings are ideal for managing both axial and radial loads in various industrial machinery.

Features and Specifications:

• Sealed Design: Incorporates seals to prevent contamination and retain lubrication, which minimizes maintenance and extends bearing life.
• Contact Angle Options: Available in contact angles of 15° (C), 30° (A), 40° (B), and a special 25° (A5). A larger contact angle offers a greater capacity to handle higher axial loads.
• Material and Construction: Made from high-quality steel balls with retainers constructed of steel, brass, or engineering plastic. The retainers are formed through pressing or turning, depending on the bearing type and application conditions.
• Load Capacity: Designed to manage significant one-way axial loads. Bearings with larger contact angles have an increased capacity for supporting heavy loads.
• Bearing Types: Available in various configurations to suit different applications:
  • Single Row Angular Contact Ball Bearing
  • Matched Angular Contact Ball Bearing
  • Double Row Angular Contact Ball Bearing
  • Four-Point Contact Ball Bearing
• Combination Options:
  • DF: Face-to-face combination
  • DB: Back-to-back combination
  • DT: Tandem combination
  • SU: Single, free combination
  • DU: Dual column, free combination
  • 3-Column Combinations: DBD, DFD, DTD
  • 4-Column Combinations: DBB, DFF, DBT, DFT, DTT
• Precision and Preload:
  • C10: Standard preloaded for improved stability
  • C9: Light preloaded, suitable for low torque applications
  • PN7A: Standard precision (ISO4 class equivalent)
  • PN7B: Special control precision for specific inner and outer diameter variations (ISO4 grade, SU combination)

Applications:

• Industrial Machinery: Ideal for use in:
  • Metallurgical machinery
  • Mining equipment
  • Paper-making machinery
  • Textile machinery
• Machine Tool Applications: Specifically designed for ball screw support in machine tools, ensuring high-speed operation with reliable sealing for extended life and optimal performance.

Key Specifications:

• Inner Diameter: Starting from 25 mm (0.98 inches)
• Contact Angle: Options include 15°, 30°, 40°, and a special 25° for versatile load-handling capabilities.
• Sealing: Dust-proof and moisture-resistant seals ensure optimal protection and extended lifespan.
