NSK Angular Contact Bearings with Sealing 7200 to 7204

NSK Angular Contact Bearings with Sealing 7200 to 7204

NSK angular contact bearings 7200 to 7204 with sealing are designed for high-speed machine tool applications, providing enhanced precision, durability, and protection against contaminants. The sealed design ensures that dust, dirt, and moisture are kept out while maintaining lubrication within the bearing, extending its operational life. These bearings are ideal for managing both axial and radial loads efficiently in various industrial machinery.

Features and Specifications:

• Sealed Design: Features seals to retain lubrication and prevent contamination, reducing maintenance requirements and enhancing bearing longevity.
• Contact Angle Options: Available in contact angles of 15° (C), 30° (A), 40° (B), and a special 25° (A5). Bearings with larger contact angles have 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. Retainers are formed using pressing or turning techniques, depending on the bearing type and operating conditions.
• Load Capacity: Designed to support significant one-way axial loads. The larger the contact angle, the better the bearing’s ability to handle heavy loads.
• Bearing Types: Available in various configurations:
  • 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 inner and outer diameter variations (ISO4 grade, SU combination)

Applications:

• Industrial Machinery: Widely used in:
  • Metallurgical machinery
  • Mining equipment
  • Paper-making machinery
  • Textile machinery
• Machine Tool Applications: Ideal for supporting ball screws in machine tools, providing high-speed operation with reliable sealing to extend bearing life and enhance performance.

Key Specifications:

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