NSK Angular Contact Bearings with Sealing 71800 to 71804

NSK Angular Contact Bearings with Sealing 71800 to 71804

NSK angular contact bearings 71800 to 71804 with sealing are crafted for high-speed applications, delivering high precision and durability. The sealed design protects against contaminants and retains lubrication, significantly enhancing the bearing's lifespan and performance in demanding machine tool environments. These bearings can handle both axial and radial loads efficiently.

Features and Specifications:

• Sealed Design: Equipped with seals to retain lubrication and prevent contaminants such as dust, dirt, and moisture from entering the bearing. This design extends the bearing's operational life.
• Contact Angle Options: Available in contact angles of 15° (C), 30° (A), 40° (B), and a special 25° (A5). Bearings with larger contact angles provide greater capacity to handle axial loads.
• Material and Construction: Made with high-quality steel balls. Retainers are constructed from steel, brass, or engineering plastic, formed using pressing or turning methods based on the bearing type and operational conditions.
• Load Capacity: Designed to manage substantial one-way axial loads, with larger contact angles supporting heavier loads.
• Bearing Types: Available in various configurations for multiple application needs:
  • 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 stable operation
  • C9: Light preloaded for low-torque requirements
  • PN7A: Standard precision (ISO4 class equivalent)
  • PN7B: Special control precision for inner and outer diameter variations (ISO4 grade, SU combination)

Applications:

• Industrial Machinery: Suitable for use in:
  • Metallurgical machinery
  • Mining equipment
  • Paper-making machinery
  • Textile machinery
• Machine Tool Applications: Designed specifically for ball screw support in machine tools, delivering high-speed performance while ensuring the prevention of contamination for prolonged bearing life.

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 ensure optimal protection and extended lifespan.
