NSK Angular Contact Bearings with Sealing 7816 to 7819

NSK Angular Contact Bearings with Sealing 7816 to 7819

NSK angular contact bearings 7816 to 7819 with sealing are engineered for high-speed applications, ensuring superior precision, durability, and optimal protection against contaminants. The sealed design effectively retains lubrication while preventing the entry of dust, dirt, and moisture, thereby extending the bearing's operational life. These bearings are capable of managing both axial and radial loads, making them suitable for various industrial machinery.

Features and Specifications:

• Sealed Design: Features seals that maintain lubrication and block contaminants, reducing maintenance and enhancing the bearing's lifespan.
• Contact Angle Options: Available in contact angles of 15° (C), 30° (A), 40° (B), and a special 25° (A5). Larger contact angles provide a greater capacity for handling high axial loads.
• Material and Construction: Constructed with high-quality steel balls and retainers made from steel, brass, or engineering plastic. The retainers are formed through pressing or turning, depending on the bearing's design and application requirements.
• Load Capacity: Designed to manage substantial one-way axial loads. The larger the contact angle, the higher the load-bearing capacity.
• Bearing Types: Available in different configurations for various 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 operational 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, offering high-speed operation with reliable sealing for extended bearing life and precise motion control.

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 bearing lifespan.
