NSK Angular Contact Bearings with Sealing 7812, 7813, 7814, 7815

NSK Angular Contact Bearings with Sealing 7812, 7813, 7814, 7815

NSK angular contact bearings 7812, 7813, 7814, and 7815 with sealing are designed for high-speed applications, offering exceptional precision, durability, and protection against contaminants. The sealed design ensures optimal lubrication retention and prevents entry of dust, dirt, and moisture, enhancing the bearing's operational life. These bearings are optimized for handling both axial and radial loads, making them suitable for various industrial machinery applications.

Features and Specifications:

• Sealed Design: Equipped with seals to maintain internal lubrication and block contaminants, reducing the need for maintenance and increasing the bearing's lifespan.
• 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 crafted from steel, brass, or engineering plastic. The retainers are formed by pressing or turning, depending on the bearing type and application requirements.
• Load Capacity: Designed to support significant one-way axial loads. The larger the contact angle, the greater the ability to bear heavy loads.
• Bearing Types: Available in multiple 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 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: Suitable 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, reliable sealing to prevent contamination, and precision 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 life.
