Bearing 13947 – Precision Engineering for Demanding Applications

Self-aligning ball bearing
Self-aligning ball bearings have two rows of balls, a common sphered raceway in the outer ring and two deep uninterrupted raceway grooves in the inner ring. They are insensitive to angular misalignment of the shaft relative to the housing, which can be caused, for example, by shaft deflection.

    Accommodate static and dynamic misalignment
    Excellent high-speed performance
    Excellent light load performance
    Low friction

Knowledge and introduction of bearings

The Self-aligning Ball Bearing 13947 is designed to provide optimal performance in applications that demand high precision, load-bearing capability, and resistance to shaft misalignment. Its unique self-aligning design ensures that it accommodates misalignment up to 3°, making it ideal for systems where shaft deflection or alignment issues are common.

Key Specifications:

1. Dimensions:

• Inner Diameter (d): 35 mm

• Outer Diameter (D): 72 mm

• Width (B): 17 mm
  These dimensions are carefully designed to offer a balance of compact size and high load capacity, ensuring the bearing performs efficiently in both small and medium-sized machinery.

2. Load Capacity:

• Dynamic Load Rating (C): 28.5 kN

• Static Load Rating (C₀): 14.2 kN
  The high dynamic and static load ratings ensure that the bearing can withstand heavy radial and axial loads, making it suitable for a wide range of demanding applications such as industrial machinery, agricultural equipment, and automotive systems.

3. Operating Speed:

• Limiting Speed: 7,200 RPM
  The bearing is designed to perform effectively at high rotational speeds without compromising its operational stability. This feature is critical for high-speed machinery and equipment.

4. Self-aligning Capability: The Self-aligning Ball Bearing 13947 features a spherical outer ring, allowing for automatic alignment in the event of shaft misalignment or distortion. This self-aligning characteristic helps reduce the risk of premature wear, increases operational efficiency, and lowers maintenance costs.

5. Material:

• Constructed from high-grade chromium steel, this bearing offers exceptional durability and resistance to wear, corrosion, and high temperatures. The robust material ensures long-term performance, even in harsh industrial environments.

6. Temperature Range:

• The Self-aligning Ball Bearing 13947 operates effectively within a temperature range of -30°C to +120°C, making it suitable for use in a variety of environments, from high-temperature industrial settings to colder conditions in agricultural machinery.

7. Lubrication:

• Pre-lubricated with high-quality grease or available with customized lubrication options, the bearing ensures minimal friction and efficient performance over an extended service life.

Applications:

Ideal for use in industrial machinery, conveyors, electric motors, pumps, and agricultural equipment, the Self-aligning Ball Bearing 13947 is a versatile solution for equipment that requires reliability, self-alignment, and high load tolerance.
