Product Description

Key Features of Single Row Angular Contact Ball Bearing

(Custom configurations available upon request.)

Contact Angle:

Designed with a specific contact angle (typically 15°, 25°, or 40°) to handle combined loads (radial and axial). The contact angle defines the direction of axial load that the bearing can sustain.
Load Handling:

Optimized for handling high axial loads in one direction in addition to radial loads.
Not suitable for pure radial loads or axial loads in the opposite direction unless paired with another bearing.
Speed Capability:

High-speed performance due to precise alignment of rolling elements and reduced friction.
Material:

Typically made of high-quality bearing steel or stainless steel for durability and wear resistance.
Options for ceramic rolling elements (hybrid bearings) are available for applications requiring reduced weight, higher speed, or low thermal expansion.
Preload Options:

Often preloaded during installation or in manufacturing to reduce internal clearance, enhance stiffness, and improve positional accuracy.
Configurations:

Can be used in single, paired (back-to-back, face-to-face, or tandem), or multi-bearing arrangements to meet specific load and rigidity requirements.
Cage Material:

Comes with a variety of cage designs, such as polyamide, brass, or steel, to optimize performance based on operating conditions.
Applications:

Widely used in high-precision and high-speed applications such as machine tools, pumps, compressors, electric motors, gearboxes, and automotive components.
Lubrication Options:

Available with grease lubrication, oil lubrication, or as sealed units for maintenance-free operation.

FAQ

1. What are ceramic bearings?
Ceramic bearings are bearings made from advanced ceramic materials such as Zirconia (ZrO2) or Silicon Nitride (Si3N4). They are known for their high strength, wear resistance, and ability to perform in extreme conditions.

2. What are the advantages of ceramic bearings over steel bearings?
Ceramic bearings offer several advantages, including:

  Higher Durability: Resistant to wear, corrosion, and high temperatures.
  Lighter Weight: Up to 40% lighter than steel bearings.
  Non-Magnetic & Electrically Insulating: Ideal for sensitive applications.
  Low Friction: Reduces energy loss and heat generation.
3. In which industries are ceramic bearings commonly used?
Ceramic bearings are widely used in:

  Packaging equipment
  Renewable energy (e.g., wind turbines)
  Aerospace and automotive
  Medical devices
  Chemical processing
  High-precision tools
4. Can ceramic bearings handle high temperatures?
Yes, ceramic bearings are highly resistant to heat and can operate in temperatures exceeding 1,000°C, depending on the material used.

5. Are ceramic bearings suitable for corrosive environments?
Absolutely! Ceramic bearings are non-reactive to most chemicals, making them ideal for use in highly corrosive environments.

6. What is the lifespan of ceramic bearings?
Ceramic bearings typically last much longer than steel bearings due to their wear resistance and durability. However, the exact lifespan depends on the operating conditions and maintenance practices.

7. How do I maintain ceramic bearings?
Ceramic bearings require minimal maintenance, but to ensure longevity:

  Use the correct lubrication when necessary.
  Keep them clean and free from contaminants.
  Follow proper installation procedures.
