• Structure:

  • Angular contact ball bearings consist of an inner ring, outer ring, rolling elements (steel balls), and a cage.

  • The raceways of the inner and outer rings are designed at a specific angle (contact angle), enabling the bearing to withstand both axial and radial loads.

  • The contact angle is typically 15°, 25°, 30°, or 40°. A larger contact angle provides greater axial load capacity.

• Features:

  • High-speed capability: The compact design and low friction make angular contact ball bearings suitable for high-speed operation.

  • High precision: Commonly used in precision machinery, such as machine tool spindles and robotics.

  • Combined load capacity: Can withstand both radial and axial loads simultaneously.

  • Paired use: Can be mounted in pairs (back-to-back, face-to-face, or tandem) to handle bidirectional axial loads or higher radial loads.

Types

Based on design and application requirements, angular contact ball bearings can be categorized into the following types:

• Single-row angular contact ball bearings:

  • Can only withstand unidirectional axial loads.

  • Typically require paired installation to handle bidirectional loads.

• Double-row angular contact ball bearings:

  • Equivalent to a combination of two single-row bearings, capable of withstanding bidirectional axial loads.

  • More compact design, suitable for applications with limited radial space.

• Four-point contact ball bearings:

  • Can withstand bidirectional axial loads.

  • Ideal for applications with high axial loads and requiring high rigidity.

• High-speed angular contact ball bearings:

  • Use ceramic balls or special cage designs, suitable for ultra-high-speed applications.

 

plications

Angular contact ball bearings are widely used in the following fields:

• Machine tools: Used in high-precision, high-speed components such as spindles and lead screws.

• Automotive: Used in wheel hubs, gearboxes, and differentials.

• Aerospace: Used in high-precision, high-reliability components such as engines and landing gear.

• Robotics: Used in joints and rotating components.

• Electric motors: Used in high-speed motors and generators.

Selection and Installation

• Selection Considerations:

  • Choose the contact angle based on load direction: A larger contact angle is suitable for higher axial loads, while a smaller contact angle is better for higher radial loads.

  • Select the bearing type based on speed: High-speed applications require high-speed angular contact ball bearings or ceramic ball bearings.

  • Choose single-row or double-row bearings based on installation space.

• Installation Notes:

  • Angular contact ball bearings are often installed in pairs to ensure bidirectional load capacity.

  • Pay attention to the bearing orientation during installation to ensure the load acts on the correct contact angle.

  • Use dedicated tools for installation to avoid direct hammering on the bearing.

Installation Instructions

Installation Guide for Angular Contact Ball Bearings

1. Preparation Before Installation

Before installing angular contact ball bearings, follow these steps to ensure optimal performance:

• Check the bearing: Inspect for any visible damage, contamination, or corrosion before installation.
• Clean components: Ensure that the bearing housing and shaft are clean, dry, and free of dust or metal particles.
• Lubrication: Use the appropriate grease or oil for lubrication, considering the application requirements.

2. Installation Methods

A. Single Angular Contact Ball Bearings Installation

• These bearings must be installed in a specific direction, as they can only support axial loads in one direction.
• Ensure that the marked side or thicker ring is facing the axial load direction.
• Use a press or induction heater to mount the bearing onto the shaft to avoid damage.

B. Paired or Matched Bearings Installation

Angular contact ball bearings are often used in pairs or sets to handle axial loads in both directions. Common arrangements include:

• Back-to-Back (DB, "O" arrangement) - For high rigidity and resistance to moment loads.
• Face-to-Face (DF, "X" arrangement) - Suitable for applications where shaft alignment may vary.
• Tandem (DT arrangement) - Used to accommodate high axial loads in one direction.
  When installing matched bearings, ensure they are positioned correctly as per the arrangement type.

C. Press-Fit Installation

• Always apply force only to the inner ring when mounting on the shaft and to the outer ring when pressing into the housing.
• Avoid direct hammering; use a fitting tool or press to prevent bearing damage.
• If using an induction heater, do not exceed 120°C (248°F) to avoid material expansion and deformation.

3. Post-Installation Checks

• Rotate the shaft manually to ensure smooth movement and no abnormal noise.
• Verify preload settings if applicable, especially for high-speed applications.
• Check axial play and alignment to prevent premature wear.

4. Bearing Suffix Meanings

Understanding bearing suffix codes helps in selecting the right bearing for your application:

Suffix	Meaning
B	40° contact angle
C	15° contact angle
AC	25° contact angle
DB	Back-to-back arrangement
DF	Face-to-face arrangement
DT	Tandem arrangement
P4, P5	High precision class (P4: higher precision than P5)
TN	Nylon cage
M	Brass cage
2RS	Sealed on both sides
ZZ	Shielded on both sides
H	High-speed design

5. Maintenance Tips

• Regularly inspect for wear, noise, or excessive vibration.
• Keep bearings properly lubricated for extended service life.
• Replace bearings at signs of abnormal temperature rise or rough rotation.
