Product Description

Product Description

Product Description

    Angular contact ball bearings are designed to support both radial and axial loads at high speeds. Unlike deep groove ball bearings, these bearings have a contact angle that enables them to handle higher axial loads in one direction or combined loads efficiently. They are widely used in machinery, automotive, aerospace, and precision equipment applications.

Key Features

High Load Capacity - Designed to withstand both radial and axial forces with optimized ball and raceway contact.
Multiple Contact Angles - Available in 15°, 25°, 30°, and 40° to suit different load requirements.
High-Speed Performance - Manufactured with precision to ensure smooth rotation and minimal friction for high-speed applications.Long Service Life - Made from premium bearing steel with advanced heat treatment for enhanced durability.
Single-Row & Double-Row Options -

• Single-row bearings support axial loads in one direction.
• Double-row bearings handle axial loads in both directions.
• OEM & Customization - We offer custom sizes, special coatings, and lubrication options to meet your application needs.

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.

Advantages and Limitations

• Advantages:

  • High-speed capability.

  • High precision and rigidity.

  • Combined load capacity.

  • Compact design, saving space.

• Limitations:

  • Single-row bearings can only withstand unidirectional axial loads.

  • Installation and adjustment are relatively complex, requiring expertise and specialized

Maintenance and Care

• Regularly inspect the lubrication condition to ensure sufficient and clean lubricant.

• Avoid overloading or impact loads to prevent bearing damage.

• For high-speed or high-temperature applications, choose high-temperature lubricants or special material bearings.

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.
