Angular Contact Ball Bearings are high-performance precision components engineered to sustain combined radial and axial loads simultaneously. Featuring a specialized contact angle between the inner and outer rings—typically ranging from 15° to 40°—these bearings are optimized for high-speed rotation and rigorous industrial applications. The larger the contact angle, the higher the axial load capacity, providing versatile solutions for complex mechanical requirements.

Our product range includes single-row, double-row centripetal thrust structures, and four-point contact ball bearings. To enhance spindle stiffness and manage axial displacement, these bearings are often deployed in duplex arrangements with adjustable internal clearance. Utilizing high-grade materials and advanced cage designs—including steel plate stamped, polyamide formed, and copper alloy cutting cages—we ensure maximum stability and longevity in demanding environments.

Frequently Asked Questions

Q: How does the contact angle affect the bearing's performance?

A larger contact angle increases the bearing's capacity to handle axial loads, while a smaller contact angle is more suitable for high-speed rotation due to reduced friction.

Q: What is the purpose of a duplex arrangement?

Duplex arrangements are used to carry axial loads in both directions and to increase the stiffness of the spindle through preloading or clearance adjustment.

Q: When should I choose a polyamide cage over a steel one?

Polyamide formed cages are generally preferred for high-precision bearings with contact angles below 30° to optimize performance and reduce noise.

Q: What makes a four-point contact ball bearing unique?

Four-point contact bearings act as a single-row radial thrust bearing that can withstand axial loads in both directions, saving space while maintaining functionality.

Q: Can these bearings be used with both oil and grease lubrication?

Yes, our angular contact ball bearings are designed to be compatible with both grease and oil, depending on the speed and temperature requirements of your application.

Q: Which industry typically utilizes these bearings the most?

They are widely used in the general equipment manufacturing industry, specifically in machine tool spindles, automotive components, and precision robotics.
