Product Description
Angular Contact Ball Bearing
Product Description
angular contact ball bearing can bear radial load and axial load at the same time. It can work at higher speeds. The larger the contact angle, the higher the axial load carrying capacity. High-precision and high-speed bearings usually take a contact angle of 15 degrees. Under the action of axial force, the contact angle will increase. model | Inner diameter (mm) | Outer diameter (mm) | Width (mm) | Weight (g) | Dynamic /Staticload (n) |

Preload
There are several methods used to preload 72 series angular contact ball bearings, including light, medium, and heavy preload. Light preload provides minimal clearance and is suitable for high-speed applications. Medium preload offers a balance between high rigidity and low noise levels, and is commonly used for machine tool applications. Heavy preload provides maximum rigidity and is ideal for high load and high precision applications. Proper preload can ensure accurate positioning and reduce the risk of bearing damage due to vibration or shock. The specific preload method used depends on the application requirements and load conditions.
There are several ways to pair 72 series angular contact ball bearings, including back-to-back, face-to-face, tandem, and multiple combinations. Back-to-back pairing provides high rigidity and load capacity, while face-to-face pairings provide high precision and reduced axial load capacity. Tandem pairing allows for higher speed and reduced noise, while multiple combinations offer greater flexibility and versatility in design. Proper pairing can enhance bearing performance and increase machine reliability, leading to improved efficiency and reduced maintenance costs. It is important to choose the correct pairing method based on the specific application requirements and load conditions.
Application Scenario
The 72 series angular contact ball bearings are widely used in high-speed and high-precision applications such as machine tool spindles, motors, and generators. They can support both radial and axial loads, and the contact angle can be adjusted to provide different levels of axial load capacity. These bearings provide increased rigidity and accuracy in critical applications, and are designed to withstand high-speed rotation without excessive noise or vibration. They are commonly used in industries such as aerospace, automotive, and medical equipment manufacturing to ensure smooth and reliable operation of machinery and equipment.
