Product Description
Product Description
Angular contact ball bearings have inner and outer ring raceways that are displaced relative to each other in the direction of the bearing axis. This means that these bearings are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads.
We offer comprehensive ranges of angular contact ball bearings, which are available in:
– Single row and double row
– Open and sealed types
– Contact angle of 15, 30 or 40 degree
– Chrome steel, ceramic or hybrid materials
– Polyamide, steel and brass cage assemblies
Product Parameters
Double Row Angular Contact ball bearings have 2 rows of balls arranged back-to-back. The lines of action of the load at the contact between balls and raceways (load lines) diverge at the bearing axis and form an angle of 30° to the radial plane.

What are the Challenges Associated with Noise Reduction in Ball Bearings?
Noise reduction in ball bearings is a crucial consideration, especially in applications where noise levels must be minimized for operational efficiency and user comfort. While ball bearings are designed to operate smoothly, there are several challenges associated with reducing noise in their operation:
- Vibration:
Vibration generated by the movement of rolling elements and raceways can lead to noise. Even minor irregularities in bearing components or the mounting system can cause vibration that translates into audible noise.
- Bearing Type and Design:
The type and design of the ball bearing can impact noise generation. For example, deep groove ball bearings are known for their quiet operation, while angular contact bearings can generate more noise due to their higher contact angles.
- Lubrication:
Improper or inadequate lubrication can result in increased friction and wear, leading to noise. Choosing the right lubricant and maintaining proper lubrication levels are essential for reducing noise in ball bearings.
- Bearing Clearance and Preload:
Incorrect clearance or preload settings can lead to noise issues. Excessive clearance or inadequate preload can cause the rolling elements to impact the raceways, resulting in noise during rotation.
- Material and Manufacturing Quality:
The quality of materials and manufacturing processes can affect noise levels. Inconsistent or low-quality materials, improper heat treatment, or manufacturing defects can lead to noise generation during operation.
- Surface Finish:
The surface finish of the rolling elements and raceways can impact noise. Rough surfaces can generate more noise due to increased friction and potential irregularities.
- Sealing and Shielding:
Seals and shields that protect bearings can influence noise levels. While they are necessary for contamination prevention, they can also cause additional friction and generate noise.
- Operating Conditions:
External factors such as temperature, speed, and load can influence noise levels. High speeds or heavy loads can amplify noise due to increased stress on the bearing components.
- Wear and Deterioration:
As ball bearings wear over time, noise levels can increase. Worn components or inadequate lubrication can lead to more significant noise issues as the bearing operates.
To address these challenges and reduce noise in ball bearings, manufacturers and engineers employ various techniques, such as optimizing design, selecting suitable bearing types, using proper lubrication, maintaining accurate preload settings, and ensuring high-quality materials and manufacturing processes. Noise reduction efforts are essential to improve overall product quality, meet noise regulations, and enhance user experience in various applications.
What Role do Seals and Shields Play in Protecting Ball Bearings from Dirt and Debris?
Seals and shields are critical components of ball bearings that play a crucial role in protecting them from dirt, debris, moisture, and contaminants in various applications. These protective features help maintain the integrity of the bearing’s internal components and ensure reliable operation. Here’s how seals and shields contribute to bearing protection:
- Contaminant Exclusion:
Seals and shields create a physical barrier between the external environment and the bearing’s interior. They prevent dust, dirt, water, and other contaminants from entering the bearing and coming into contact with the rolling elements and raceways.
- Lubrication Retention:
Seals and shields help retain lubrication within the bearing. They prevent the lubricant from escaping and contaminants from entering, ensuring that the bearing remains properly lubricated for smooth operation and reduced friction.
- Corrosion Prevention:
Seals and shields protect bearing components from exposure to moisture and corrosive substances. By preventing moisture ingress, they help extend the bearing’s lifespan by minimizing the risk of corrosion-related damage.
- Extended Bearing Life:
Seals and shields contribute to the overall longevity of the bearing by reducing wear and damage caused by contaminants. They help maintain a clean internal environment, which promotes proper rolling contact and minimizes the risk of premature failure.
- Enhanced Performance in Harsh Environments:
In applications exposed to harsh conditions, such as outdoor machinery or industrial settings, seals and shields are vital. They protect bearings from abrasive particles, chemicals, and extreme temperatures, ensuring reliable performance despite challenging conditions.
- Noise and Vibration Reduction:
Seals and shields can help reduce noise and vibration generated by the bearing. They provide additional damping and stability, contributing to smoother operation and enhanced user comfort in noise-sensitive applications.
- Customized Protection:
Manufacturers offer a variety of seal and shield designs to suit different application requirements. Some seals provide higher levels of protection against contamination, while others are designed for high-speed or high-temperature environments.
- Trade-Offs:
While seals and shields offer significant benefits, they can also introduce some friction due to contact with the bearing’s inner or outer ring. Engineers must balance the level of protection with the desired operating characteristics, considering factors like friction, speed, and environmental conditions.
Overall, seals and shields play a vital role in maintaining the integrity and performance of ball bearings. By effectively preventing contaminants from entering and preserving lubrication, they ensure the smooth and reliable operation of machinery and equipment in a wide range of applications.
