Angular contact roller bearings are available in a variety of designs, including single row, double row, and four-point contact bearings

angular contact roller bearing. Single row bearings are the most common type and are best suited for applications with light to moderate loads. Double row bearings have a higher load-carrying capacity and are suitable for applications with heavier loads. Four-point contact bearings are designed to handle both radial and axial loads in any direction and are commonly used in applications where high precision and rigidity are required.

However, there are trade-offs when selecting a bearing with a specific contact angle. For example, bearings with a smaller contact angle may have a higher rotational accuracy due to the tighter spacing of the rolling elements. This is particularly important in applications where precise positioning or minimal vibration is required This is particularly important in applications where precise positioning or minimal vibration is required This is particularly important in applications where precise positioning or minimal vibration is required This is particularly important in applications where precise positioning or minimal vibration is requiredcontact angle of bearing. On the other hand, bearings with a larger contact angle may have a higher moment capacity, making them suitable for heavy-duty applications.
