Product Description
Â
Self-aligning ball bearings are bearings with steel balls and cage assemblies between the 2 raceways inner ring and spherical raceways outer ring.
Self-aligning ball bearing has 2 structures of cylindrical hole and conical hole. The material of the cage is steel plate, synthetic resin, engineering plastic and so on.
The self-aligning ball bearing can have sealing structure similar to the deep groove ball bearing, but it will affect the self-alignment of the bearings.
Self-aligning ball bearings mainly bear radial load, and can bear small axial load at the same time. It can’t bear pure axial load. Due to the structure, the limit speed of self-aligning ball bearings is relatively low.
The characteristic of self-aligning ball bearing is that the outer ring raceway is spherical.Since the curvature center of the outer ring raceway surface is consistent with the bearing center, it has the self-aligning function, allowing the axis of the inner ring, balls and cage to deflect around the bearing center, which can compensate for the errors caused by the misalignment and the deflection of the shaft and the outer casing, but the relative inclination of the inner and outer rings should not exceed 3 degrees. This type of bearing is mostly used on double support shafts that are prone to bending under load, and in components where the housing seat hole cannot be strictly coaxial.

Main applications:
Metallurgy, rolling mill, mining, petroleum, paper, cement, textile, sugar extraction and other industries and general machinery.

How do Miniature Ball Bearings Differ from Standard-sized Ones, and Where are They Commonly Used?
Miniature ball bearings, as the name suggests, are smaller in size compared to standard-sized ball bearings. They have distinct characteristics and are designed to meet the unique requirements of applications that demand compactness, precision, and efficient rotation in confined spaces. Here’s how miniature ball bearings differ from standard-sized ones and where they are commonly used:
- Size:
The most noticeable difference is their size. Miniature ball bearings typically have outer diameters ranging from a few millimeters to around 30 millimeters, while standard-sized ball bearings have larger dimensions suitable for heavier loads and higher speeds.
- Load Capacity:
Due to their smaller size, miniature ball bearings have lower load-carrying capacities compared to standard-sized bearings. They are designed for light to moderate loads and are often used in applications where precision and compactness are prioritized over heavy load support.
- Precision:
Miniature ball bearings are known for their high precision and accuracy. They are manufactured to tighter tolerances, making them suitable for applications requiring precise motion control and low levels of vibration.
- Speed:
Miniature ball bearings can achieve higher speeds than standard-sized bearings due to their smaller size and lower mass. This makes them ideal for applications involving high-speed rotation.
- Friction and Efficiency:
Miniature ball bearings generally have lower friction due to their smaller contact area. This contributes to higher efficiency and reduced heat generation in applications that require smooth and efficient motion.
- Applications:
Miniature ball bearings find applications in various industries and sectors:
- Electronics and Consumer Devices:
They are used in small motors, computer disk drives, printers, and miniature fans, where space is limited but precise motion is essential.

They are used in applications like UAVs (drones), aerospace actuators, and satellite components where size and weight constraints are critical.
- Optics and Instrumentation:
Miniature bearings play a role in optical instruments, cameras, and measuring devices, providing smooth rotation and accurate positioning.
Overall, miniature ball bearings are specialized components designed for applications where space, precision, and efficient rotation are paramount. Their compactness and high precision make them crucial in various industries requiring reliable motion control in limited spaces.
What are the Different Components that Make up a Typical Ball Bearing?
A typical ball bearing consists of several essential components that work together to reduce friction and support loads. Here are the main components that make up a ball bearing:
- Outer Ring:
The outer ring is the stationary part of the bearing that provides support and houses the other components. It contains raceways (grooves) that guide the balls’ movement.
- Inner Ring:
The inner ring is the rotating part of the bearing that attaches to the shaft. It also contains raceways that correspond to those on the outer ring, allowing the balls to roll smoothly.
- Balls:
The spherical balls are the rolling elements that reduce friction between the inner and outer rings. Their smooth rolling motion enables efficient movement and load distribution.
- Cage or Retainer:
The cage, also known as the retainer, maintains a consistent spacing between the balls. It prevents the balls from touching each other, reducing friction and preventing jamming.
- Seals and Shields:
Many ball bearings include seals or shields to protect the internal components from contaminants and retain lubrication. Seals provide better protection against contaminants, while shields offer less resistance to rotation.
- Lubricant:
Lubrication is essential to reduce friction, wear, and heat generation. Bearings are typically filled with lubricants that ensure smooth movement between the balls and raceways.
- Flanges and Snap Rings:
In some designs, flanges or snap rings are added to help position and secure the bearing in its housing or on the shaft. Flanges prevent axial movement, while snap rings secure the bearing radially.
- Raceways:
Raceways are the grooved tracks on the inner and outer rings where the balls roll. The shape and design of the raceways influence the bearing’s load-carrying capacity and performance.
- Anti-Friction Shield:
In certain high-speed applications, a thin anti-friction shield can be placed between the inner and outer rings to minimize friction and heat generation.
These components work together to enable the smooth rolling motion, load support, and reduced friction that characterize ball bearings. The proper design and assembly of these components ensure the bearing’s optimal performance and longevity in various applications.
