Overview Of Ball Bearings

A ball bearing is a type of rolling-element bearing that serves three main functions while it facilitates motion: it carries loads, reduces friction and positions moving machine parts. They can bear both radial and axial loads, so they can be developed for many different applications, load types, and speeds.

Ball bearings are usually made of different materials such as stainless steel, ceramic, or chrome steel, but the materials and overall design can vary greatly depending on the specific job at hand. The bearing materials can also include flanges, cages, and multi-row bearings to achieve higher performance to meet specific application requirements.

Features of Ball Bearings

The inner ring of this type of bearing has two raceways and the outer ring has a single spherical raceway with its center of curvature coincident with the bearing axis. Therefore, the axis of the inner ring, balls, and cage can deflect to some extent around the bearing center.

Applications of Ball Bearings:

Different types of ball bearings may have different applications, let’s check them out:

Angular Contact Bearings: designed to work under combined radial and axial loads.

Axial Bearings: also called thrust ball bearings, these are designed to work under the force applied parallel to the bearing's axis, or thrust loads.

Deep-Groove Bearings: designed to carry both radial and light axial loads.

Linear Bearings: designed to allow movement in one direction along a linear axis.

Self-aligning Ball Bearings: bearings with two sets of balls that are self-aligning and to carry both radial and light axial loads.

High-Speed Angular Contact Bearings: another type of precision ball bearing is a high-speed angular contact bearing. As the name implies, high-speed bearings are designed to handle high RPMs with precision and accuracy.

Ball Bearings Types

  • Suspension conveyor chain bearing
    Some models of our company are designed with dust cover, which can store high temperature grease and make high temperature chain more durable.Production of a variety of types of suspension conveyor chain bearings, a variety of types of walking wheel, a variety of structure of the guide wheel, to adapt to a variety of loads, a variety of pitch of the suspension conveyor equipment, to meet the different design of more options.
  • Pillow block ball bearings  UC205  UCP205
    The outer spherical ball bearing is actually a variant of the deep groove ball bearing, which is characterized by the spherical outer diameter surface of its outer ring, which can be fitted into the corresponding concave spherical surface of the bearing seat to play the role of self-aligning. Outer spherical bearing is mainly used to bear radial and axial combined load which is mainly radial load. Generally, it is not suitable to bear axial load alone.Spherical bearings are preferred for applications requiring simple equipment and parts, such as agricultural machinery, transportation system or construction machinery.
  • Deep Groove Ball Bearings 6205
    Deep groove ball bearings for high-speed or even high-speed operation, very durable, do not need frequent maintenance. The bearing has the advantages of small friction coefficient, high limit speed, various sizes and forms, they are widely used in precision instruments, low noise motors, gearboxes, meters, engines, household appliances, internal combustion engines, vehicles, agricultural machinery, construction machinery, construction machinery, skates, clay balls, automobiles, motorcycles and general machinery industries.
  • Pillow block ball bearings  UC204  UCP204
    Spherical bearings are preferred for applications requiring simple equipment and parts, such as agricultural machinery, transportation system or construction machinery.
  • Thrust ball bearings  51120   8120
    The thrust ball bearing is designed to bear thrust load at high speed, which is composed of washer ring with ball rolling raceway groove. Because the ring is cushion shaped, the thrust ball bearing can be divided into two types: flat bottom cushion type and self-aligning spherical cushion type. In addition, the bearing can bear axial load, but not radial load.
  • Angular contact ball bearing   7310AC   46310
    Angular contact ball bearing can bear radial load and axial load at the same time. It can work at high speed. The larger the contact angle is, the higher the axial bearing capacity is. The contact angle is the angle between the line of contact point between ball and raceway in radial plane and the vertical line of bearing axis. The contact angle of high precision and high speed bearings is usually 15 degrees. Under the action of axial force, the contact angle will increase.
  • Self-aligning Ball Bearings   1204
    The self-aligning ball bearing has cylindrical hole and conical hole. The cage is made of steel plate and synthetic resin. Its feature is that the outer ring raceway is spherical, with automatic self-aligning, which can compensate the errors caused by different centrality and shaft deflection, but the relative inclination of the inner and outer rings shall not exceed 3 degrees.
  • Deep Groove Ball Bearings 6204
    Deep groove ball bearings for high-speed or even high-speed operation, very durable, do not need frequent maintenance. The bearing has the advantages of small friction coefficient, high limit speed, various sizes and forms, they are widely used in precision instruments, low noise motors, gearboxes, meters, engines, household appliances, internal combustion engines, vehicles, agricultural machinery, construction machinery, construction machinery, skates, clay balls, automobiles, motorcycles and general machinery industries.
