Types of Self-aligning Ball Bearing
2220 M Self-aligning Ball Bearing
2220 M self-aligning ball bearings have two rows of balls with a common spherical raceway in the outer ring and two deep, continuous raceway grooves in the inner ring.
1202S Self-Aligning Ball Bearing
1202s bearing is a rolling bearing composed of inner ring, outer ring, steel ball and cage. It adopts self-aligning design, which can adapt to a certain range of axial and radial misalignment, and supports the movement of the bearing shaft.

Components of Self-aligning Ball Bearing
Ball Bearing Components
Ball bearings are comprised of four main parts: A large ring (outer ring), a small ring (inner ring), balls between the rings (steel balls), and a cage.
Inner Ring and Outer Ring
The inner and outer rings are typically made from high-purity, chrome alloy steel. This material has the necessary hardness and purity important factors for high load ratings and a long service life.
Balls Of The Bearing
Balls of a bearing separate the inner ring and outer ring and permit the bearing to rotate with minimal friction. The radius of the ball is made slightly smaller than the grooved ball track on the inner and outer rings. This makes the balls to contact the rings at a single point. Ball dimensions are further controlled to very high accuracy. Ball roundness, surface finish, and size variations are important attributes. These attributes are controlled to a micro inch level.
Cage
The cage is responsible for keeping the rolling elements separated while guiding them in motion. The materials used include steel, brass, and plastic.
Features of Self-aligning Ball Bearing
》In general, rolling bearings offer lower friction with high rigidity.
》Dimensions, accuracy, markings, and so on are standardized internationally (ISO, ANSI/ABMA, JIS, etc.), making rolling bearings readily available and interchangeable.
》Rolling bearings are easy to maintain, replace, and inspect.
》Depending on the type, rolling bearings can take radial, axial (thrust), moment, or combined loads.
》Rolling bearings can be used over a wide temperature range.
Storage Requirements of Self-aligning Ball Bearing
》Store indoors, in a frost- and condensation-free environment, at a maximum ambient temperature of 40 °C (105 °F), avoiding air flow.
》Store in vibration-free conditions. Vibration can cause damage to raceways.
》Store horizontally, preferably, to avoid damage that could be caused by the bearing falling over.
》Do not open or damage the original packaging.
Application of Self-aligning Ball Bearing
Airframe and Aircraft Control
Bearings used in airframe and aircraft control are specifically engineered to meet the rigorous requirements of aerospace applications. They come in various designs, including roller, ball, and needle roller configurations.
Aerospace Applications
Ball bearings are specifically engineered for various aerospace applications, including those used in jet engines and helicopters.
Agricultural Machinery
Specialized ball bearings are available for use in agricultural machinery and environments.
Automotive Sector
Bearings designed for the automotive industry are tailored to meet the specific needs of this sector.
Ball Screw Support
Ball bearings used in ball screw applications are often angular contact types with a steep contact angle, such as 60 degrees, and can be configured in duplex, triplex, or quadruplex arrangements. Other designs include bearings with separate radial and thrust rollers in a single assembly and cartridge versions that integrate seals, housings, and bearings.
Miniature and Instrument Bearings
Miniature or instrument ball bearings are compact angular contact or deep groove bearings used in applications requiring very small bearings, such as computer disk drives and dental drills.
Medical or Dental Bearings
These bearings are specifically designed for use in medical and dental equipment, often featuring miniature designs.
Pump Applications
Ball bearings for pump applications are built to withstand harsh conditions, including inadequate lubrication, high loads, and elevated operating temperatures.
Spindle and Super Precision
High-precision ball bearings are used in machine tool spindles, designed for superior accuracy and performance.
Sporting and Consumer Goods
Bearings intended for the sports and consumer goods markets include those used in skateboards, inline skates, and fishing reels.
