Deep Groove Ball Bearing

Deep groove ball bearings are among the most commonly used bearing types due to their versatility and reliability. Their design features a deep raceway that allows them to accommodate high radial loads and some axial loads in both directions. They are suitable for a wide range of B2B applications, including automotive components and industrial machinery. When purchasing, buyers should consider the load ratings and lubrication options to ensure optimal performance in their specific application.

Angular Contact Ball Bearing

Angular contact ball bearings are engineered to support both radial and axial loads, making them ideal for applications that require high-speed and precision. The contact angle of the balls allows for higher load capacities compared to deep groove bearings. They are frequently used in robotics, aerospace, and high-speed machinery. Buyers should take note of the installation requirements and alignment precision, as improper setup can lead to premature failure.

Self-Aligning Ball Bearing

Self-aligning ball bearings feature a spherical outer race that enables them to compensate for shaft misalignment. This characteristic makes them particularly useful in applications where alignment may be an issue, such as agricultural machinery and conveyor systems. While they provide excellent performance in misaligned conditions, buyers should be aware that their load capacity is generally lower than other bearing types, making them less suitable for heavy-duty applications.

Tapered Roller Bearing

Tapered roller bearings are designed to handle significant radial and axial loads, making them a popular choice in heavy machinery and automotive applications. Their conical shape allows for efficient load distribution, providing high durability and performance. However, proper mounting and alignment are critical for their functionality. Buyers should consider the specific load requirements and ensure that they have the necessary infrastructure for correct installation.

Thrust Ball Bearing

Thrust ball bearings are specifically designed to handle axial loads, featuring two or more rows of balls that provide efficient load distribution. They are commonly used in marine applications and machine tool spindles, where axial forces are prevalent.
