Radial Bearings

Radial bearings are engineered to support loads that act perpendicular to the shaft. Their cylindrical shape allows them to handle both radial and some axial loads. Commonly used in electric motors and automotive applications, these bearings are favored for their high load capacity and versatility. When purchasing, consider factors such as load ratings, speed capabilities, and the alignment of the installation, as misalignment can significantly affect performance and lifespan.

Thrust Bearings

Thrust bearings are specifically designed to manage axial loads, making them essential in applications where forces act along the shaft’s axis. These bearings typically feature a flat surface and are frequently employed in gearboxes, turbines, and pumps. Buyers should focus on the bearing’s load rating and material, as these factors influence durability and efficiency. While they excel in axial load handling, thrust bearings have limitations in handling radial loads, which should be considered during selection.

Spherical Bearings

Spherical bearings are unique for their ability to accommodate angular misalignment, thanks to their spherical outer surface. This characteristic makes them ideal for use in agricultural machinery and construction equipment, where alignment can be challenging. When purchasing spherical bearings, it is crucial to evaluate the misalignment tolerance and lubrication requirements. While they offer flexibility, the more complex design can lead to higher costs compared to standard bearings.

Angular Contact Bearings

Angular contact bearings are designed to handle both radial and axial loads simultaneously, making them suitable for high-speed and precision applications such as aerospace and robotics. The angular contact angle allows for efficient load distribution, but it also necessitates precise installation to achieve optimal performance. Buyers should pay attention to the bearing’s preload and lubrication type to ensure longevity and reliability in demanding environments.

Plain Bearings

Plain bearings, also known as bushings, are among the simplest bearing types, consisting of a sleeve that supports the shaft. Often made from bronze or plastic, they are cost-effective and easy to maintain, making them suitable for general machinery and conveyor systems. However, buyers should be aware of their limitations in terms of load capacity and speed, as they typically perform best in low-speed applications. Proper lubrication and material selection are vital for maximizing their performance and lifespan.
