Rolling Bearing Vocabulary (1)
A rolling bearing is a type of bearing that allows for rotational motion between two components that support a load and move relative to each other. It typically includes raceway surfaces and rolling elements, which may or may not be enclosed by a cage or guide. These bearings are designed to handle both radial and axial loads, as well as combined loads in those directions.
Angular Contact Bearings: These are rolling bearings where the contact angle between the ball and the raceway is greater than 0° but less than 90°, allowing them to handle significant axial loads in one direction.
Spherical Bearings: These are radial bearings with an outer ring that has a spherical surface, enabling self-alignment. They are often used in applications where misalignment is possible.
Linear Motion Bearings: These bearings allow for linear motion between two raceways. They are commonly used in precision machinery and automation systems.
Ball Bearings: Bearings that use balls as the rolling elements. They are widely used due to their low friction and high-speed capabilities.
Deep Groove Ball Bearings: A common type of ball bearing with grooves on the inner and outer rings that accommodate the balls. They are suitable for both radial and light axial loads.
Thrust Ball Bearings: Designed specifically for handling axial loads. They consist of two washers and a set of balls that roll between them.
Roller Bearings: Bearings that use rollers instead of balls as the rolling elements. They are better suited for heavy radial loads compared to ball bearings.
Cylindrical Roller Bearings: These bearings have cylindrical rollers that are longer than they are wide, making them ideal for high radial loads.
Tapered Roller Bearings: These bearings feature conical rollers that allow them to handle both radial and axial loads simultaneously.
Needle Roller Bearings: These bearings use long, thin rollers that provide a large contact area, making them suitable for compact designs under heavy radial loads.
Spherical Roller Bearings: Self-aligning radial bearings with convex or concave rollers. They can compensate for misalignment and are often used in harsh environments.
Thrust Roller Bearings: Bearings designed to handle axial loads. They include types such as cylindrical, tapered, and needle roller thrust bearings.
Thrust Cylindrical Roller Bearings: These are used to support heavy axial loads in one direction, utilizing cylindrical rollers.
Thrust Tapered Roller Bearings: Similar to standard tapered roller bearings, but designed for axial load applications.
Thrust Needle Roller Bearings: These are compact thrust bearings using needle-shaped rollers, ideal for limited space applications.
Thrust Spherical Roller Bearings: Self-aligning thrust bearings that can handle large axial loads and some radial loads. They are often used in heavy-duty machinery.
Bearing with a Seat: A bearing that is integrated with a housing or seat, providing a convenient mounting solution for various industrial applications.
