14 Types of Bearings and Their Applications

Comprehensive Overview of Bearings in Machinery

Bearings are indispensable components in machinery and equipment, playing a pivotal role in supporting rotating mechanical bodies. Their primary function is to decrease the friction coefficient during transmission and reduce the mechanical load, thereby enhancing the efficiency and longevity of the equipment.

Classification of Bearings

Bearings can be categorized based on several factors, each influencing their design, application, and performance. Below are the primary classification criteria:

1. Direction of Load or Nominal Contact Angle

• Radial Bearings: These bearings are designed to support loads perpendicular to the axis of rotation. They are commonly used in applications where the primary load is radial.
• Thrust Bearings: These bearings support loads parallel to the axis of rotation. They are ideal for applications where axial loads are predominant.

2. Type of Rolling Element

• Ball Bearings: These bearings use spherical rolling elements. They are suitable for applications requiring low friction and high-speed operation but are less capable of handling heavy loads compared to roller bearings.
• Roller Bearings: These bearings use cylindrical, tapered, or spherical rolling elements. They are designed to handle heavier loads and can accommodate both radial and axial loads, depending on their design.

3. Ability to Align

• Aligning Bearings: These bearings can accommodate misalignment between the shaft and the housing. They are ideal for applications where shaft deflection or misalignment is expected.
• Non-Aligning (Rigid) Bearings: These bearings do not compensate for misalignment and require precise alignment during installation.

4. Number of Rows of Rolling Elements

• Single-Row Bearings: These bearings have a single row of rolling elements. They are commonly used in applications with moderate loads and speeds.
• Double-Row Bearings: These bearings have two rows of rolling elements, providing higher load-carrying capacity and greater rigidity.
• Multi-Row Bearings: These bearings have more than two rows of rolling elements, offering even higher load capacities and stiffness.

5. Separability

• Separable Bearings: These bearings have components that can be separated for easy installation, maintenance, and replacement.
• Non-Separable Bearings: These bearings are designed as a single unit and cannot be disassembled.

6. Structure Shape and Size

Bearings also vary in their structural shape and size, which can be tailored to specific applications and operational requirements.

Focus on 14 Common Types of Bearings

This article will delve into the features, differences, and appropriate applications of 14 common types of bearings. Understanding these distinctions is crucial for selecting the right bearing for specific machinery and equipment needs, ensuring optimal performance and durability.

1. Angular Contact Ball Bearing

Angular contact ball bearings are designed to handle both radial and axial loads. The contact angle between the ferrule (raceway) and the ball is a critical factor in determining the bearing’s performance characteristics. Standard contact angles are typically 15°, 30°, and 40°. Each angle provides different load-handling capabilities:

• 15° Contact Angle: Suited for high-speed applications due to lower axial load capacity.
• 30° Contact Angle: Offers a balance between axial load capacity and speed.
• 40° Contact Angle: Provides the highest axial load capacity but is less suited for high-speed applications.

Single-Row Bearings

A single-row angular contact ball bearing can support both radial loads and unidirectional axial loads. The unique design of these bearings allows them to handle combined loads (both radial and axial) simultaneously. However, they are typically used in applications where the axial load is in one direction.

Double-Row Bearings

By combining two single-row angular contact ball bearings on the same axis, the structure can support both radial and bidirectional axial loads. This configuration shares the inner and outer rings between the two bearings, resulting in a more robust and versatile solution.
