The Crucial Role of Bearings in Different Industrial Operations
Bearings by Category
Mounted Units
Mounted bearings units are encased in a housing that can be bolted onto a machine. They support spinning shafts and handle radial and axial loads, simplifying installation and enhancing performance.
Cam Followers
A cam follower is a special roller or needle bearing that tracks cam lobe profiles. It is mounted using either a stud or a yoke-style hole, enabling it to accommodate the cam’s back-and-forth or swinging motion.
Ball Bearings
A ball bearing, also known as a rolling-element bearing, utilizes balls to keep the bearing races separated. A cage in these bearings ensures uniform load distribution and minimizes rotational friction.
Linear
Linear bearings are specialized mechanical components that facilitate unidirectional motion along a straight path, reducing friction in motion systems where the movement occurs linearly. They differ from radial bearings.
Double Row
Double Row Angular Contact Ball Bearings can handle the radial, moment, and bidirectional axial loads. They are constructed like two single-row angular ball bearings mounted back to back.
Deep Groove
Deep Groove ball bearings are known for their seal, shield, and snap-ring configurations and can withstand radial, axial, or composite loads while allowing for high-running precision.
Ball Screw
These bearings are ball screw support bearings with high axial rigidity and sealed design. They do not require maintenance and come pre-equipped with high-performance lubrication grease.
Combination Angular
Single-Row Angular Contact Ball bearings are typically used in combinations of two or more bearings. These combinations can be in a DB (back-to-back), DF (face-to- face), or DT (tandem).

Common Bearings & Their Use Cases
You can find bearings in many shapes and sizes. Each type has a particular function and supports a particular type of load. The most common industrial bearings are given below:
-
1
Ball Bearings:
These bearings reduce friction between moving parts, enabling smooth rotary motion and supporting both radial and axial loads effectively in various machinery applications.
-
2
Roller Bearings:
Designed to handle higher load capacities than ball bearings, roller bearings use cylindrical rollers to distribute weight over a larger surface area. This results in improved load capacity and stability.
-
3
Spherical Plain Bearings:
These allow for angular rotation in all directions between two parts while keeping a low friction interface. Thus, they are suitable for applications requiring misalignment compensation.
-
4
Mounted Bearings:
Typically housed units that support rotating shafts, mounted bearings simplify installation and alignment. They are mounted directly onto the machine frame to protect against contaminants in harsh environments.
-
5
Plain Bearings:
Plain bearings or bushings provide a sliding surface for motion without rolling elements. They are for low-speed uses where simplicity and cost-effectiveness are your priorities.
-
6
Cam Roller Bearings:
They accommodate cam profiles in applications like conveyor systems. These bearings cause low friction and result in high load capacity.
-
7
Cam Rollers:
Often used in conjunction with cam roller bearings, these components enable precise movement in machinery by following the contour of a cam, ensuring efficient operation in automated systems.
