Customized Bearing System Solutions: Design, Composition, and Solutions
In the efficient operation of industrial equipment, customized bearing system solutions are a key element in improving mechanical performance and extending service life. This article will discuss the design of bearing system solutions, the composition of bearing systems, design processes, and solutions, combining industry practices and technical requirements to provide professional references for engineers and decision-makers.
1. Key Elements of Bearing System Solution Design
A customized bearing system needs to comprehensively consider core parameters such as working conditions, load characteristics, and service life. For example, in high-temperature, high-pressure film production lines (such as BOPET, lithium battery separator production lines), corrosion-resistant and wear-resistant alloy or ceramic bearings should be selected, and structural design should be optimized to reduce frictional heat and improve rotational precision.
| Material Selection | 45 steel with quenching and tempering treatment is suitable for general conditions, while stainless steel or ceramic bearings should be used in special environments (e.g., corrosive media). |
|---|---|
| Lubrication System | Choose grease or lubricating oil according to temperature and load, and equip with automatic grease replenishing functions to ensure lubrication stability during continuous production. |
| Sealing Design | Use multi-layer sealing structures (such as felt seals or mechanical seals) to prevent contamination and extend bearing life. |
2. Main Components of Bearing System
A complete bearing system consists of the following core components:
| Bearing Body | Includes types such as deep groove ball bearings, angular contact bearings, etc., selected based on axial force and speed requirements (e.g., 6200, 6300 series). |
|---|---|
| Support Structure | Bearing housings, end caps, and oil shields, which need to meet installation precision and sealing requirements. |
| Auxiliary Systems | Lubrication devices, temperature monitoring sensors (such as strain sensors) for real-time status monitoring and fault early warning. |
| Transmission Connectors | Couplings, keyways, etc., to ensure reliable power transmission and alignment. |
3. General Process for Bearing Design
Taking mechanical drive shaft design as an example, the process can be divided into the following steps:
| Requirement Analysis | Clarify parameters such as load, speed, working environment (e.g., cleanliness, temperature rise). |
|---|---|
| Material and Initial Shaft Diameter Calculation | Calculate the minimum shaft diameter using the torsional strength formula (e.g., for 45 steel, C value is 112) and adjust the size according to keyway influence. |
| Structural Design | Design the diameters and lengths of each section of the stepped shaft, and determine installation positions and fixation methods based on bearing types (e.g., 6207 deep groove ball bearings). |
| Strength Check | Verify the shaft’s fatigue resistance and deformation resistance through force analysis, bending moment diagrams, and safety factor calculations. |
| Life Assessment | Verify bearing life based on the equivalent dynamic load formula to ensure it meets the service life of the equipment (e.g., 3 years of 3-shift operation). |
4. Industry Customized Bearing Solution Cases
| Film Production Lines | For high-temperature and high-pressure environments in BOPP, BOPET, and other production lines, ceramic bearings with automatic lubrication systems are used to reduce downtime maintenance frequency. |
|---|---|
| New Energy Equipment | Bearings for lithium battery separator production lines need to have both corrosion resistance and high-speed characteristics, paired with grease lubrication and dust-proof sealing design. |
| Heavy Machinery | In belt conveyor shaft design, couplings compensate for installation errors, and key connections are optimized to withstand shock loads. |

1What are Micro Bearings?
"Drone out of control and crashing? 90% chance it's not user error, but rather this bearing smaller than a fingernail causing the issue!" This is a micro bearing.
