Introduction about us

The factory was established in 1996, formerly known as Yinsheng Bearing Accessories Processing Department, mainly engaged in the processing of bearing accessories. In 2006, Linqing Special Bearing Factory was established. In order to meet the market demand for bearings, it transformed into a bearing production-oriented company. The customer base is mainly domestic stores and foreign trade company orders. After years of product technology accumulation and sales expansion, in 2024, a company mainly responsible for foreign trade sales was established: Shandong (David) Bearing Manufacturing Co., Ltd.

Now we mainly focus on the production of high-precision bearings and the wholesale business of non-standard bearing customization.

Bearing noise detection

Full Noise Inspection of Bearings: Creating Core Value for Customers

Cost Reduction: It prevents customers from disassembly, replacement and rework due to bearing noise issues after assembly, reduces after-sales maintenance and backup inventory costs, and eliminates hidden losses throughout the entire chain.
Efficiency Improvement: It ensures bearings operate stably once put into use, avoids unplanned production halts, extends the service life of equipment, and helps customers maintain efficient operation of production lines.
Risk Mitigation: It conducts individual inspection to prevent batch quality accidents, meets the noise compliance standards of various industries, and meanwhile protects customers’ brand reputation, solidifying the trust in cooperation.

Classification of deep groove ball bearing sealing covers

White steel sealing cap ZZ

1. Excellent Sealing Performance
A special sealing design effectively isolates gas and liquid leaks, making it suitable for applications requiring a sealed environment, such as sewage treatment tanks and chemical tanks, to prevent the escape of harmful gases and the infiltration of pollutants.

2. Strong Corrosion Resistance
The fiberglass reinforced plastic material is resistant to acids, alkalis, and salt spray, making it suitable for corrosive environments such as chemical and sewage treatment, with a service life of over 10 years.

3. High Load-bearing Capacity
The load-bearing rating meets Class A standards, capable of withstanding the pressure of heavy vehicles or equipment, making it suitable for applications requiring high loads, such as municipal sewage lift pumping stations.

4. Anti-aging and Durable
The surface is treated with a special process to effectively block UV rays and chemical corrosion. It is resistant to fading or cracking with long-term use, and has low maintenance costs.
5. Easy Installation
Customizable sizes and shapes (such as arched and round) are supported, allowing for quick adaptation to various sewage tank structures, making installation simple and efficient.

Yellow iron sealing cap ZZ

Rubber sealing cap 2RS

1. Dust and Waterproof
The rubber sealing cover effectively blocks dust and moisture from entering the bearing, preventing foreign matter from intruding and causing lubricant loss and component wear, while also preventing moisture-induced rust.

2. Maintenance-Free Design
Bearings using rubber seals are typically sealed for life, eliminating the need for regular grease relubrication and simplifying maintenance.

3. Applicability
Rubber seals operate stably in temperatures ranging from -35°C to 165°C, are corrosion-resistant, and offer high ductility, making them particularly suitable for operating conditions requiring frequent starts and stops or varying loads.

4. Noise and Friction Reduction
Compared to metal dust covers, rubber sealing covers offer lower friction, quieter operation, and are suitable for high-speed operation.

Disclosure of non-sealed structure

1. Reduced Friction
Because they lack a seal, uncapped bearings experience relatively low friction, making them suitable for applications requiring high speeds or high loads, such as in automobiles and ships.
2. Improved Lubrication Efficiency
In environments with good lubrication conditions and a clean environment, uncapped bearings provide more complete access to grease or oil, reducing lubricant loss due to the seal structure and maintaining more stable lubrication.
3. Simplified Structural Design
Some coverless bearings (such as motor bearings) can eliminate the need for inner and outer covers, simplifying the assembly process and reducing manufacturing costs. However, it should be noted that this design places high demands on the lubrication system and requires the use of circulating lubricant.
4. Wider Applicability
In environments with low dust levels or good lubrication conditions, coverless bearings offer greater versatility and are particularly suitable for industrial applications requiring frequent disassembly or maintenance.
