Sill Bearing
Sill Bearing
Engineered for high-load durability and long-life performance
The 6004 2RS deep groove ball bearing is one of the most versatile and high-demand components in the modern industrial sector. With its standard dimensions of 20mm x 42mm x 12mm, it serves as the mechanical heartbeat for millions of machines globally. In today's commercial landscape, the 6004 2RS variant, equipped with dual rubber seals (2RS), is favored for its exceptional ability to retain lubricant while providing a formidable barrier against dust, moisture, and particulate contamination. This specific configuration has become the industry standard for manufacturers requiring maintenance-free operation in challenging environments.
From the automated assembly lines in Germany to the burgeoning electric vehicle (EV) plants in Southeast Asia, the 6004 2RS bearing is indispensable. The global market for these bearings is currently driven by the push for energy efficiency and noise reduction. Enterprises worldwide are no longer just looking for "parts"; they are seeking precision-engineered components that reduce friction loss, thereby lowering energy consumption and extending the lifecycle of the end product.
Integration of AI and IoT in production lines to ensure sub-micron accuracy and real-time quality tracking.
Development of high-speed, low-torque bearings specifically designed for the high RPM of electric vehicle motors.
Shifting toward eco-friendly lubricants and recyclable high-grade steel to meet global carbon neutrality goals.
The bearing industry is undergoing a paradigm shift. We are moving away from traditional mass production toward "Smart Manufacturing." As a leading China 6004 2RS bearing factory, we have integrated intelligent monitoring systems that detect even the slightest deviation in material heat treatment or grinding precision. This trend toward "zero-defect" manufacturing is what global procurement officers are now demanding to ensure the reliability of their complex mechanical systems.
Procurement in the 21st century has shifted from a price-centric model to a value-and-stability model. Large-scale distributors in North America and engineering firms in Europe are looking for more than just a 6004 2RS bearing; they are looking for supply chain resilience.
Key procurement requirements include:
Understanding the application is key to selecting the right bearing. The 6004 2RS is a workhorse in numerous sectors:
Used in alternators, starters, and air conditioning compressors where resistance to engine heat and vibration is paramount.
Found in high-end washing machines and power tools, where low-noise (Z3, Z4 levels) is essential for consumer satisfaction.
The backbone of conveyor rollers and robotic joints, requiring long-term reliability under constant operational cycles.
In harsh agricultural environments, the 2RS seals are particularly effective at keeping out soil and moisture, preventing premature failure in harvesters and tractors. Conversely, in the clean-room environments of medical device manufacturing, the 6004 2RS provides a sealed, lubricant-contained solution that prevents contamination of sensitive equipment.
SILL BEARING FACTORY is strategically located in the Hangzhou Bay New Zone, the epicenter of China's advanced manufacturing corridor. Our location isn't just a point on the map; it's a logistics powerhouse.

3. Cost-Efficiency at Scale: By leveraging China's massive industrial supply chain and our own automated production lines, we offer world-class quality at prices that enable our clients to remain competitive in their own markets.
| Attribute | Specification |
|---|---|
| Bore Diameter (d) | 20 mm |
| Outer Diameter (D) | 42 mm |
| Width (B) | 12 mm |
| Sealing Type | 2RS (Rubber Seals on Both Sides) |
| Material | High Carbon Chromium Steel (GCr15) |
The choice of GCr15 steel ensures high fatigue life and excellent wear resistance. Our heat treatment process achieves a Rockwell hardness (HRC) of 60-64, providing the structural integrity needed for high-speed rotations. The "2RS" designation indicates contact rubber seals, which are superior to metal shields (ZZ) in environments where fine particles or liquids are present.
