Hengshui Ruibin New Materials LLC, a professional manufacturer founded in 2019 with a factory size of 1,000-3,000 square meters and over 100 employees, proudly presents the Rubber Bearing 6204-2RS. This bearing is engineered to deliver exceptional performance in conveyor systems, combining noise reduction, low friction, and a compact 20mm inner diameter. Designed for long-lasting operation, it meets the demanding requirements of material handling and automation equipment. Our rigorous quality control and annual export value of US$2.5-5 million demonstrate our commitment to reliable and competitive products.
Key Features and Benefits
- Noise Reduction Technology: The rubber seals and precision raceway geometry minimize vibration and sound, ideal for noise-sensitive environments like warehouses or food processing lines.
- Low Friction Design: High-quality steel balls and optimized lubrication reduce rotational resistance, saving energy and extending conveyor belt life.
- 20mm Inner Diameter: Standard size fits many conveyor rollers and pulley systems, ensuring easy replacement or integration.
- 2RS Rubber Seals: Dual-lip rubber seals protect against dust, moisture, and contaminants, enhancing durability in harsh industrial conditions.
- High Load Capacity: Supports both radial and axial loads common in conveyor systems, with dynamic load rating ~12.8 kN and static load rating ~6.6 kN.

Detailed Advantages for Conveyor Systems
Our rubber bearing is specifically designed for conveyor applications where smooth, quiet operation is critical. The low-friction design reduces heat generation, allowing for longer maintenance intervals and lower energy consumption. The rubber seals provide excellent protection against dust and debris common in conveyor environments, such as grain, packaging materials, or metal shavings. The bearing's compact size (20mm ID) fits standard conveyor rollers, making it a direct replacement for many OEM parts. Additionally, the noise reduction feature helps create a safer and more comfortable working environment, especially in automated facilities where multiple bearings operate simultaneously.
Quality Assurance and Trust
As a manufacturer based in Hengshui, Hebei, China, we have established a 1,000-3,000 sqm production facility with 101-200 skilled employees. Our annual export value of US$2.5-5 million reflects our strong presence in global markets including North America, South America, Eastern Europe, Southeast Asia, Africa, Oceania, and more. We ship from Port of Tianjin and Port of Qingdao, ensuring timely delivery worldwide. Every bearing undergoes strict quality checks to ensure consistent dimensions, noise levels, and load capacity.

Frequently Asked Questions
-
Q: What is the difference between 6204-2RS and 6204-ZZ?
A: The 6204-2RS has rubber seals on both sides, providing better protection against dust and moisture than metal shields (ZZ). It is ideal for conveyor systems where contaminants are present. -
Q: Can this bearing be used in high-temperature environments?
A: The standard rubber seal (NBR) is suitable for temperatures from -30°C to +120°C. For higher temperatures, we can provide optional seals (e.g., Viton) upon request. -
Q: What is the typical lifespan of this bearing in a conveyor application?
A: With proper lubrication and maintenance, the service life can exceed 10,000 hours under normal load and speed conditions. Actual lifespan depends on operating conditions. -
Q: Is the bearing pre-lubricated?
A: Yes, each bearing is pre-greased with high-quality lithium-based grease. Custom grease types are available on request. -
Q: Can I get samples before bulk order?
A: We offer sample orders for testing. Please contact us for sample availability and shipping costs. -
Q: What is the minimum order quantity (MOQ)?
A: MOQ is typically 100 pieces for standard models, but we can accommodate smaller quantities for trial purposes. -
Q: How do you ensure the noise reduction performance?
A: We use precision-grade steel balls and controlled raceway finishing. Each bearing is tested for noise level during production to ensure ≤30 dB. -
Q: What packaging options are available?
A: Standard packaging includes individual poly bags and then export cartons. Custom packaging (blister, tube, etc.) is available upon request.
