Welcome to Henan San Kuang Machinery Technology Co., Ltd. – your trusted partner in precision bearing solutions. Since 2014, we have been dedicated to manufacturing high-quality bearings from our 10,000-30,000 square meter facility in Luoyang, China. Our Precision Bearing 6205-2RS is a reliable deep groove ball bearing designed for demanding applications. It comes with a 1-year warranty and a Mill Test Report to ensure full traceability and quality assurance. Whether you need replacement bearings for industrial machinery or OEM components, this product delivers consistent performance and durability.
This bearing features double rubber seals (2RS) on both sides, providing excellent protection against dust, moisture, and contaminants. The seals are made of high-quality nitrile rubber (NBR), which offers good resistance to oil and grease while maintaining low friction. The bearing is pre-lubricated with lithium-based grease, ensuring smooth operation from the moment of installation. With a standard clearance of C0 (C3 available upon request), it can accommodate various thermal expansion and operating conditions.
The 6205-2RS is manufactured from high-grade chrome steel (GCr15) with a hardness of HRC 60-65, ensuring long service life and wear resistance. The raceways are precision ground and polished to ABEC-1 / P0 tolerance, guaranteeing low noise, low vibration, and high rotational accuracy. Each bearing undergoes strict quality control during production, and the Mill Test Report provides detailed dimensional and material data for your verification.

Frequently Asked Questions
Q1: What is the difference between 6205-2RS and 6205-ZZ?
A: 6205-2RS has double rubber seals (contact seals) on both sides, providing better protection against contaminants and retaining lubricant. 6205-ZZ has metal shields (non-contact) which offer less sealing but lower friction. The 2RS version is ideal for dirty or moist environments.
Q2: Can I use this bearing for high-speed applications?
A: The limiting speed of 6205-2RS with grease lubrication is 12,000 rpm. For higher speeds, oil lubrication is recommended (up to 15,000 rpm). If your application exceeds these limits, please contact us for alternative options.
Q3: Is the Mill Test Report issued for every bearing?
A: Yes, each bearing comes with a Mill Test Report that covers the raw material batch. It includes chemical composition, hardness, and dimensional data. This report is provided as a standard document.
Q4: Does the bearing require initial lubrication?
A: No, the bearing is pre-lubricated with high-quality lithium grease. It is ready to use out of the box. However, if you have specific grease requirements, we can customize the lubrication upon request.
Q5: What is the warranty coverage?
A: The 1-year warranty covers manufacturing defects such as material flaws, abnormal noise, or premature failure under normal operating conditions. It does not cover damage due to misuse, improper installation, or external factors.
Q6: Can I get a sample before placing a bulk order?
A: Yes, we offer samples for testing. Please contact our sales team to arrange a sample order. Shipping costs may apply depending on the quantity.
Q7: What packaging options are available?
A: Standard packaging includes individual poly bags, then a cardboard box, and finally a plywood pallet for export. Custom packaging with your logo or special labeling is available upon request.
Q8: Which ports do you ship from?
A: We ship from Shanghai, Lianyungang, Qingdao, and Tianjin ports. We can also arrange door-to-door delivery for certain destinations.
