Many buyers face challenges when sourcing deep groove ball bearings—whether it’s matching the right seal type for harsh environments, finding precise dimensions across different standards, or dealing with frequent replacements due to poor quality. The NSK NTN 6201-6220 Zz 2RS DDU series addresses these issues with interchangeable dimensions and reliable performance.
This deep groove ball bearing series offers multiple seal options (Zz, 2RS, Open) to suit various operating conditions, from clean industrial settings to dusty or moist environments. With precision ratings from P0 to P2, it meets the needs of both general machinery and high-precision equipment. Our ISO 9001 certified processes ensure consistent quality, and we maintain extensive stock to support quick delivery for urgent maintenance or production needs.
These bearings excel in radial load applications with operating speeds suitable for electric motors, pumps, and conveyor systems. The 0° contact angle ensures efficient radial load distribution, while the single-row design provides compact installation where space is limited. Available vibration grades (Z1V1 to Z3V3) allow selection based on noise and smoothness requirements, critical for precision automation equipment.
The bearing steel construction delivers high surface hardness and wear resistance, essential for withstanding continuous operation under load. Precision ratings directly affect rotational accuracy—P5 and P4 grades reduce runout, minimizing vibration in high-speed applications. Sealed variants (2RS) retain lubrication and exclude contaminants, extending maintenance intervals compared to open bearings. The unseparated design simplifies installation and ensures consistent performance during assembly.
Selecting a bearing with appropriate precision and seal type reduces the risk of premature failure, which can lead to unplanned downtime and costly repairs. For example, using a 2RS sealed bearing in dusty environments prevents particle ingress that would otherwise cause abrasive wear. Proper lubrication (grease or oil) selection, based on operating temperature and speed, further extends service life. While initial costs may vary by specification, the long-term savings from reduced maintenance and replacement often outweigh the difference.
Our production and inspection processes adhere to ISO 9001 standards, with raw material verification and成品尺寸、硬度及表面处理检测. We provide a warranty period covering manufacturing defects, ensuring peace of mind for your purchase. With access to both international brands (including NSK, NTN) and domestic quality options, we can source bearings to your exact specifications, whether you need a direct replacement or a custom solution.
Whether you need a specific model from the 6201-6220 range or require assistance in selecting the right bearing for your application, we’re here to help. Provide your required model number, dimensions (d x D x B), and quantity, and our team will quickly respond with pricing and availability. The sooner you confirm your order, the sooner we can arrange shipment to keep your operations running smoothly.
Q: Do you supply bearings from other brands besides NSK and NTN?
A: Yes, we offer a wide range of bearing brands including SKF, Koyo, NACHI, IKO, FAG, Timken, and domestic quality brands. We can source bearings according to your specified brand and model requirements.
Q: How can I confirm if this bearing fits my equipment?
A: Provide your equipment’s required bearing dimensions (inner diameter d, outer diameter D, width B), model number, or application details. Our technical team will verify compatibility with the 6201-6220 series specifications.
Q: What is your warranty policy for these bearings?
A: We provide a warranty period covering manufacturing defects. Specific terms and duration are detailed in each sales contract, ensuring coverage for any quality issues arising from production.
Q: What is the minimum order quantity for this bearing series?
A: We support low minimum order quantities, allowing you to purchase small volumes for testing or emergency replacements, as well as bulk orders for production needs.
Q: How long does shipping take, and what delivery methods are available?
A: In-stock bearings are shipped immediately. Delivery time depends on your location and chosen method: courier (3-7 days), air freight (5-10 days), or sea freight (20-40 days). We’ll recommend the most cost-effective option based on your timeline.
Q: Can you provide OEM or ODM customized bearings?
A: Yes, we support OEM and ODM services. If you need bearings with specific dimensions, materials, or branding, provide your technical drawings or specifications, and we can produce custom solutions.
