Many buyers struggle with mismatched bearing dimensions causing installation delays, or low-quality bearings failing prematurely with excessive noise and vibration. Sourcing from multiple suppliers for different brands also wastes valuable time comparing prices and lead times.
Our deep groove ball bearings solve these challenges through ISO 9001 certified manufacturing processes and comprehensive quality testing. With access to both international brands like NTN and domestic manufacturers, we provide a single-source solution for your bearing needs. Whether for high-speed electric motors or heavy-duty industrial machinery, these bearings deliver reliable radial load support with minimal maintenance requirements.
Designed with a contact angle of 0°, this deep groove ball bearing excels in applications with primarily radial loads. Its single-row design ensures compact installation where space is limited, while the bearing steel construction provides durability in operating temperatures from -30°C to 120°C. The 120mm bore diameter and 170mm outer diameter make it suitable for medium-sized shafts in conveyor systems and machine tool assemblies.
The precision 28mm width ensures proper load distribution across the races, reducing stress concentrations that lead to premature failure. Bearing steel material offers superior hardness (HRC 58-62) and fatigue resistance compared to carbon steel alternatives, extending service life in high-cycle applications. The 0° contact angle design minimizes axial thrust, making it ideal for equipment with minimal axial movement. Dimensional accuracy (ISO class P0) guarantees interchangeability with major international standards, simplifying replacement and reducing inventory costs.
Investing in quality deep groove ball bearings reduces overall operating costs by minimizing downtime from unexpected failures. Inferior bearings often show early signs of wear within 3-6 months, requiring costly replacements and production interruptions. Our bearings, manufactured to strict dimensional and hardness standards, typically achieve 2-3 times longer service life in comparable applications. Properly selected bearings also reduce energy consumption by maintaining consistent friction levels, contributing to lower electricity costs over time.
Our production and inspection processes are ISO 9001 certified, ensuring consistent quality from raw material selection to final product testing. Each bearing undergoes dimensional checks for bore, outer diameter, and width, as well as hardness testing to verify material properties. We provide a standard质保期 against manufacturing defects, with clear terms outlined in each sales contract. With access to a wide range of brands including SKF, NSK, Koyo, and NACHI, we can source bearings according to your specific brand preferences. Our extensive inventory allows for quick turnaround on most standard sizes, supporting your production schedules with minimal lead time.
Provide your required bearing model, quantity, and delivery location, and our team will promptly send you a competitive quote. We handle all major brands and can source specific models according to your technical specifications. Early order confirmation ensures priority processing and faster delivery.
Q: Do you supply bearings from other brands besides NTN?
A: Yes, we support inquiries for all major bearing brands including SKF, NSK, Koyo, NACHI, IKO, FAG, Timken, and domestic Chinese brands, providing a comprehensive sourcing solution.
Q: How can I confirm if this bearing fits my equipment?
A: Provide your equipment model or existing bearing dimensions (bore diameter x outer diameter x width), and our technical team will verify compatibility with the 6217 series specifications.
Q: What is your warranty policy for these bearings?
A: We offer a standard质保期 against manufacturing defects. Specific warranty terms and duration are detailed in each sales contract and may vary based on application requirements.
Q: What is the minimum order quantity for this bearing?
A: We maintain low minimum order quantities to accommodate both small-scale repairs and large production runs. Contact us with your specific requirements for exact MOQ information.
Q: How quickly can you ship after order confirmation?
A: Most standard bearings are in stock and ship within 1-3 business days. Shipping time depends on your location and chosen logistics method (express, air, or sea freight).
Q: Do you offer OEM or ODM services for custom bearings?
A: Yes, we support custom bearing manufacturing (OEM/ODM) based on customer-provided drawings, specifications, or sample parts for specialized applications.
