Procuring the right bearings can be challenging—with countless models, varying precision classes, and compatibility issues leading to installation delays or unexpected equipment failures. Many buyers face the frustration of mismatched dimensions or substandard materials that cause premature wear, especially in high-speed applications where precision matters most.
Our 6808 series deep groove ball bearings address these challenges with interchangeable dimensions following international standards (DIN, ISO, JIS), ensuring seamless replacement across different equipment brands. As a专业轴承供应商 with ISO 9001 certified production processes, we offer multiple seal options (ZZ, 2RS, Open) to suit your environment—from clean industrial settings to dusty mechanical systems. With现货库存 and low minimum order quantities, we eliminate the long lead times often associated with specialized bearing procurement.
Designed as a non-aligning radial bearing with a 0° contact angle, this 40x52x7 mm bearing excels in applications with primarily radial loads and moderate speeds. Its single-row design and unseparated structure provide stability in power transmission components like small motors and gearboxes, where consistent rotation and minimal vibration (Z1V1 to Z3V3 grades available) are critical for operational efficiency.
The bearing steel construction ensures high surface hardness and wear resistance, directly contributing to longer service life under continuous operation. Precision ratings from P0 to P2 allow selection based on application requirements—P2 for high-precision machinery and P0 for general industrial use. The availability of both grease and oil lubrication options lets you optimize for maintenance intervals: grease for sealed environments requiring less frequent servicing, and oil for high-speed applications where heat dissipation is essential. Additionally, compliance with multiple international standards ensures dimensional consistency when replacing bearings from different manufacturers.
Selecting a bearing that matches your application’s load, speed, and environmental conditions directly impacts total cost of ownership. A bearing with insufficient precision or improper sealing can lead to early failure, causing unplanned downtime, replacement costs, and potential damage to adjacent components. Our 6808 series meets strict quality control standards, including raw material inspection and成品尺寸/硬度 testing, helping prevent these issues. By investing in a bearing that aligns with your equipment’s requirements, you avoid the hidden costs of frequent replacements and maintenance.
All bearings undergo ISO 9001 compliant production and testing processes, from raw material verification to final dimensional and hardness checks. We provide a warranty against manufacturing defects, ensuring you receive bearings that meet specified performance standards. Our ability to supply both自有品牌 and international brand equivalents gives you flexibility in balancing cost and brand preference, while our OEM/ODM services support custom requirements for specialized applications.
Whether you need the 6808, 6808-2RS, or 6808 Rs variant, provide your required seal type, precision class, and quantity, and we’ll deliver a competitive quote with lead time. Our team can also assist with cross-referencing other brands to ensure compatibility with your existing equipment.
Q: Do you supply other bearing brands or models beyond the 6808 series?
A: Yes, we offer a full range of bearings including deep groove ball, roller, and specialized types, and can source international brands (SKF, NSK, NTN, etc.) or domestic equivalents based on your specifications.
Q: How can I confirm if this 6808 bearing fits my equipment?
A: Provide your equipment model or existing bearing dimensions (inner diameter x outer diameter x width), and our technical team will verify compatibility with the 6808 series specifications.
Q: What is your warranty policy for these bearings?
A: We provide a warranty against manufacturing defects. Specific terms are detailed in the sales contract, covering replacement or refund for bearings that fail due to production issues.
Q: What is the minimum order quantity for the 6808 series?
A: We support low minimum order quantities, allowing small batch purchases for maintenance or trial purposes, with volume discounts available for larger orders.
Q: How long does shipping take for in-stock 6808 bearings?
A: In-stock bearings are dispatched within 1-2 business days. Transit time depends on the shipping method: express courier (3-5 days), air freight (5-7 days), or sea freight (20-30 days).
Q: Can you produce custom bearings with modified dimensions or materials?
A: Yes, we offer OEM/ODM services for custom bearing requirements. Provide your technical drawings or specifications, and we can develop a solution tailored to your application.
