Finding the right bearing for your equipment can be challenging, especially when dealing with multiple brands and complex specifications. Many buyers face issues like mismatched dimensions leading to installation delays or premature failure due to poor material quality. Sourcing from different suppliers also means juggling multiple lead times and price comparisons, wasting valuable time.
This Koyo cylindrical roller bearing series addresses these challenges with its adherence to international standards and compatibility with major brand dimensions. Produced under ISO 9001 certified processes, it ensures reliable performance in industrial machinery, automation systems, and mechanical engineering applications. Our extensive inventory covers both this series and its deep groove ball bearing counterparts, allowing for one-stop sourcing and reduced procurement complexity.
Designed specifically for radial load applications, this single-row cylindrical roller bearing operates efficiently under continuous radial stress. Its bearing steel construction provides excellent durability, making it suitable for moderate-speed machinery such as conveyor systems and electric motors. The open, Zz, and 2RS seal options accommodate different contamination levels, from clean industrial environments to those with moderate dust exposure.
The 8*22*7 mm specification ensures precise fitting in standard equipment housings, while the P0-P2 precision ratings allow selection based on application accuracy requirements—from general industrial use (P0) to high-precision machinery (P2). Vibration classes Z1V1 to Z3V3 provide options for noise-sensitive applications, with higher classes reducing operational sound levels. The dual lubrication capability (grease or oil) offers flexibility based on operating temperature and speed, with grease suitable for most standard conditions and oil recommended for high-temperature environments.
Selecting a bearing that matches both load requirements and operating conditions directly impacts equipment uptime and maintenance costs. A properly specified bearing reduces the risk of early failure, which can cause costly production downtime and damage to adjacent components. This series’ robust construction and material quality contribute to longer service life, reducing replacement frequency and overall maintenance expenses. By choosing a bearing that meets your exact precision and vibration needs, you avoid over-specifying (which increases initial cost) or under-specifying (which leads to premature failure).
Our bearings undergo strict quality control processes, including raw material inspection and成品尺寸、硬度及表面处理检测. We provide a warranty period covering manufacturing defects, ensuring you receive reliable products. With access to both international brands like Koyo and domestic优质品牌, we can source according to your specific brand or standard requirements. Our现货库存 allows for quick order fulfillment, supporting your production schedules with minimal lead time.
Whether you need the N217em, N218em, N219em series or other bearing types, provide your required model, dimensions, and quantity, and we’ll deliver a competitive quote. Our team can also assist with cross-referencing part numbers across different brands to ensure compatibility with your equipment. The sooner you confirm your requirements, the faster we can arrange shipment.
Q: Do you supply bearings from other brands besides Koyo?
A: Yes, we offer a full range of bearings from international brands including SKF, NSK, NTN, NACHI, IKO, FAG, Timken as well as domestic优质品牌. We can source according to your specified brand or model.
Q: How can I confirm if this bearing fits my equipment?
A: Provide your equipment model or existing bearing dimensions (bore diameter, outer diameter, width), and our technical team will verify compatibility with the Koyo N217em-N219em series.
Q: What is your warranty policy for these bearings?
A: We provide a warranty period covering manufacturing defects. Specific terms are detailed in our sales contract, and defective products can be replaced or returned within the warranty period.
Q: What is the minimum order quantity for this bearing series?
A: We support low minimum order quantities, including small trial orders, to meet both your immediate needs and larger production requirements.
Q: How long does shipping take, and what methods are available?
A: Stock items ship immediately. Delivery time depends on your location—courier for urgent orders (3-5 days), air freight (5-7 days), or sea freight (3-4 weeks). We’ll recommend the most cost-effective option based on your timeline.
Q: Can you provide OEM or ODM services for bearings?
A: Yes, we support OEM and ODM customization according to your drawings, specifications, or sample requirements for both standard and non-standard bearings.
