Many buyers struggle with mismatched bearing dimensions causing installation delays, or low-quality bearings failing prematurely under radial loads. Sourcing from multiple suppliers for different brands also wastes valuable time comparing prices and lead times.
This cylindrical roller bearing addresses these challenges with ISO 9001-certified production processes and dimensions compatible with major international standards. Our extensive inventory covers both Koyo models and alternatives, ensuring you get the right bearing without unnecessary delays—whether for工程机械 gearboxes or steel mill conveyors.
Designed specifically for radial load applications, this bearing excels in high-speed rotating environments where precision matters. Its single-row configuration balances load capacity with compact design, making it ideal for equipment with space constraints but requiring reliable operation under continuous radial stress.
The bearing steel construction provides excellent hardness and wear resistance, critical for withstanding the demands of industrial machinery. Available precision ratings from P0 to P2 ensure compatibility with everything from general-purpose equipment to high-precision automation systems. Sealing options (Zz, 2RS, Open) allow customization based on environmental conditions—whether you need protection from contaminants or prefer maintenance-free operation with grease lubrication.
Selecting a bearing with proper precision and load capacity directly impacts equipment uptime. A bearing that matches your application’s radial load requirements avoids premature failure, reducing downtime for replacements and repairs. While initial costs matter, the long-term savings from fewer failures and maintenance interventions make quality bearings a sound investment.
Our manufacturing and inspection processes adhere to ISO 9001 standards, with rigorous testing of raw materials and finished products for dimensional accuracy, hardness, and surface quality. We provide a warranty against manufacturing defects, ensuring you receive bearings that meet specifications. With access to both international brands and domestic alternatives, we can source the exact bearing you need—whether by model number, dimensions, or performance requirements.
Whether you need N220em, N221em, N222em, or any other cylindrical roller bearing model, provide us with your requirements—quantity, dimensions, and application details—and we’ll deliver a competitive quote with lead time information. The sooner you confirm, the sooner we can arrange shipment.
Q: Do you supply bearings from other brands besides Koyo?
A: Yes, we support inquiries for all major international and domestic brands, providing options based on your specifications and budget.
Q: How can I confirm if this bearing fits my equipment?
A: Provide your equipment model or existing bearing dimensions (inner diameter, outer diameter, width), and our technical team will verify compatibility.
Q: What warranty do you offer on bearings?
A: We provide a warranty against manufacturing defects; specific terms are detailed in our sales contract.
Q: What is the minimum order quantity?
A: We accept low minimum orders, including single units for emergency repairs and bulk quantities for production lines.
Q: How quickly can you ship after ordering?
A: In-stock items ship within 1-2 business days; shipping time depends on your location and chosen logistics method.
Q: Can you produce custom bearings to my specifications?
A: Yes, we offer OEM/ODM services for custom bearing designs, including material selection and special dimensions.
