NF Series Cylindrical Roller Bearings: Engineered for High Radial Loads
Shanghai Yinin Bearing & Transmission Company is a wholesale NF Series cylindrical roller bearings manufacturer and supplier. With over 20 years in the bearing industry, we supply NF200, NF2200, and NF300 series bearings designed for applications requiring high radial load capacity and stiffness. Our integrated sales and manufacturing group ensures consistent quality and supply for global OEMs, distributors, and plant maintenance teams.
NF series bearings feature cylindrical rollers guided by a cage, providing excellent load distribution and low friction. They are ideal for gearboxes, electric motors, pumps, and other rotating machinery where radial loads dominate. Our range covers a wide spectrum of bore sizes, with options for different cages and tolerances to suit specific operating conditions.
Key Series: NF200, NF2200, NF300 – each designed for specific load and speed requirements.

Engineering Value and Customization
Our engineering team works with you to select the correct bearing based on load calculations, speed, and mounting arrangement. We offer customized non-standard bearings for unique applications, including modified internal clearances, special materials, and coatings.
- Custom bore and outer diameter tolerances
- Special cage materials for high-temperature environments
- Enhanced corrosion resistance for washdown or marine applications
- Precision grades for machine tool spindles
Quality Assurance and Testing
We implement inspections at every production stage, from raw material to finished bearing. Final products undergo full inspection according to customer requirements and international standards, ensuring dimensional accuracy and running noise compliance.
Our factory in Jiangsu Province is equipped with modern manufacturing and precision measuring instruments. We maintain a separate QC center to verify quality before shipment.
Integration and Support
We provide technical documentation, mounting instructions, and after-sales support. Our team assists with installation guidance and troubleshooting to ensure optimal bearing performance.
Information We Use to Configure Your Solution
To prepare a precise quotation and configuration, please provide:
- Bearing series and bore size (e.g., NF206)
- Operating load (radial and axial) and speed
- Mounting arrangement (shaft and housing fit)
- Environmental conditions (temperature, contamination, lubrication)
- Required precision class and cage type
- Annual quantity and delivery schedule
FAQs
What is the difference between NF and NU series?
NF bearings have flanges on both rings, allowing axial location in one direction, while NU bearings have flanges only on the outer ring, permitting free axial displacement. Choose NF when axial positioning is required.
Can you supply NF bearings with special tolerances?
Yes, we can manufacture to P6, P5, or P4 precision classes upon request. Our engineering team will confirm feasibility based on the specific series and size.
What is the minimum order quantity?
Our MOQ is typically 100 sets for standard sizes, but we can accommodate smaller trial orders for evaluation. Contact us to discuss your needs.
How do you ensure bearing quality before shipment?
We conduct 100% inspection on critical dimensions and noise levels for each batch. Our QC reports are available upon request.
Do you provide technical support for bearing selection?
Yes, our technical team can assist with load calculations and application engineering. Share your operating conditions, and we will recommend the optimal bearing.
