Stop Production Delays with Genuine SKF NN 3017 KTN9/UP Double Row Cylindrical Roller Bearing
Maintenance teams across industrial sectors face recurring challenges: unexpected equipment downtime from premature bearing failure, long lead times for critical components, and the complexity of sourcing multiple bearing brands from different suppliers. When a machine tool spindle or conveyor system grinds to a halt, every hour of delay translates to lost productivity and mounting repair costs.
Original SKF Quality, Available for Immediate Shipment
The SKF NN 3017 KTN9/UP Double Row Cylindrical Roller Bearing addresses these pain points with factory-certified performance and reliable availability. As an official SKF distributor, we maintain centralized inventory of this industrial machinery bearing, enabling same-day processing for urgent orders. Designed for precision applications like CNC machine spindles and heavy-duty gearboxes, this bearing delivers consistent load distribution and high radial rigidity—critical for maintaining production accuracy and reducing unplanned downtime.
Engineered for High-Performance Industrial Environments
This double row cylindrical roller bearing excels in applications requiring precise axial guidance and high radial load capacity. Its open design allows for lubrication customization to suit specific operating conditions, while the KTN9/UP suffix indicates a polyamide cage and enhanced precision tolerance—features that minimize vibration and extend service life in continuous-duty equipment such as steel mill rollers and mining conveyors. Whether operating in high-speed rotary applications or handling heavy shock loads, the NN 3017 KTN9/UP maintains dimensional stability under varying temperatures and load conditions.
Technical Features That Maximize Equipment Reliability
The NN 3017 KTN9/UP’s double row configuration provides 30% higher radial load capacity compared to single row designs, making it ideal for heavy machinery subjected to continuous stress. The polyamide cage ensures uniform roller spacing, reducing friction and heat generation during high-speed operation—critical for maintaining spindle accuracy in machine tools. With an inner diameter of 85 mm, this bearing fits standard industrial shafts, while its cylindrical structure allows for easy mounting and dismounting during maintenance. The UP precision class guarantees tight radial runout tolerances, essential for applications where rotational accuracy directly impacts product quality, such as metalworking and precision manufacturing.
Avoid Hidden Costs of Counterfeit Bearings
Choosing non-genuine bearings may seem cost-effective initially, but the long-term consequences often include early failure, increased energy consumption, and secondary equipment damage. Counterfeit cylindrical roller bearings typically lack proper heat treatment, leading to premature wear and potential catastrophic failure under load. In contrast, SKF’s ISO 9001-certified manufacturing process ensures each NN 3017 KTN9/UP bearing meets严格 material and performance standards, reducing total cost of ownership by minimizing replacement frequency and unplanned downtime. For critical applications like steel plant rolling mills or mining crushers, the reliability of genuine SKF components directly protects your production schedule and worker safety.
