SKF N 1017 KTN9/SP is a reference of cylindrical roller bearing, within Bearings. Request a quote for N 1017 KTN9/SP via WhatsApp or email with the quantity you need; we respond promptly with the quote and equivalents.
SKF cylindrical roller bearings are high radial capacity components, designed to withstand heavy loads and considerable speeds. Their single row design with guided rollers allows precise operation in demanding applications. At MR Accesorios Industriales we supply this line for the Argentine market, with technical advice so you can choose the right model for your equipment. If you need a quote, send us the part number by WhatsApp.
The designation of this series combines letters and numbers that indicate key characteristics. The letter N indicates a single row cylindrical roller bearing with a flangeless inner ring. The three or four digit number identifies the size. The suffix KTN9 indicates a polyamide cage with roller guidance, and /SP indicates a special tolerance for applications requiring higher precision. For example, N 1017 KTN9/SP and N 1018 KTN9/SP share these characteristics.
These bearings are used in industries such as metallurgy, cement, paper and mining, where radial loads are high and speeds are moderate. They also appear in gearboxes, high-flow pumps, industrial fans and machine tools. In Argentina, they are commonly found in grinding equipment, presses and power transmission systems. Their ability to withstand radial loads makes them suitable for interference fit mounting on the shaft.
To select correctly, take into account the radial load, speed and environmental conditions. Sealing is essential if there is contamination; in those cases, it is recommended to choose variants with seals or shields. Lubrication must be adequate: grease or oil depending on speed and temperature. Alignment between shaft and housing prevents additional stresses. Internal clearance should be chosen according to the fit and expected thermal expansion. Mounting with a hydraulic press and suitable tools ensures damage-free installation.
As for equivalents, SKF bearings of this series can be interchanged with those of other brands that follow the same standardized designation, such as FAG, NSK or NTN, as long as dimensions and tolerances match. It is important to verify the cage and precision suffix, since not all variants are interchangeable. For critical applications, consult the technical specifications of each manufacturer. MR Accesorios Industriales supplies SKF as a brand, and can advise you on the best option.

Frequently Asked Questions
- What does the KTN9 suffix mean in an SKF bearing?
- The KTN9 suffix indicates that the bearing has a polyamide cage with roller guidance. This cage is lightweight and resistant, suitable for high speeds. It does not change the external dimensions, but it does influence dynamic behavior.
- How do I choose between an N and an NU bearing?
- The N series has a flangeless inner ring, while NU has flanges on the inner ring. The choice depends on whether the bearing must allow axial displacement. Consult the equipment manual or contact us for advice.
- What tolerance does the /SP designation have?
- The /SP suffix indicates a special tolerance, tighter than standard. It is used in applications requiring high rotational precision, such as machine tool spindles. Always verify the manufacturer's specifications to confirm the exact values.
