The NSK SF series needle roller bearing is a radial needle roller bearing without an inner ring, designed for applications where radial space is limited and high load capacity is required. Its compact construction allows it to be mounted directly on a hardened and ground shaft, which simplifies the design and reduces the weight of the assembly. It is used in transmissions, pumps, compressors and industrial machinery in general, where the ratio between capacity and size is critical.
The SF series designation is interpreted with a number that indicates the shaft diameter or main dimension, followed by the letters SF and a second number that defines the width or capacity. For example, 5SF8 corresponds to a bearing for a 5 mm shaft and 8 mm width; 6SF10 for a 6 mm shaft and 10 mm width; 7SF12 for a 7 mm shaft and 12 mm width; 8SF14 for an 8 mm shaft and 14 mm width; 10SF16 for a 10 mm shaft and 16 mm width; 12SF20 for a 12 mm shaft and 20 mm width; 13SF22 for a 13 mm shaft and 22 mm width; 15SF24 for a 15 mm shaft and 24 mm width. This nomenclature allows quick identification of the shaft size and the bearing width.
In Argentine industry, SF series needle roller bearings are used in a wide variety of equipment: machine tool transmissions, water and oil pumps, air compressors, electric motors, gearboxes, and machinery for the food, textile and plastics industries. Their ability to withstand high radial loads in tight spaces makes them ideal for applications where ball bearings would not be sufficient or would require a larger size.
To correctly select an SF series needle roller bearing, it is essential to verify that the shaft meets the appropriate hardness and roughness, since the raceway is formed directly on the shaft. A minimum hardness of 58 HRC and low surface roughness are recommended to ensure a long service life. In addition, it is important to consider sealing: if the environment contains dust or moisture, additional seals or bearings with integrated seals should be used. Proper lubrication, whether grease or oil, and precise alignment between the shaft and the housing are key factors for reliable operation.
Regarding equivalents and interchangeability, NSK SF series needle roller bearings can be replaced by products from other brands that follow the same dimensional nomenclature, such as SKF, FAG, NTN or INA, as long as the dimensions and tolerances are verified. It is common for different manufacturers to use similar designations for bearings with the same dimensions, but it is the user's responsibility to confirm compatibility. At MR Accesorios Industriales we can advise you to find the right equivalent based on the part number you provide.

Frequently Asked Questions
- What does the SF designation mean in NSK needle roller bearings?
- The SF series identifies needle roller bearings without an inner ring. The number before indicates the shaft diameter and the one after the width. For example, 8SF14 is for an 8 mm shaft and 14 mm width. This nomenclature makes selection by shaft size easier.
- What are the most common applications of SF series needle roller bearings?
- They are used in transmissions, pumps, compressors, electric motors, gearboxes and industrial machinery where radial space is limited and high loads are required. They are also used in equipment in the food, textile and plastics industries.
- How can I request a quote for an NSK SF series needle roller bearing?
- Send the complete part number on WhatsApp to MR Accesorios Industriales. We will quote you promptly and, if you need it, indicate the compatible alternative from another brand. We can also advise you on assembly and lubrication.
