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 relationship between capacity and size is critical.

The SF series designation is interpreted with a number that indicates the shaft diameter, followed by the letters SF and a second number that defines the width. 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 you to quickly identify the shaft size and the bearing width.

Its ability to withstand high radial loads in tight spaces makes it ideal for applications where ball bearings would not be sufficient or would require a larger size.
