Description
SKF K 12X15X13 TN is a radial needle roller cage reference, within Bearings. Request a quote for K 12X15X13 TN via WhatsApp or email with the quantity you need; we respond promptly with lead time and equivalents.
The SKF K TN series needle roller cage is a bearing component that retains and guides the needle rollers, without inner or outer rings. It is used to build needle roller bearings directly on the shaft and housing, achieving compact assemblies with high radial load capacity. It is a common solution in applications where radial space is limited and rigidity and precision are required.
The K series designation is read with three dimensions: bore diameter, outside diameter and width, separated by an X. For example, K 10X13X10 TN indicates 10 mm bore diameter, 13 mm outside diameter and 10 mm width. The TN suffix identifies an injected polyamide cage, suitable for moderate temperatures and with good sliding properties. Other examples such as K 3X5X7 TN or K 10X16X12 TN show the variety of sizes in this series.
These cages are used in machine tools, pumps, compressors, electric motors, transmissions and automation equipment. In Argentina, they are common in the maintenance of agricultural, textile, food and packaging machinery, where a low-profile needle roller bearing is required. They also appear in gearboxes, camshafts and linkages that need high load capacity in little space.
To select a K TN cage, verify that the shaft and housing have the hardness and roughness suitable to act as raceways. Lubrication must be abundant and clean; in oil-lubricated assemblies, ensure the flow reaches the needles. Alignment between shaft and housing is critical: any misalignment reduces service life. Radial clearance is controlled by the shaft and housing tolerances, not by the cage.
SKF K TN series needle roller cages are interchangeable with equivalent components from other brands that follow the same dimensional designation. When replacing, compare not only the dimensions but also the cage type and material. SKF is an official brand that MR carries, so you can ask about alternatives within the same series. Always verify the complete part number before ordering.
If you need to identify the correct cage for your equipment, send us the part number engraved on the part or the shaft and housing dimensions by WhatsApp. At MR Accesorios Industriales we help you find the right SKF component for your application.

Frequently Asked Questions
- What does the TN suffix mean in a K cage?
- The TN suffix indicates that the cage is made of injected polyamide. This material offers good wear resistance and a low coefficient of friction, although it has temperature limits. It is important to verify the operating temperature to ensure adequate performance.
- Can I mount a K cage directly on the shaft?
- Yes, as long as the shaft is ground, has suitable surface hardness and a fine roughness. The shaft acts as the inner raceway of the bearing. The same applies to the housing, which acts as the outer raceway. Without these conditions, service life is drastically reduced.
- How do I request an SKF K TN series needle roller cage from MR?
- Send the complete part number by WhatsApp, for example K 10X13X10 TN, or the bore, outside and width dimensions. You can also ask about other sizes in the series. We will reply shortly with the quote.
