The SKF needle roller bearing of the ZARN TN series is a combined bearing that supports axial and radial loads simultaneously. It is used in applications where axial space is limited and high load capacity is required, such as machine tool spindles, rotary tables and positioning systems. Its design includes an axial washer with needles and a radial ring with a polyamide cage, which allows compact and precise mounting.

The ZARN TN series designation is interpreted as follows: the letters ZARN identify an axial-radial needle roller bearing with an axial washer and radial ring. The numbers that follow indicate key dimensions: for example, ZARN 2052 TN has a bore diameter of 20 mm and an outer diameter of 52 mm; ZARN 3570 TN, 35 mm bore and 70 mm outer; ZARN 5090 TN, 50 mm and 90 mm; ZARN 50110 TN, 50 mm and 110 mm; and ZARN 65125 TN, 65 mm and 125 mm. The TN suffix indicates a polyamide cage, suitable for high speeds and low friction.

These bearings are used in milling, boring and grinding machine spindles, where they must withstand combined forces with high rigidity. They are also found in rotary tables, drill heads, indexing devices and measuring equipment. In Argentina, they are common in the metalworking, automotive and machine tool industries, especially in production plants that require high precision and reliability in rotation and positioning movements.

To select the appropriate bearing, take into account the combination of axial and radial loads, the rotation speed and the lubrication conditions. Sealing is crucial: if there are contaminants, choose variants with seals or protect the mounting with oil seals. Alignment between the shaft and the housing must be precise to avoid parasitic loads. Lubrication can be grease or oil, depending on speed and working temperature. Respect the axial clearance recommended by the manufacturer to ensure smooth operation.

Regarding equivalences, other manufacturers offer combined needle roller bearings with their own designations, but there is no exact correspondence between codes. To replace a ZARN TN, verify the critical dimensions (bore, outer diameter and height) and load capacities. Interchangeability between brands requires confirming tolerances and clearance. MR Accesorios Industriales sells SKF and can advise you on selecting the appropriate equivalent bearing for your application.
