For machine tool spindles and rotary tables where space is tight and loads come from two directions, the SKF ZARN TN series provides a combined solution. Each unit pairs an axial washer with needles and a radial ring that uses a polyamide cage, so it handles simultaneous axial and radial forces in a compact envelope.

The code breaks down into two parts. ZARN signals an axial-radial needle roller bearing with an axial washer and radial ring. The number that follows gives the bore and outer diameter in millimeters: ZARN 2052 TN runs 20 mm bore by 52 mm outer, ZARN 3570 TN 35 mm by 70 mm, ZARN 5090 TN 50 mm by 90 mm, ZARN 50110 TN 50 mm by 110 mm, and ZARN 65125 TN 65 mm by 125 mm. The TN suffix denotes a polyamide cage, chosen for low friction at higher speeds.

Milling, boring and grinding spindles rely on these bearings to maintain rigidity under combined forces. Rotary tables, drill heads, indexing units and measuring equipment also use them. They suit metalworking, automotive and machine tool operations that demand precise rotation and positioning.

Selection depends on the mix of axial and radial loads, the speed, and the lubrication method. Where contaminants are present, sealed variants or oil seals at the mounting point protect the bearing. Shaft and housing alignment must be accurate to prevent parasitic loads. Grease or oil lubrication is possible, guided by speed and operating temperature. Follow the manufacturer's axial clearance recommendation for smooth running.

Other makers offer combined needle roller bearings under their own codes, and no exact cross-reference exists. To replace a ZARN TN, confirm bore, outer diameter and height, plus load capacities. Interchangeability across brands requires checking tolerances and clearance. MR Industrial Accessories supplies SKF and can help you identify a suitable equivalent for your application.
