SKF cylindrical roller thrust bearings with the TN suffix are built for axial loads acting in one direction. The cylindrical rolling elements and polyamide cage support high axial rigidity, which suits industrial machinery running under heavy loads at moderate speeds, including presses, cranes and transmission equipment. MR Industrial Accessories supplies this line within its SKF bearing range.

Reading the code helps you match a replacement quickly. The numeric prefix identifies a single-direction cylindrical roller thrust bearing with a specific section height, and the TN suffix tells you the cage is polyamide, a material chosen to lower weight and improve sliding. Take 81102 TN: bore 15 mm. Then 81103 TN: bore 17 mm. And 81104 TN: bore 20 mm. With that structure you can pick out the key dimensions and cage type at a glance.

These bearings fit assemblies where axial forces dominate and load capacity matters. Typical examples include hydraulic presses, cranes, mills, mining equipment, construction machinery, transmission gearboxes, machine tool spindles and lifting systems. Because they handle unidirectional loads, they also work in setups such as lathe faceplates or rotary tables where the force arrives from one side.

Selection starts with the axial load, the rotational speed and the operating environment. Mounting must keep the shaft and housing precisely aligned, since these bearings do not tolerate misalignment well. Lubrication also plays a central role: use quality grease or oil and keep a proper lubricant film. The polyamide cage resists temperature and chemicals reasonably well, but extreme temperatures are not advisable. Check axial clearance and sealing to suit the surrounding conditions.

For interchangeability, SKF cylindrical roller thrust bearings with the TN suffix can be replaced by other manufacturers' products that share the same dimensional designation. Tolerances and load capacity may differ between brands, so verify them. Even though the TN suffix is standard, cage design or heat treatment can vary slightly from one maker to another. Always review the original manufacturer's technical data before confirming compatibility, and MR Industrial Accessories can help you evaluate a suitable alternative.
