When a shaft pushes its load in a single direction, an INA cylindrical roller thrust bearing can carry that thrust with a compact, rigid design. The cylindrical rollers and polyamide cage handle heavy axial forces, making these bearings common in gearboxes, pumps, machine tools and transmission assemblies. MR Industrial Accessories supplies this INA line to maintenance and purchasing teams across the United States and Latin America, and can help you match the right part number to your application.

The series code tells you two things. The base number sets the size, while the -TV suffix signals a glass fiber reinforced polyamide cage. So 81102-TV, 81103-TV and 81104-TV are the same bearing type in different shaft sizes. Reading the code this way speeds up identification when you are checking a drawing or an old bearing.

These bearings are built for high axial loads at moderate speeds. You will find them in speed reducers, centrifugal pumps, machine tools, lifting equipment and clutch systems, as well as in presses and positioning devices that need a stiff, short axial support. Because they take thrust in one direction only, they suit shafts where the load always pushes the same way.

Selection comes down to three things: which way the axial load points, how large it is, and how the bearing will be lubricated. Oil or grease both work, but the lubricant film must stay intact to avoid early wear. The raceways also need to be aligned; misalignment shortens service life. Press the bearing in with the right tools and never strike the rollers directly. The TV cage handles moderate temperatures and resists fatigue well.

For replacements, INA cylindrical roller thrust bearings can be interchanged with other brands that use the same dimensional designation, such as SKF or FAG, as long as you verify tolerances and cage type. Check the critical dimensions and load conditions before you swap a component. MR Industrial Accessories can review interchangeability with you.
