The Tandem Design: A Low-Friction
Alternative to Tapered Roller Bearings

The tandem design of the INA ball roller bearing is a double-row bearing whose ball roller rows are in a tandem arrangement. The rolling elements can be guided using one or two cages.

Our two cage design enables us to set both raceways independently of each other to perfectly match your application. This ensures maximum load support with minimum size and lower friction.

Substituting the line contact with two point contacts lowers the friction by around 30 % in comparison with tapered roller bearings. This means that the energy consumption can be significantly reduced.
