NTN-SNR Bearings for the Cement Industry

NTN-SNR offers a wide range of large-sized tapered roller bearings and self-aligning bearing units specially designed for use at all stages of cement production: in crushers, clinker furnaces, coolers and gearboxes.

For cement producers, the problem of maintaining equipment in operable condition is closely related to the profitability of the business. In crushers, screens, conveyor belts used in cement plants, bearings are subjected to a number of negative effects (heavy loads, vibration, pollution), and therefore can fail just after a few weeks of operation. Each time this leads to a production stop for several hours or even days to replace bearings, the weight of which can reach hundreds of kilograms. Often this leads to disruption of production plans and increases financial costs.

Japanese-French concern NTN-SNR produces a whole line of tapered roller bearings, which are adapted to work in the most difficult conditions of cement plants. For all stages of production, NTN-SNR offers a wide range of bearings specifically designed for crushers, clinker furnaces, coolers and gearboxes:

  - spherical roller bearings of the ULTAGE series;

  - self-aligning bearing units;

  - large-sized tapered roller bearings with an outer diameter of more than 800 mm;

  - tapered roller bearings made of cemented steel, resistant to abrasion.

In these categories of bearings, a number of innovations are implemented:

- increased strength due to the optimized design of the steel separator, which is especially useful in applications such as vertical crushers;

- increased bearing capacity provided by special surface treatment technologies for rings and rollers;

- increased working speeds.

The use of NTN-SNR bearings in cement production results in significant savings in total cost of ownership by reducing maintenance costs and increasing service life.

It should also be noted that many models of large-sized NTN-SNR roller bearings are used not only in the cement, but also in the mining industry and in quarry equipment.
