NTN-SNR ROX Spherical Roller Bearings

NTN-SNR ROX bearings are double-row spherical roller bearings designed to help protect against dust and retain grease in demanding industrial environments. Their distinguishing feature is a pair of patented metal deflectors integrated with the cage. These shields provide an additional barrier against solid contamination while preserving the dimensions of corresponding standard open bearings.

ROX is particularly relevant to conveyor head and tail pulley shafts in mines and quarries. Other applications include bucket elevators and industrial fans and blowers. It is also used in demanding sectors such as cement, metals, paper and forestry, where contamination can make maintenance more frequent.


How ROX Bearings Help Protect Dusty Conveyors?
Conveyor pulley bearings can be exposed to fine mineral dust, debris and moisture around the housing. When contaminants reach the rolling surfaces, they can cause damage and shorten bearing life.

ROX places metallic deflectors on both sides of the bearing to restrict the entry of solid particles and improve grease retention. The deflectors do not contact the outer ring, avoiding the rubbing friction associated with that contact. The nitrided steel cage and shields also improve resistance to impact and harsh operating conditions.

This design adds protection within the bearing assembly. The housing seals, lubrication and mounting arrangement still need to suit the application.

NTN Europe reports more than twice the bearing life and over 50% lower lubrication requirements for ROX compared with standard open solutions in its published product material. These figures describe manufacturer-reported results; the improvement in a particular machine depends on its operating conditions and maintenance practices.
