General comments about Nilos Rings

NILOS do BRASIL manufactures special seals for bearings that operate mainly in polluted and aggressive environments where common or generic seals fail.

Nilos Rings are widely used and recommended:

1 At high temperatures or in places where there is quick and / or abnormal wear of bearings. These are the preferred situations and where NILOS RINGS excel. Their main technical feature is that they NEVER lose their sealing effect, because the secret, now revealed, is that their function of sealing by contact makes a narrow groove passage (micro-maze) which remains throughout the bearing life.

2 On the other hand, if a machine is already worn-out, was poorly built or badly designed, the wear on the bearings is huge and, in these cases, besides the high wear on the bearings, tons of lubricants are wasted trying to solve the problem caused by excessive friction. But even in these cases the situation can be minimized using NILOS RINGS, which have sufficient elasticity (contact seals) or axial and radial clearances (labyrinth) that can compensate for equipment vibrations and oscillations, and allow continuous or periodic lubrication.

3 Common seals require a very polished seal surface, trimmed, heat-treated and even coated with hard chrome. However, NILOS RINGS seal directly on the sides of the bearing without any need for finishing, grinding, polishing and heat-treated rings because the bearings already have a suitable surface for the sealing effect.
