CONTACT RINGS			Internal Seal
Common characteristics shared by ALL NILOS Rings of Internal Seal
INTERNAL seal on the side of the bearing that needs sealing.
Ring is centered on the BUSHING.
It is fixed with a holding ring (elastic or fixed) or leans on a washer / spacer that operates on the OUTER ring of the bearing
Specific Characteristics
JV	For all bearings.
ZJV	Single seal for bearings WITH original seal (RS - 2RS) or protection plate (Z - ZZ).

 

Os NILOS Rings are very efficient, blocking impurities from getting into the bearings and holding lubricants inside. Some other advantages are:

• Made entirely of flexible metal with increasing sealing effect (ISE);
• Unlimited peripheral speed;
• Do not require finishing of contact surface;
• High temperature resistant;
• Reduced height, allowing simpler and more compact bushings;
• Do not require adaptations or machining for use after project completion;
• High durability and resistance;
• Drastically reduce maintenance downtime and bearing replacements;
• Increase the life span of bearings and lubricants.

The advantages of Nilos Rings over conventional seals:

• Allow relubrications and can be reused;
• Allow choice and use of lubricants for specific conditions;
• Their elasticity allow periodic lubrication, with option for permanent lubrication without disassembly;
• With Nilos Rings in stock, you can always (and only) acquire open bearings, that is, without original seals;
• Guaranteed sealing for any type of bearing, English or Metric system.

 

 

Anéis Nilos tipo AV / JV

 

Sealing Chamber

Fill up the NILOS RING Sealing Chamber with the same lubricant used in the bearing.

---

Assembly Behind the Bearing

Assemble the NILOS RING and the bearing.

---

Assembly in Front of the Bearing

Assemble the NILOS RING with the help of a tube in cases where the RING is installed in front of the bearing.

---

Concentricity

The NILOS RING must be centered along with the bearing, being:

AV Ring – on the AXIS
JV Ring – on the BUSHING

---

Fixing the Ring

The NILOS RING must be fixed firmly against the bearing in order to guarantee the formation of a micro groove and to keep it from slipping, as shown in drawing 4, being:

AV Ring – fixed on the inner ring of the bearing.
JV Ring – fixed on the outer ring of the bearing.

---

Spring Effect

In the first hours of operation, the NILOS RING acts like a spring plate, exerting a certain pressure on the internal ring (JV) or external ring (AV) of the bearing.

The Nilos Ring is mounted on the bushing and seals the bearing on its inner ring, where it creates the micro-labyrinth.

(Another ring of the same type: ZJV).
