CONTACT-FREE RINGSLSTO
Characteristics of LSTO type NILOS Rings: 

  • Triple-Radial Labyrinth with a height of just 4mm;

  • Noiseless / frictionless operation;

  • Adaptable to any kind of bearing;

  • Can also be used with conic roll bearings adpated with distancing rings.

 
  
Please note that: 
The reference for the LSTO type NILOS Ring is given by thge internal and external diameters (in mm) followed by the LSTO suffix 
For example: the LSTO NILOS Ring for the 6204 bearing is: 20 x 47 LSTO

Advantages of LSTO Rings

aneis_lsto2

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

  • Noiseless and frictionless;
  • Long and narrow factory lubricated labyrinths;
  • Capable of axial and radial movement to compensate vibrations, slack and axis/bushing misalignment;
  • 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 stops and bearing replacements;
  • Increase the life span of bearings and lubricants.

 

Advantages of Nilos Rings over conventional seals:

  • Allow relubrications and can be reused;
  • Allow choice and use of lubricants for specific conditions;
  • 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.

Assembly instructions for LSTO Rings

 

LSTO types – Triple-Radial Labyrinth

 

Help Tool

As installation and adjustments of type LSTO NILOS Rings interfere in the internal diameter (axis) and the external diameter (bushing), installation can only be achieved with the help of a tool, as shown in the picture to the right.

Solid-Steel Rims

Type LSTO NILOS Rings have their internal and external diameter rims made entirely of steel, which gives them great resistance, allowing them to endure, in these aspects, the same strains suffered by the bearings.

imag8


Ideal Assembly Side

Type LSTO NILOS Rings DO NOT require a specific side for them to be mounted.

LSTO Rings

 
 

LSTO Rings are made of steel discs combined to create a triple radial micro-labyrinth, filled with lubricant. LSTO Rings are contact-free: their operation do not rely on friction of its parts on the bearing to provide efficient sealing. They are ideal for high contamination level environments and also applications that demand low noise and low friction levels.


Advantages of JV Rings and derivates

aneis_jv

 

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.

Assembly Behind the Bearing

Assemble the NILOS RING and the bearing.

imag2


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.

imag3


Concentricity

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

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

imag4


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.
