For all your bearings and taper roller bearings,
we can supply Nilos Rings in every size and type:
NILOS-Rings are a by-word throughout the entire world for the simple and space- saving sealing of roller bearings. The correct type of NILOS-Ring at the right place reduces the costs of the design as well as improving it.
The standard types of ring are produced from gal- vanised special strip steel. On request NILOS-Rings can also be produced from stainless steel or brass.
There is no such thing as a universal seal for all opera- ting conditions and bearing r.p.m.. Our well-proven sealing elements represent a comprehensive range of various types of NILOS-Rings.
These types of NILOS-Rings are covered in detail on the following pages, with information on what they can be used for and how they can be installed.
For all other sealing problems we produce sealing springs and cover plates in the DIFKU and DISKU types of NILOS-Rings which have already proven their worth in numerous applications.
Two basic shapes of seals AV, JV
These two types of NILOS-Rings cover the majority of configura- tions used. The standard types of NILOS-Rings can be used for peripheral rotating speeds of up to 6 m/s; higher speeds must quoted without fail when ordering.
For Z and RS bearings ZAV, ZJV
The sealing of bearings that have already been provided with shields or seals is done by NILOS-Rings of other dimensions so that the seal clamped into the bearing is fully encapsulated by the NILOS-Ring. NILOS-Rings are required in particular in such cases if dirt can penetrate up to the bearing or if condensation is formed.
For taper roller bearings AV, JV, AK
The two forms of NILOS-Ring, the AV and the JV, are produced for the bearing sides shown in the illustration. The dimensions of the sealing edge are significantly different from those for other forms due to the difference in width between the inner and outer bearing rings. They are dimensioned such that they can be guaranteed to always be in place on the roller bearing ring and thus ensure that proper sealing is achieved in all cases.
Sealing package comprising of steel disks are ready for installation and capable of handling thrust loads. The sealing works on a non- contact basis and can follow axial movements of the roller bearing rings to 0.3 mm with- out any jamming of the disc
The type LST-L ring is a further development of the type LSTO NILOS ring. By means of an additional Viton gasket, a considerable sealing effect is achieved when in contact with liquids.
The NILOS ring is the ideal solution for your sealing problem:
Tight for more than 60 years. In almost all areas:
There are several ways to seal a hydraulic cylinder, and using different types of seals can help prevent leaks and ensure proper operation of the cylinder. Here are a few ideas:
It's important to use the appropriate seals and other components for your specific hydraulic cylinder to ensure proper sealing and operation.
There are several ways to seal a hydraulic cylinder:
1. Piston seal: This is a sealing element that prevents fluid from leaking past the piston as it moves within the cylinder. Some synonyms for this component include: O-ring, packing, seal ring.
2. Rod seal: This is a sealing element that prevents fluid from leaking past the rod as it extends and retracts within the cylinder. Some synonyms for this component include: lip seal, scraper seal, dynamic seal.
3. Wiper: This is a component that removes contaminants and debris from the rod as it extends and retracts within the cylinder. Some synonyms for this component include: dust seal, dirt scraper, rod protector.
4. Guide band: This is a component that helps guide the rod as it extends and retracts within the cylinder. Some synonyms for this component include: guide ring, guide bushing, rod guide.
It's important to properly seal a hydraulic cylinder to ensure the system operates efficiently and effectively. Using high-quality sealing elements and regularly maintaining and replacing them as needed can help prolong the life of the cylinder and prevent costly repairs.
Piston seal: O-ring, gasket, packing, sealing ring, sealing element Rod seal: Lip seal, radial seal, dynamic seal, reciprocating seal, shaft seal Wiper: Scraper, cleaner, wipeless seal, dust seal, dirt seal Guide band: Guide ring, guide bushing, guide element, guiding element, guiding ring
A slydring is a type of hydraulic seal specifically designed for use in high-pressure, high-temperature environments. It is made of a special material called PTFE (polytetrafluoroethylene) that is resistant to wear and abrasion, and it is used to seal the gap between a piston rod and a cylinder bore in a hydraulic cylinder.
A glydring is a type of hydraulic seal that is similar to a slydring in that it is made of PTFE and is used in high-pressure, high-temperature environments. However, a glydring is designed to seal the gap between two moving parts in a hydraulic system, such as between a pump and a motor or between two rotating shafts.
A slydring is a type of seal that is used to seal the gap between a moving and a stationary component in a hydraulic system. It is typically made of a flexible material such as rubber or polyurethane and is designed to provide a low-friction seal that prevents leakage of fluid or contaminants from the system.
A glydring is a type of seal that is similar to a slydring but is made of a material that is resistant to high temperatures and is specifically designed for use in high-temperature applications. It is often used to seal gaps between moving and stationary components in high-temperature hydraulic systems or in other high-temperature environments.
A single acting piston seal is a type of seal that is used in a hydraulic cylinder that only applies pressure in one direction. This type of seal is typically used in applications where the cylinder only needs to extend or retract, such as in a dump truck hoist or a car jack.
A double acting piston seal, on the other hand, is a type of seal that is used in a hydraulic cylinder that applies pressure in both directions. This type of seal is typically used in applications where the cylinder needs to extend and retract, such as in a hydraulic press or a hydraulic lift.
An example of a single acting piston seal might be a rubber o-ring that is used to seal the gap between the cylinder and the piston in a single acting hydraulic cylinder. An example of a double acting piston seal might be a pair of u-shaped seals that are used to seal the gap between the cylinder and the piston in a double acting hydraulic cylinder.
A single acting piston seal is a type of seal that is used to seal the gap between a moving and a stationary component in a hydraulic system where fluid pressure is applied to only one side of the piston. This type of seal is typically used in applications where the piston only needs to move in one direction. An example of a single acting piston seal is a seal used in a hydraulic jack or a hydraulic press.
A double acting piston seal is a type of seal that is used to seal the gap between a moving and a stationary component in a hydraulic system where fluid pressure is applied to both sides of the piston. This type of seal is typically used in applications where the piston needs to move in both directions. An example of a double acting piston seal is a seal used in a hydraulic cylinder on a bulldozer or a hydraulic cylinder on a forklift.
