NILOS Rings

The History

The Ziller Holding Company was established in 1926 in Hilden Germany, near Dusseldorf by Dr. Hans Ziller. The holding group consists of Nilos Ring, Nilos Belting, Kroll & Ziller Gaskets and Coal Control.

Who NILOS- Rings is:

• comprised of 70 employees in Production, R & D and Distribution
• have their own development department, tool design and construction
• represented by over 40 distribution partners
• have over 3 million NILOS-Rings in stock
• over 5000 Nilos Ring tools from 9mm OD to 540mm OD
• ISO 9001:2000

Benefits of Using NILOS-Ring Products:

• optical quality control
• fabrication quality control
• state-of-the-art production
• has their own research and development department
• designs and manufactures their own tooling in-house

Types of NILOS-Rings:

• an “AV” ring seals the outer bearing. (see pic)
• a “JV” is a ring that seals the inner ball bearing. The sealing lip is smaller, therefore a higher speed is possible. Also, the sealing edge is not under pressure from the centrifugal force of the lubricant. (see pic)
• an “AK” consists of two spot welded rings where the inner edge seals at the outer bearing ring and the outer edge seals in the housing. (see pic)

A LSTO-Ring is a labyrinth seal which has:

• non contact
• has lubricant inside
• suitability for high velocity
• version LST-L Ring which is an enhanced version of the LSTO Ring with an added Viton gasket inside

Advantages of NILOS-Rings:

• don’t need much space
• due to the small overall height they can be mounted into existing designs
• the all metal construction makes them rigid and very rugged
• are resistant to a wide range of extreme temperatures from -40F to 752F
• re-greasing of the bearing is NOT required if NILOS-Rings are used on both sides

Standard Materials

• galvanized steel – covered with 3 micron zinc
• brass – for applications close to the sea
• stainless steel – for food applications and chemical industry

Field applications for NILOS-Rings:

• Materials Handling
• Agricultural Machines
• Electro-tools and motors
• Gearboxes
• Automotive Engineering

Several examples of NILOS-Ring applications:

• Type AV in the idler of an escalator (see pic)
• Types AV/JV and LSTO in the bearing of an idler (see pic)
• Types LSTO and JV in the bearings of a disc hub (see pic)
• Types AV and JV sealing the bearings of an angle grinder (see pic)
• Type LSTO in the bearing of a drum motor (see pic)
• Types AV and JV in the bearings of a gear unit (see pic)
• Type LSTO in a compressor (see pic)
• Types AK and JV in a fork lift truck’s steering axle (see pic)
• Type AV in a shock absorbing leg bearing (see pic)
• Type DISKU in the bearing of a Vibrato motor (see pic)
