NILOS-Rings All-metal seals for ball and roller bearings NILOS-Rings for ball and straight roller bearings NILOS-Rings for tapered roller bearings NILOS-Rings provide practical protection for ball and roller bearings against contamination by dirt and debris, including tough abrasive particles that can cause equipment to malfunction and productivity to be lost. These all-metal seals are ideal for grease-lubricated anti-friction bearings in industrial environments that routinely generate excessive contaminants, such as those conditions encountered in the mining, paper, agriculture, construction, and automotive industries. Creating an effective space-saving seal for ball and roller bearings even in the harshest operating conditions, NILOS-Rings offer a simple and easily incorporated method to help improve bearing performance and extend service life. Manufactured for durability and with precision, standard NILOS-Rings are produced from galvanized steel. Stainless and brass rings can be special-ordered as applications require. The NILOS product line includes specialized ring types designed to seal ball bearings, straight (non-tapered) roller bearings, and tapered roller bearings. Users can further take advantage of NILOS steeldisk seals for bearings that will operate in extreme conditions and spacer rings to promote non-slip clamping. All these products are profiled in this catalog and custom sealing solutions can be developed, based on decades of experience from an industry pioneer and leader. The two standard styles of NILOS-Rings for ball bearings and straight (non-tapered) roller bearings are type AV (for sealing a bearing’s outer ring) and type JV (for sealing a bearing’s inner ring). Both types are available in a wide range of sizes to fit particular bearing arrangements and can be utilized for circumferential speeds up to 1100 surface feet per minute at the contact diameter. To accommodate bearings already equipped with integral shields or seals, two variations of the standard styles are offered to provide added protection: type ZAV (for sealing a bearing’s outer ring) and type ZJV (for sealing a bearing’s inner ring). Each type is illustrated below in mounted position with selection examples to guide in specification. NILOS-Rings for ball and straight roller bearings AV-An externally sealing NILOS-Ring for a single-row 6410 deepgroove ball bearing would be designated type 6410 AV. JV-An internally sealing NILOS-Ring for a single-row 6410 deepgroove ball bearing would be designated type 6410 JV. Tapered roller bearings present unique design challenges if effective sealing is to be achieved, due to their “offset” cone and cup. For these bearing types three distinct standard styles of NILOS-Rings will serve: type AV (for sealing a tapered roller bearing’s outer ring); type JV (for sealing a tapered roller bearing’s inner ring); and type AK (featuring a unique two-disk design to enable “double-sealing” of a tapered roller bearing’s outer ring). All are available in a wide range of sizes to fit particular tapered roller bearing arrangements. Each type is illustrated below in mounted position with selection examples to guide in specification. ZAV-An externally sealing NILOS-Ring for a single-row deep-groove ball bearing 6205 with integrated shields/ seals would be designated type 6205 ZAV. ZJV-An internally sealing NILOS-Ring for single-row deep-groove ball bearing 6205 with integrated shield/seals would be designated type 6205 ZJV. NILOS-Rings for tapered roller bearings AV-An externally sealing NILOS-Ring for a single-row 302 07 tapered roller bearing would be designated type 302 07 AV. JV-An internally sealing NILOS-Ring for a single-row 302 07 tapered roller bearing would be designated type 302 07 JV. AK-A double externally sealing NILOS-Ring for a single-row 313 11 tapered roller bearing would be designated type 313 11 AK. 2
