INAPPROPRIATE LUBRICATION (55%) Inappropriate or incorrect lubrication significantly reduces the service life of the bearing. It is often neglected because of bearing accessibility problems and a lack of knowledge about lubricants on the side of the user. The choice of lubricant, the method, the quantity to apply to the bearing (neither too much nor too little) and the monitoring frequency must be properly studied. NTN-SNR offers you a special service and markets a complete range of greases covering all applications, as well as an automatic greasing system. The mounting of a bearing on a...

MOUNTING & REMOVAL GOOD PRACTICES FOR COLD MOUNTING Cold mounting is the simplest method and is suitable for small and medium-sized bearings, completed with the normal adjustments. OUR RECOMMENDATIONS: The most frequently observed problems: • Over- or under-tightening when adjusting. • xcessive impacts during mounting or forces causing rings and seals E to break, or races to become indented. • he accidental introduction of particles or liquids present in the T mounting environment. Analysis of rotation (% Incidence) Fixed housing and load (95%) Fixed load with respect to the outer ring...

COLD MOUNTING TOOL KIT CASE The NTN-SNR tool kit enables the quick, accurate and safe mounting of bearings. APPLICATIONS The use of a suitable socket, associated with the mounting sleeve, enables to install the bearing to the desired adjustment. The simultaneous support of the outer and inner rings prevents the risk of deterioration of the races and rotating assemblies. The kit can also be used for assembling other components such as sealing rings, sprockets and pulleys. ADVANTAGES Of light and strong construction for workshop use, this toolbox contains: 33 impact rings: • Very robust for a...

MOUNTING PASTE – ANTI-FRETTING AGENT The NTN-SNR mounting paste is specially designed to prevent contact rust, wear and fretting corrosion between 2 metal surfaces. It is an innovative heavy metal free paste, which is safe for the environment. APPLICATIONS • ontact corrosion, also known as fretting corrosion, appears in assemblies subjected to vibration or very slight slippage or C oscillation. It can lead to the serious deterioration of bearings and other machine components and thus make dismounting very difficult. ADVANTAGES • Allows slippage for assemblies with play (wheel bearings,...

MOUNTING & REMOVAL GOOD PRACTICES FOR HOT MOUNTING Hot mounting makes it possible, by raising the temperature of a rotating part, to expand the inner ring of a bearing or bore diameter of a sprocket so that it can be fitted over the shaft with ease. • n the event of a tightly fitting outer ring, prior to the insertion of the bearing, I the housing may be made to expand through heating. When a high-intensity, low voltage AC current passes through it, the part heats up quickly; while non-metallic parts and the device itself remain cool. • Conversely, a shaft can also be cooled using liquefied...

SINGLE-POINT HEATING MANAGEMENT From simple to extremely sensitive part, from the bearing to the sprocket, the NTN-SNR range offers the most suitable solution with real-time heating analysis and control. Depending on the type of part to be heated, 4 heating modes are available: • A Temperature mode using a sensor for non-sensitive parts. • A Time mode that enables to adjust the heating time only. • A Ramp mode for linear and controlled temperature rise dedicated to sprockets and other parts sensitive to temperature gradients. • A Temperature mode with 2 sensors to control the temperature...
