Cylindrical Roller Bearings FAG NUP312 -E-XL-TVP2-C3
FAG nup312-e-xl-tvp2-c3 cylindrical roller bearing with a cylindrical bore, polyamide cage and C3 radial clearance for precise shaft guidance, with an outer diameter of 130 mm and a width of 31 mm.
The FAG nup312-e-xl-tvp2-c3 cylindrical roller bearing is an open roller bearing designed for demanding industrial applications involving high radial loads. The cylindrical bore allows the component to be mounted directly onto the cylindrical shaft. As there are no integrated seals, lubrication is supplied via the housing, which also protects the bearing from dirt and moisture. The design combines a high radial load-carrying capacity with precise axial guidance of the shaft.
What is the nup312-e-xl-tvp2-c3 cylindrical roller bearing suitable for?
This roller bearing is primarily designed to accommodate high radial forces in machinery and gearboxes. The NUP design functions as a fixed bearing and locks rotating shafts in both axial directions. Relevant areas of application arise where bilateral axial guidance of the shaft is required whilst simultaneously withstanding high radial loads. The permissible temperature range extends from -30 to +120 °C.
What are the advantages of a polyamide cage and C3 clearance?
The integrated polyamide cage ensures precise guidance of the cylindrical rollers and is characterised by its low weight and vibration-damping properties. The slightly increased C3 radial clearance compensates for temperature differences caused by operation and fixed fit allowances between the inner and outer rings. This reduces the risk of stress build-up during operation, contributing to smooth running and stable operating conditions.
What makes the nup312-e-xl-tvp2-c3 cylindrical roller bearing stand out?
With an outer diameter of 130 mm and a width of 31 mm, this FAG design features a cylindrical bore for direct shaft mounting. Fixed flanges on the outer ring, as well as a fixed flange and a loose flange disc on the inner ring, enable axial guidance of the shaft in both directions whilst maintaining a high radial load capacity.
What is the purpose of bearing clearance class C3 for this bearing?
The designation C3 indicates a slightly increased radial bearing clearance compared with the standard version. This additional clearance reduces the risk of the bearing becoming stressed when it heats up during operation or as a result of tight fits. It therefore supports the free rolling motion of the rolling elements under thermal and mechanical loads.
What are the properties of the polyamide cage used in the assembly?
Made from polyamide, the cage keeps the rolling elements at a uniform distance apart and reduces the mass inertia within the bearing. The material dampens vibrations and is characterised by favourable sliding properties when used in conjunction with the lubricant, which keeps friction to a minimum during operation.
Within what temperature range may the bearing be operated?
The bearing is approved for a temperature range of -30 to +120 °C. This range is primarily limited by the polyamide cage and the dimensional stability of the components. When designing the bearing assembly, the selected lubricant must also be suitable for these thermal conditions.
How is the open bearing lubricated and sealed?
As the bearing is designed without sealing washers, grease or oil is supplied via the surrounding structure. External sealing elements, such as radial shaft seals or gap seals in the housing, protect the raceways from contamination and prevent the lubricant from leaking out.
