Cylindrical Roller Bearings FAG NU2217 -E-XL-TVP2-C3
The FAG NU2217 -E-XL-TVP2-C3 cylindrical roller bearing (85x150x36 mm) is a single-row non-locating bearing designed to accommodate high radial loads at varying operating temperatures.
The NU2217 -E-XL-TVP2-C3 cylindrical roller bearing is an open, single-row radial roller bearing from FAG for industrial applications. With a bore of 85 mm, an outer diameter of 150 mm and a width of 36 mm, this design serves as a classic idler bearing. The NU design allows the inner ring to be removed from both sides, which facilitates separate installation. The design accommodates purely radial forces without any axial load components.
What is the NU2217 -E-XL-TVP2-C3 cylindrical roller bearing suitable for?
This cylindrical roller bearing is suitable for bearing arrangements where high radial forces are present and temperature-induced changes in shaft length need to be compensated for. As a non-locating bearing, the NU design allows for axial displacement between the shaft and housing directly within the bearing. As this is an open bearing without an integrated seal, the component is incorporated into a lubricated assembly with external sealing.
What do the designations TVP2 and C3 mean in the NU2217?
The designation TVP2 stands for a polyamide cage which guides the cylindrical rollers and reduces the mass compared with metal cages. The suffix C3 indicates a slightly increased radial bearing clearance compared with the standard version. This increased operating clearance compensates for thermal expansion when temperature differences arise between the inner and outer rings during operation. The permissible temperature range is from -30 to +120 degrees.
What are the dimensions of the NU2217 -E-XL-TVP2-C3 cylindrical roller bearing?
The bearing has an inner diameter of 85 mm, an outer diameter of 150 mm and a width across flats of 36 mm. It is manufactured to tolerance class P0/PN or ABEC 1 and functions as a single-row radial ball bearing.
What is the function of the NU design as a non-locating bearing?
The NU design features two fixed flanges on the outer ring and a flangeless inner ring. This allows the inner ring to be removed from either side and moved axially relative to the outer ring. The bearing compensates for changes in the shaft’s length without any binding and accommodates radial forces only.
What does the bearing clearance specification ‘C3’ mean for this bearing?
The designation C3 indicates a slightly increased radial clearance compared with the standard version. The additional radial clearance prevents the rollers from jamming when tight fits or temperature differences between the outer and inner rings cause the bearing to contract.
What are the special features of the TVP2 polyamide cage?
The suffix TVP2 denotes a solid polyamide cage. This material supports the rolling elements with a lower mass compared to metal cages, whilst operating at temperatures of up to +120 degrees.
How is the open bearing lubricated and sealed?
The cylindrical roller bearing is supplied ex-works without sealing washers or a lubrication channel in the outer ring. The lubricant, either oil or grease, is supplied via the machine housing. An external seal in the housing design protects the rolling element system from dirt and lubricant loss.
In what temperature range can the bearing be used?
The permissible temperature range is between -30 and +120 degrees. This thermal limit is primarily determined by the dimensionally stable polyamide cage, which is designed for operation within this range.
