Cylindrical Roller Bearings FAG NJ308 -E-XL-TVP2-C3
The FAG NJ308 -E-XL-TVP2-C3 single-row cylindrical roller bearing, with dimensions of 40x90x23 mm, offers high radial load capacity and single-sided axial guidance.
The FAG NJ308 -E-XL-TVP2-C3 cylindrical roller bearing, as a radial roller bearing, can withstand high forces. With a bore of 40 mm, an outside diameter of 90 mm and a width of 23 mm, this rolling bearing complies with tolerance class P0/PN (ABEC 1). The open design without seals allows for flexible lubrication within the housing. Thanks to its split construction, the inner ring can be withdrawn from one side, which facilitates installation.
What is the NJ308 -E-XL-TVP2-C3 cylindrical roller bearing suitable for?
This single-row bearing functions as a support bearing. In addition to significant radial loads, it also accommodates axial forces from one direction, whilst allowing axial displacement in the opposite direction. Designers make specific use of this property to compensate for thermal length changes in shafts. Typical applications include bearing locations in mechanical and plant engineering where high radial forces act within a confined installation space and axial forces must be absorbed on one side only.
What is the function of the polyamide cage and the C3 clearance?
The integrated polyamide cage (TVP2) guides the rollers quietly and is characterised by its low weight. The C3 designation indicates an increased radial bearing clearance compared with the standard version. This radial clearance compensates for fit allowances and temperature differences between the inner and outer rings during operation, without the bearing becoming stressed. The component is suitable for a temperature range of -30 to +120 degrees.
What are the main dimensions of the NJ308 -E-XL-TVP2-C3 bearing?
With a bore of 40 mm, an outer diameter of 90 mm and a width of 23 mm, the bearing complies with standard installation dimensions. These dimensions allow for direct integration into suitable housing bores and onto corresponding shaft seats.
What characterises the NJ design in cylindrical roller bearings?
The NJ design is characterised by two solid flanges on the outer ring and one solid flange on the inner ring. This enables the bearing to act as a support bearing for axial guidance in one direction. The inner ring can be pulled off to one side, which facilitates installation and maintenance.
What does the designation ‘C3’ mean in relation to this cylindrical roller bearing?
The designation C3 indicates a slightly increased radial bearing clearance. This increased clearance between the cylindrical rollers and the raceways helps to prevent the bearing from seizing up in the event of tight shaft fits or operational heating of the inner ring.
What are the properties of the TVP2 polyamide cage?
Made from polyamide, the TVP2 version guides the rolling elements with low noise levels and reduces the weight of the roller set. The temperature range specified for this cage variant is from -30 to +120 degrees.
How is the NJ308 open cylindrical roller bearing lubricated?
As the bearing is manufactured without integrated sealing washers, grease or lubricating oil is supplied via the housing design. The outer ring has no groove and no lubrication bore, which is why the lubricant must be applied directly to the roller set from the end face.
In which tolerance class is the bearing manufactured?
Manufactured to tolerance class P0/PN (equivalent to ABEC 1), the component meets the standard dimensional and concentricity tolerances required for standard applications in mechanical engineering.
