Cylindrical Roller Bearings FAG NJ2309 -E-XL-TVP2-C3
The NJ2309 -E-XL-TVP2-C3 cylindrical roller bearing, measuring 45 × 100 × 36 mm, can accommodate high radial loads and provides single-sided axial guidance.
The single-row cylindrical roller bearing NJ2309 -E-XL-TVP2-C3 from FAG is designed for demanding industrial applications. With a bore of 45 mm, an outside diameter of 100 mm and a width of 36 mm, this roller bearing can withstand very high radial forces. Designed as a support bearing with a single-sided removable inner ring, the component guides a shaft in one axial direction whilst compensating for length changes in the opposite direction. The design complies with the standard tolerance class P0 (ABEC 1) and is suitable for operating temperatures ranging from -30 to +120 degrees Celsius.
What is the NJ2309 -E-XL-TVP2-C3 cylindrical roller bearing suitable for?
This cylindrical roller bearing is primarily used where heavy radial loads act on rotating shafts and axial guidance in one direction is required. Typical applications include bearing arrangements subject to combined loads in mechanical engineering. As the outer ring is designed without a groove or lubrication bore, the lubricant is supplied via the surrounding housing. The separately mountable inner ring simplifies installation in confined spaces, which can have a positive impact on assembly times during maintenance operations.
What are the distinctive features of the NJ design with a polyamide cage and C3 clearance?
The designation ‘NJ’ defines the bearing as a thrust bearing with two fixed flanges on the outer ring and one flange on the inner ring. This enables it to accommodate axial forces in one direction. The integrated polyamide cage ensures quiet running and reduces the weight of the rotating mass compared with solid metal cages. The increased radial clearance (C3) provides additional leeway in the event of heating during operation or where there are tight fits on the shaft. As an open bearing, this design requires external sealing of the bearing housing.
What are the distinctive features of the NJ design in the NJ2309 cylindrical roller bearing?
The NJ design features two fixed flanges on the outer ring and one fixed flange on the inner ring. This allows the bearing to function as a support bearing. In addition to high radial forces, it also accommodates axial forces acting in one direction. The inner ring can be withdrawn from one side, which facilitates the separate installation of the inner and outer rings in the machine.
What are the dimensions of the NJ2309 -E-XL-TVP2-C3 cylindrical roller bearing?
This bearing has an inner diameter of 45 mm, an outer diameter of 100 mm and a width of 36 mm. Its wide design provides large-area raceways and cylindrical rollers, which contribute to a high radial load-carrying capacity.
What does the suffix ‘TVP2’ mean in relation to this bearing?
The designation TVP2 indicates a polyamide cage. This material is characterised by its low weight and damping properties, which promote smooth, low-vibration operation. The polyamide cage limits the bearing’s continuous operating temperature range to between –30 and +120 degrees Celsius.
Why is the C3 clearance suitable for this cylindrical roller bearing?
The designation C3 indicates a larger radial clearance than in the standard version. It compensates for thermal expansion when temperature differences arise between the inner and outer rings during operation. Furthermore, the increased radial clearance helps to prevent the bearing from becoming stressed if the inner or outer ring is fitted with a tighter fit.
How is the NJ2309 open cylindrical roller bearing lubricated and sealed?
As this is an open bearing without integrated sealing washers, the bearing housing must be sealed by the surrounding housing structure. The bearing has no lubrication bore in the outer ring. Grease or oil is therefore supplied directly from the side via the bearing chamber. A clean housing seal prevents the ingress of dirt particles.
Which tolerance class does the NJ2309 -E-XL-TVP2-C3 cylindrical roller bearing correspond to?
The bearing is manufactured to the standard tolerance P0, which corresponds to ABEC Class 1 in the US. This standard accuracy class meets the requirements of general mechanical and plant engineering. It ensures that defined dimensional accuracy is maintained for bore, outer and width dimensions in standard industrial housings.
