Cylindrical Roller Bearings FAG NJ2210 -E-XL-TVP2
The FAG NJ2210 -E-XL-TVP2 cylindrical roller bearing, with a 50 mm bore, offers high radial load-carrying capacity and serves as an axial support bearing.
The NJ2210 -E-XL-TVP2 cylindrical roller bearing is a single-row rolling bearing from FAG Wälzlager, designed to withstand high radial forces. The NJ design features two fixed flanges on the outer ring and one fixed flange on the inner ring. As a result, this support bearing can accommodate not only radial loads but also axial guidance forces from one direction. With key dimensions of 50 mm inner diameter, 90 mm outer diameter and 23 mm width, this design is suitable for heavily loaded shaft mountings.
What is the NJ2210 -E-XL-TVP2 cylindrical roller bearing suitable for as a support bearing?
This radial roller bearing is primarily used where heavy radial loads occur and the shaft needs to be guided in an axial direction. Typical applications include shaft bearings subjected to combined loads in general mechanical engineering. As the inner ring can be removed from one side, the bearing can be fitted separately. This facilitates installation in confined spaces and simplifies maintenance procedures on shafts and bearing locations.
What characteristics does the TVP2 polyamide cage offer during operation?
The suffix TVP2 denotes a polyamide cage that guides the cylindrical rollers. This material reduces the cage’s weight and ensures quiet, vibration-damped operation. The design is rated for a temperature range of -30 to +120 degrees. As this is an open bearing without an integrated seal and without a lubrication bore in the outer ring, users select the lubricant and external sealing to suit the operating environment.
What is the function of the NJ2210 -E-XL-TVP2 cylindrical roller bearing?
A single-row cylindrical roller bearing of the NJ type is primarily designed to withstand very high radial loads. Thanks to the two flanges on the outer ring and the single flange on the inner ring, it also functions as a support bearing. It allows axial displacement in one direction whilst withstanding axial loads in the opposite direction.
What are the dimensions of the NJ2210 bearing?
The bearing has a bore of 50 mm, an outer diameter of 90 mm and a width of 23 mm. The outer ring is manufactured without a lubrication groove or lubrication bore, which means that lubrication takes place via the end faces.
What does the suffix ‘TVP2’ mean in the context of FAG?
The abbreviation TVP2 refers to a polyamide cage. Compared with metal cages, polyamide is characterised by its lower weight and favourable running characteristics in the event of temporary insufficient lubrication. The material absorbs shocks within the rolling element assembly and helps to reduce noise levels.
What temperature range is this model suitable for?
The roller bearing is specified for an operating range between -30 and +120 degrees. This range is determined by the polyamide cage fitted, the material properties of which remain dimensionally stable within these limits. When selecting a lubricant, you should choose one that fully covers this temperature range.
What is the bearing clearance and tolerance class of the bearing?
The product is manufactured with standard radial bearing clearance, which is designed for standard fit conditions and moderate temperature differences between the shaft and the housing. The dimensional and running tolerances correspond to tolerance class P0 or ABEC 1. This defines the tolerances for standard use in mechanical engineering.
Why is the inner ring removable in this design?
The NJ design allows the inner ring to be removed from one side, as it has only one flange. This separable design simplifies assembly. You can mount the inner ring and outer ring, together with the roller set, separately onto the shaft and housing, and then align the assemblies axially.
