Cylindrical Roller Bearings FAG NJ2306 -E-XL-TVP2
The FAG NJ2306 -E-XL-TVP2 cylindrical roller bearing, with dimensions of 30x72x27 mm and a polyamide cage, provides a robust guide for unilateral axial and high radial forces.
The NJ2306 -E-XL-TVP2 cylindrical roller bearing is a single-row rolling bearing with cylindrical rollers, specifically designed to accommodate heavy radial loads. As an open support bearing, this FAG design also guides the shaft in the axial direction, whilst the inner ring remains removable from one side. With a bore of 30 mm, an outside diameter of 72 mm and a width of 27 mm, the component is suitable for demanding applications in mechanical engineering.
What is the NJ2306 -E-XL-TVP2 cylindrical roller bearing suitable for in operation?
Design engineers use this support bearing when high radial forces act on the shaft and axial displacement in one direction needs to be limited. Typical applications are found in general mechanical engineering for shaft mountings with single-sided guidance. Thanks to the line contact between the rollers and raceways, the bearing can withstand even heavy loads. The polyamide cage contributes to smooth running at operating temperatures between –30 and +120 degrees Celsius.
What are the key considerations regarding the design and the polyamide cage?
In the NJ design, the outer ring has two solid flanges, whilst the inner ring is manufactured with only one flange. This allows the shaft to be supported axially on one side; however, it requires the correct installation direction to be observed in the design. The suffix TVP2 indicates a lightweight polyamide cage that dampens vibrations. As this is an open design without seals, the lubricant must be supplied via the surrounding structure.
What are the dimensions of the NJ2306 -E-XL-TVP2 cylindrical roller bearing?
The bearing has an internal diameter of 30 mm, an external diameter of 72 mm and a width of 27 mm. These standardised dimensions allow for a precise replacement in existing assemblies or housings, provided that the mounting dimensions of the shaft and the bearing seat are compatible.
What does the ‘NJ’ design designation mean for this roller bearing?
The designation NJ refers to a support bearing whose outer ring has two solid flanges, whilst the inner ring has a single flange. This enables the bearing to accommodate not only heavy radial forces but also axial guidance forces from one direction. The inner ring can be removed axially in the opposite direction for assembly purposes.
What are the key features of the TVP2 polyamide cage?
The abbreviation TVP2 refers to a polyamide cage. This material reduces the cage’s own weight and minimises friction on the rollers, which promotes smooth running. The material is designed for a bearing operating temperature range of -30 to +120 degrees Celsius.
Why is this cylindrical roller bearing supplied as an open bearing?
Open roller bearings are supplied by the manufacturer without either cover plates or sealing plates and are suitable for installation in enclosed housings with external sealing. Lubricants can reach the raceways unhindered, whilst the housing seal of the surrounding structure prevents the ingress of dirt and moisture.
What is the bearing clearance and tolerance class of the bearing?
This cylindrical roller bearing is manufactured with a standard radial clearance and complies with the standard specifications for general mechanical engineering. The dimensional and concentricity tolerances comply with tolerance class P0/PN or ABEC 1. It is therefore suitable for shaft fits that do not require increased bearing clearance.
Does the outer ring have a lubrication bore?
No, the outer ring of this design has no circumferential groove and no lubrication bore. The lubricant must therefore be introduced axially into the interior of the bearing from the end faces, which should be taken into account when designing the lubrication channels in the housing.
