Cylindrical Roller Bearings FAG N307 -E-XL-TVP2
FAG single-row cylindrical roller bearing N307 -E-XL-TVP2, dimensions 35x80x21 mm, designed as a separable support bearing for high radial loads.
The FAG N307 -E-XL-TVP2 cylindrical roller bearing is a single-row radial roller bearing for demanding mechanical applications. Thanks to the modified line contact between the rollers and raceways, the design can accommodate high radial forces. With a bore of 35 mm, an outside diameter of 80 mm and a width of 21 mm, this open roller bearing is suitable for industrial shaft guides where axial length changes need to be compensated for with low friction.
What is the N307 -E-XL-TVP2 cylindrical roller bearing suitable for as a non-locating bearing?
In bearing arrangements, the N307 -E-XL-TVP2 cylindrical roller bearing serves as a conventional non-locating bearing. As the outer ring is flangeless and removable from both sides, the shaft can be moved axially in both directions relative to the housing. The design thus accommodates temperature-induced linear expansion of shafts within the bearing itself without any constraint.
This design is suitable for radial loads where axial displacement is required. The integrated polyamide cage guides the rolling elements quietly at operating temperatures ranging from –30 to +120 degrees Celsius.
What are the distinctive features of the N design and the TVP2 cage?
The N design is characterised by two solid flanges on the inner ring, whilst the outer ring remains flangeless. This separable design considerably facilitates installation and removal, as both rings can be fitted separately onto the shaft and housing.
The suffix TVP2 denotes a lightweight polyamide cage. This cage material dampens vibrations and promotes smooth, elastic running. Furthermore, the bearing complies with the standard tolerance P0/PN (ABEC 1) with standard radial clearance. As this is an open design without seals and without a groove or lubrication bore on the outer ring, a lubricant supply via the housing must be provided.
What are the dimensions of the N307 -E-XL-TVP2 cylindrical roller bearing?
The bearing has a bore of 35 mm, an outer diameter of 80 mm and a width of 21 mm. These standardised key dimensions determine its fit on the shaft and in the bearing housing. The single-row roller bearing has a standard radial clearance and features an outer ring without a lubrication groove or bore.
What is the function of the N design in this cylindrical roller bearing?
In the N design, the inner ring guides the cylindrical rollers between two fixed flanges, whilst the outer ring is manufactured without flanges. This allows the outer ring to move axially relative to the set of rollers. The bearing acts purely as a non-locating bearing, accommodating thermal length changes in the shaft without generating any axial forces.
What are the characteristics of the polyamide cage designated TVP2?
The TVP2 polyamide cage is characterised by its low weight and damping properties. It guides the rolling elements with minimal friction and ensures quiet operation of the bearing. Polyamide cages are suitable for dynamic operating conditions, provided that the bearing’s permissible temperature range is observed.
What is the operating temperature range for this bearing?
The permissible operating temperature range is between -30 and +120 degrees Celsius. Both the material of the bearing rings and the polyamide cage fitted are designed for this range. When selecting a lubricant, care must be taken to ensure that the lubricant used remains effective within these temperature limits.
What does tolerance class P0 or ABEC 1 mean?
Tolerance class P0 (corresponding to PN or ABEC 1) defines the standard dimensional and running tolerances for rolling bearings. Bearings in this accuracy class are suitable for general mechanical and plant engineering. They provide precise guidance of rotating components whilst meeting standard industrial requirements for concentricity.
How is lubrication carried out in this open-type bearing design?
As the N307 -E-XL-TVP2 cylindrical roller bearing is designed as an open bearing without integrated sealing washers, the lubricant enters directly into the interior of the rolling elements. Protection against dirt and moisture, as well as lubricant retention, must be provided by the surrounding housing structure, as the outer ring has no lubrication bore.
