Cylindrical Roller Bearings FAG N204 -E-XL-TVP2
The FAG N204 -E-XL-TVP2 cylindrical roller bearing, acting as a floating bearing with dimensions of 20 × 47 × 14 mm, withstands high radial loads and compensates for changes in length.
The N204 -E-XL-TVP2 cylindrical roller bearing from FAG Rolling Bearings is a single-row radial roller bearing designed for demanding industrial applications. Thanks to the line contact between the rollers and the raceway, this bearing can withstand high radial forces. With a bore of 20 mm, an outer diameter of 47 mm and a width of 14 mm, this open bearing is suitable for designs with an external lubrication supply. This version offers standard radial clearance and operates within a temperature range of -30 to +120 degrees Celsius.
What functions does the N204 -E-XL-TVP2 cylindrical roller bearing fulfil as a support bearing?
This rolling bearing is used in bearing arrangements where high radial forces must be accommodated. Due to its N design, the outer ring has no flanges and can be removed from both sides. The bearing arrangement thus functions purely as a non-locating bearing. It compensates for axial displacement of the shaft relative to the housing without restriction, thereby accommodating thermally induced changes in length during operation.
What are the distinctive features of the polyamide cage and the N design?
The integrated polyamide cage guides the cylindrical rollers with low friction and contributes to quiet running. The low weight of the plastic reduces the dynamic centrifugal forces in the bearing. As the open bearing design has no sealing washers, the housing design requires external sealing as well as continuous oil or grease lubrication. The removable outer ring also allows for the separate assembly of both bearing rings.
What are the main dimensions of the N204 -E-XL-TVP2 cylindrical roller bearing?
This bearing is characterised by a bore diameter of 20 mm, an outer diameter of 47 mm and a width of 14 mm. These nominal dimensions correspond to the standardised dimensions for cylindrical roller bearings in this series. When designing the shaft and housing, ensure that the removable outer ring can be fitted and positioned axially without obstruction.
What does the ‘N’ design designation mean for this roller bearing?
In the N design, there are two fixed flanges on the inner ring, whilst the outer ring has no flanges. This allows the outer ring to be removed from both ends. The bearing transmits radial forces only and acts as a non-locating bearing, so that changes in the shaft’s length due to heating are compensated for without causing axial stress in the bearing.
What is the permissible temperature range for the cylindrical roller bearing?
The permissible operating range for this bearing design is from -30 to +120 degrees Celsius. The temperature limits are largely determined by the polyamide cage fitted and the lubricant selected. For applications close to the upper temperature limit, you should use a grease or lubricating oil with appropriate temperature stability for the bearing.
What is the bearing clearance and tolerance class of the bearing?
The bearing is manufactured with standard radial clearance and complies with tolerance class P0 or standard tolerance according to ABEC 1. This standard configuration meets common installation requirements in general mechanical engineering. Provided there are standard fit conditions on the shaft and housing, the required operating clearance is maintained during operation.
How is the N204 -E-XL-TVP2 open cylindrical roller bearing lubricated?
As the bearing is of an open design and has no integrated seals, lubrication is provided by the surrounding assembly. You can operate the rolling bearing with grease or lubricating oil. It is important to have an external housing seal to keep the lubricant within the bearing area and prevent the ingress of dirt particles.
Why is a polyamide cage used in this bearing?
The polyamide cage is characterised by good sliding properties and low density. It guides the rolling elements in a vibration-damping manner, which contributes to smooth running. At the same time, the reduced cage weight minimises inertial forces during acceleration manoeuvres compared with designs featuring solid metal cages.
