Cylindrical Roller Bearings FAG NU212 -E-XL-TVP2-C3
The FAG NU212 -E-XL-TVP2-C3 cylindrical roller bearing, with a 60 mm bore, offers high radial load-carrying capacity as a non-locating bearing with C3 clearance.
The NU212 -E-XL-TVP2-C3 cylindrical roller bearing is a single-row radial roller bearing designed for demanding industrial applications. With dimensions of 60 × 110 × 22 mm, the design can withstand high radial loads. As a non-locating bearing of the NU design, the bearing has two fixed flanges on the outer ring, whilst the inner ring is flangeless. This allows the inner ring to be removed from either side, which facilitates assembly and compensates for axial length changes of the shaft within the bearing.
What is the NU212 -E-XL-TVP2-C3 cylindrical roller bearing suitable for?
This radial roller bearing is primarily used as a non-locating bearing in bearing arrangements subject to significant radial loads. As the inner ring has no flanges, the component transmits purely radial forces. The design accommodates thermal linear expansion of shafts without constraint, preventing harmful axial stresses from developing in the bearing system. The integrated polyamide cage ensures quiet guidance of the cylindrical rollers.
What do the C3 clearance and TVP2 cage mean for this bearing?
The suffix TVP2 denotes a solid polyamide cage that combines low weight with elastic running characteristics. The permissible temperature range is from –30 to +120 degrees. The designation C3 indicates an increased radial bearing clearance compared with standard clearance. This reserve prevents the rolling elements from jamming if operational heating or tight fits reduce the radial bearing clearance during operation.
What are the dimensions of the NU212 -E-XL-TVP2-C3 cylindrical roller bearing?
The bearing has a bore diameter of 60 mm, an outer diameter of 110 mm and a width of 22 mm. These standardised key dimensions determine the required installation space on the shaft and within the bearing housing. Manufacturing is carried out to tolerance class P0/PN or ABEC 1.
What are the distinctive features of the NU design in the NU212 cylindrical roller bearing?
In the NU design, the outer ring guides the rollers between two fixed flanges, whilst the inner ring has no flanges on either side. This means that the inner ring can be completely removed. This allows the inner and outer rings to be fitted separately and permits axial movement of the shaft relative to the housing.
Why has bearing air class C3 been chosen?
Bearing clearance class C3 has greater radial clearance than the standard class. This is advantageous where temperature differences occur between the inner and outer rings, or where tight fits on the shaft and housing reduce the radial bearing clearance after press-fitting. This ensures that the bearing continues to run smoothly and is protected against seizing.
What are the features of the TVP2 cage?
The abbreviation TVP2 refers to a polyamide cage. This material is characterised by low inertia, good emergency running properties and quiet operation. The material limits the bearing’s continuous operating temperature range to between –30 and +120 degrees, which corresponds to standard industrial operating conditions.
How is the open bearing lubricated?
As the cylindrical roller bearing is supplied without integrated seals, lubrication must be provided via the surrounding structure. Depending on the operating conditions, it is suitable for either grease or oil lubrication. The outer ring has no groove and no lubrication bore, which is why lubricant must be applied directly to the sides of the rollers.
Can the NU212 cylindrical roller bearing accommodate axial forces?
No, as a pure radial bearing of the NU type, this component transmits only radial forces. Due to the flangeless inner ring, there is no axial contact surface for the cylindrical rollers. If axial forces occur in the system, these must be accommodated by a separate fixed bearing, such as a deep-groove ball bearing or a four-point contact bearing.
