Cylindrical Roller Bearings FAG NUP312 -E-XL-TVP2
The FAG NUP312 -E-XL-TVP2 cylindrical roller bearing is used as a fixed bearing for shafts with a 60 mm bore to accommodate high radial loads.
The single-row cylindrical roller bearing NUP312 -E-XL-TVP2 from FAG withstands high radial forces whilst also serving to axially fix a shaft in both directions. With dimensions of a 60 mm bore, 130 mm outer diameter and 31 mm width, this open roller bearing is widely used in mechanical engineering. The polyamide cage contributes to the quiet running of the cylindrical rollers. Manufactured to tolerance class P0 (ABEC 1) and with standard radial clearance, this rolling bearing meets a wide range of industrial requirements.
What is the NUP312 -E-XL-TVP2 cylindrical roller bearing suitable for?
Design engineers primarily use this cylindrical roller bearing in industrial drives and gearbox applications. The NUP design demonstrates its advantages wherever high radial loads occur and the shaft needs to be axially guided on both sides. The outer ring has two fixed flanges, whilst the inner ring has one fixed flange and one loose flange disc. As a result, the component transmits not only the dominant radial forces but also axial guiding forces in both directions.
What advantages does the TVP2 polyamide cage offer in practice?
The designation TVP2 denotes a solid, window-type cage made of polyamide, which keeps the rollers spaced apart. Compared with metal cages, this material is characterised by its low weight and dampens vibrations during operation. When specifying the operating parameters, the permissible temperature range of -30 to +120 degrees must be taken into account to prevent premature ageing of the polyamide.
What are the distinctive features of the NUP design in the NUP312 -E-XL-TVP2 cylindrical roller bearing?
As a fixed bearing, this design features two fixed flanges on the outer ring and one fixed flange and one loose flange disc on the inner ring. This design guides the shaft in both axial directions and, in addition to its high radial load-carrying capacity, also accommodates limited axial guiding forces.
What are the dimensions of the NUP312 -E-XL-TVP2 cylindrical roller bearing?
With an internal diameter of 60 mm, an external diameter of 130 mm and a width of 31 mm, the bearing complies with standardised dimensions. It is a single-row cylindrical roller bearing without a groove or lubrication bore in the outer ring, manufactured to standard tolerance P0 or ABEC 1.
What does the suffix ‘TVP2’ mean in relation to this roller bearing?
The abbreviation TVP2 refers to a solid polyamide window cage. This type of cage is characterised by its low weight, elastic properties and good vibration damping. At the same time, it ensures low-friction guidance of the cylindrical roller elements during operation.
What is the operating temperature range for the bearing?
The permissible operating temperature range is between -30 and +120 degrees. This range is primarily limited by the material of the TVP2 polyamide cage. For correct operation, it is recommended to use a lubricant whose viscosity and thermal stability are suited to this operating range.
Why does the NUP312 -E-XL-TVP2 cylindrical roller bearing have an open design?
Without integrated sealing washers, the open design allows for flexible lubrication with grease or oil via the surrounding housing. From a design perspective, care must be taken to ensure the housing is externally sealed to prevent the ingress of dirt and lubricant loss during operation.
What is the clearance in the cylindrical roller bearing?
The component has the standard radial bearing clearance (normal clearance). The radial operating clearance is designed to ensure smooth, jam-free operation with precise shaft guidance when used with standard fits on the shaft and housing, and at normal operating temperatures.
