Cylindrical Roller Bearings FAG NJ2313 -E-XL-TVP2
The FAG NJ2313 -E-XL-TVP2 single-row cylindrical roller bearing, with dimensions of 65 × 140 × 48 mm, can accommodate high radial loads as well as unilateral axial forces.
The NJ2313 -E-XL-TVP2 cylindrical roller bearing is a single-row radial roller bearing from FAG Wälzlager with a 65 mm bore, 140 mm outer diameter and 48 mm width. Due to the line contact of the cylindrical rollers, this design can withstand considerable radial forces. Designed as an open bearing, the component can be flexibly integrated into existing lubrication circuits. For design and maintenance, the standard tolerance P0/PN ensures a precise fit when integrated into machine components.
What is the NJ2313 -E-XL-TVP2 cylindrical roller bearing suitable for in industrial applications?
This cylindrical roller bearing is primarily designed to support high radial loads on rotating shafts. Owing to its design as a support bearing, the component guides the shaft in one axial direction, whilst allowing axial displacement in the opposite direction. The inner ring is removable from one side, which facilitates the separate assembly of the inner and outer rings. This feature supports an efficient approach to the installation and maintenance of shaft bearings.
What are the advantages of the version with a TVP2 polyamide cage?
The suffix TVP2 denotes a polyamide cage. This material reduces the weight of the rolling element set and ensures particularly quiet and low-friction start-up. When selecting a bearing, you should take into account the permissible temperature range of -30 to +120 degrees, which is determined by the cage material. As the outer ring is designed without a groove or lubrication bore, the lubricant is supplied from the end face by design.
What are the main dimensions of the NJ2313 -E-XL-TVP2 cylindrical roller bearing?
With an internal diameter of 65 mm, an external diameter of 140 mm and a width of 48 mm, this roller bearing complies with the metric standard series for size 2313. Thanks to its single-row design, the component is suitable for compact installations subject to high radial loads.
What does the design as a support bearing mean in the NJ version?
An NJ-type bearing has two fixed flanges on the outer ring and one fixed flange on the inner ring. This allows it to support the shaft axially in one direction, whilst axial movement is possible in the other direction. This characteristic helps to compensate for changes in the shaft’s length caused by heating.
What is the temperature range for which the NJ2313 -E-XL-TVP2 bearing is designed?
The permissible operating temperature range is from -30 to +120 degrees. This thermal operating range is essentially limited by the polyamide cage and the lubricant used. Within this range, the dimensional stability of the cage and the single-row cylindrical rollers is maintained.
What is the clearance and tolerance class of this rolling bearing?
Manufactured with standard radial bearing clearance, the component is suitable for typical operating conditions in mechanical engineering. It is manufactured to tolerance class P0 or PN (comparable to ABEC 1). This standard tolerance meets the common accuracy requirements for industrial machine components.
How is this cylindrical roller bearing lubricated?
As this is an open bearing with no integrated seals and no groove or lubrication hole in the outer ring, lubrication must be applied externally via the housing. Depending on the operating conditions, you can use grease or lubricating oil. A clean supply of lubricant protects the raceways from wear.
Why can the inner ring be removed from one side?
The ability to disassemble the bearing from one side simplifies its installation and removal. The inner ring and outer ring assembly can be pressed onto the shaft and housing separately before the two components are joined together. This helps to prevent damage to the raceways and rolling elements during installation.
