Cylindrical Roller Bearings FAG NJ2312 -E-XL-TVP2
The FAG NJ2312 -E-XL-TVP2 cylindrical roller bearing (60x130x46 mm) is a single-row support bearing with a polyamide cage designed for high radial loads.
The FAG NJ2312 -E-XL-TVP2 cylindrical roller bearing is suitable as a single-row rolling bearing for demanding industrial applications. With a bore of 60 mm, an outside diameter of 130 mm and a width of 46 mm, this radial roller bearing can withstand high radial loads. As an open bearing without a seal, the unit is designed for operating temperatures ranging from -30 to +120 degrees. The design complies with tolerance class P0/PN (ABEC 1) and has standard radial clearance.
What is the NJ2312 -E-XL-TVP2 cylindrical roller bearing suitable for?
This single-row radial roller bearing is primarily used in bearing arrangements that are subjected to high transverse forces and require single-sided axial guidance. Thanks to the line contact of the cylindrical rollers, the component offers high radial stiffness. Typical applications are found in general mechanical engineering for shaft mountings with single-sided axial load support. As the inner ring is removable from one side, the bearing can be fitted separately in confined installation spaces.
What is the function of the NJ design with a polyamide cage?
The NJ design is a classic support bearing. The outer ring has two fixed flanges, whilst the inner ring has a single flange. As a result, the bearing accommodates not only radial forces but also axial loads from one direction, whilst allowing axial displacement in the opposite direction. The integrated polyamide cage guides the rollers quietly and is designed for operating temperatures ranging from -30 to +120 degrees. External lubrication must be provided.
What are the main dimensions of the NJ2312 -E-XL-TVP2 cylindrical roller bearing?
With an internal diameter of 60 mm, an external diameter of 130 mm and a width of 46 mm, the bearing fits onto corresponding shafts and into suitable housing bores with these nominal dimensions.
What does the ‘NJ’ design designation mean for this cylindrical roller bearing?
As a support bearing, this design features two fixed shoulders on the outer ring and one fixed shoulder on the inner ring. This allows the bearing to absorb axial forces in one direction, whilst allowing axial displacement of the shaft within the bearing in the opposite direction.
What properties does the polyamide cage offer?
A polyamide cage is characterised by its elastic properties, low mass and low-friction guidance of the rolling elements. The cage is designed for an permissible operating temperature range of -30 to +120 degrees.
What are the lubrication requirements for this bearing?
As an open bearing without integrated seals, the component requires an external supply of grease or oil. An external seal in the surrounding housing structure is required to retain the lubricant within the bearing and prevent the ingress of dirt.
What are the bearing clearance and tolerance class for this product?
Manufactured with standard radial bearing clearance and to tolerance class P0/PN or ABEC 1, this bearing meets the usual precision requirements for industrial applications. The manufacturing accuracy is designed to ensure reliable operation with standardised shaft and housing fits.
Why is the inner ring on this model removable on one side only?
The separable inner ring makes installation and removal considerably easier. The inner and outer rings can be fitted separately onto the shaft and into the housing before the unit is assembled. This also simplifies subsequent maintenance and inspection procedures at the bearing location.
