Cylindrical Roller Bearings FAG NJ314 -E-XL-TVP2
The FAG NJ314 -E-XL-TVP2 single-row cylindrical roller bearing, measuring 70x150x35 mm, offers high radial load-carrying capacity and axial guidance in one direction.
This FAG NJ314 -E-XL-TVP2 cylindrical roller bearing is used in demanding industrial drives. As a radial roller bearing, it primarily absorbs heavy radial forces and provides axial guidance in one direction. The combination of solid bearing rings and cylindrical rollers ensures high rigidity within the system. The integrated polyamide cage keeps the rolling elements spaced apart and promotes quiet running.
What loads can the NJ314 -E-XL-TVP2 cylindrical roller bearing withstand?
Its use is recommended for high radial loads on the bearing mounting. Due to its NJ design, the component functions as a support bearing. In addition to the primary radial forces, it also accommodates one-sided axial forces, whilst compensating for thermally induced length changes of the shaft in the opposite direction. Typical applications include rigid shaft mountings with single-sided guidance in mechanical and plant engineering.
What properties do the polyamide cage and NJ design offer?
The material of the polyamide cage is characterised by low friction and low weight. The bearing is designed for an operating temperature range of –30 to +120 degrees. As the inner ring can be removed from one side, the open bearing can be fitted separately. During installation, care must be taken to ensure the fixed flange on the inner ring is correctly aligned so that the desired axial guidance direction is maintained. Lubrication is provided by the surrounding housing.
What are the key features of the NJ314 -E-XL-TVP2 cylindrical roller bearing?
As a single-row radial roller bearing, this version has the following main dimensions: 70 mm bore, 150 mm outside diameter and 35 mm width. Two fixed flanges on the outer ring and one fixed flange on the inner ring enable the bearing to accommodate axial forces in one direction.
What is the function of the NJ design as a support bearing?
In the NJ design, the inner ring has a solid flange on one side only. As a result, the bearing supports the shaft axially in one direction. In the opposite direction, it allows for axial displacement to accommodate linear expansion of the shaft without causing internal stresses.
What are the features of the TVP2 polyamide cage?
The cage, designated TVP2, is made of polyamide and is designed as a solid window cage. This material reduces inertial forces and ensures smooth running. The permissible operating temperature range is between -30 and +120 degrees.
What is the clearance and tolerance class of this bearing?
Manufactured with standard radial bearing clearance (Class CN or PN), the bearing complies with the P0 standard class for dimensional and running tolerances (equivalent to ABEC 1). This design is suitable for common industrial applications at normal operating temperatures.
How is the NJ314 open cylindrical roller bearing lubricated?
As this model is manufactured without integrated seals, the bearing seat must be sealed externally via the housing design. Lubrication can be carried out either with grease or via an oil circuit. The outer ring has no lubrication groove or lubrication bore, which is why lubricant is supplied from the side.
Can the cylindrical roller bearing be dismantled for fitting?
The inner ring of this bearing can be removed from one side. This enables fitters to press the inner and outer rings onto the shaft and housing separately. This method makes the installation of fixed and loose bearing seats considerably easier.
