Cylindrical Roller Bearings FAG NJ317 -E-XL-TVP2
The FAG NJ317 -E-XL-TVP2 cylindrical roller bearing, with dimensions of 85 × 180 × 41 mm, can accommodate high radial loads and unilateral axial loads.
The FAG NJ317 -E-XL-TVP2 cylindrical roller bearing is a single-row radial roller bearing for industrial applications. Due to the line contact between the cylindrical rollers and the raceways, this design can accommodate high radial loads. The manufacturer, FAG, fits this model with a lightweight polyamide cage. As an open rolling bearing without an integrated seal, it can be lubricated with either grease or oil via the surrounding structure.
What is the NJ317 -E-XL-TVP2 cylindrical roller bearing suitable for as a support bearing?
This bearing is used in shaft mountings that require axial guidance in one direction in addition to radial loading. In the NJ design, the outer ring has two solid flanges and the inner ring has one solid flange. The component acts as a support bearing and absorbs axial forces on one side. In the opposite direction, the design allows for axial displacement, thereby compensating for temperature-induced changes in the shaft’s length.
What characteristics does the TVP2 polyamide cage offer in operation?
The suffix TVP2 denotes a polyamide cage that is guided on the rolling elements. This material reduces the moving mass within the bearing and is characterised by its damping properties and elasticity. The permissible temperature range is from –30 to +120 degrees Celsius. For assembly and maintenance, the inner ring can be removed from one side, which allows the inner and outer rings to be fitted separately.
What are the main dimensions of the NJ317 -E-XL-TVP2 cylindrical roller bearing?
The bearing has a bore diameter of 85 mm, an outer diameter of 180 mm and a width of 41 mm. It is a single-row cylindrical roller bearing with standard tolerances in tolerance class P0 or ABEC 1. The outer ring has no groove and no lubrication bore.
What does the NJ design designation mean for cylindrical roller bearings?
The NJ design features two solid flanges on the outer ring and one solid flange on the inner ring. This enables the bearing to accommodate axial forces in one direction, acting as a support bearing. In the opposite direction, the design allows for axial displacement of the shaft relative to the housing.
What does the suffix ‘TVP2’ stand for in relation to this FAG bearing?
The abbreviation TVP2 refers to a polyamide cage. This type of cage is lightweight and ensures smooth bearing operation. The material is designed for use in a temperature range of between -30 and +120 degrees Celsius.
What is the clearance in the NJ317 -E-XL-TVP2 cylindrical roller bearing?
This roller bearing has a standard radial clearance. This clearance is suitable for standard mounting fits and typical operating temperatures, where there are no unusually large temperature differences between the shaft and the housing.
How is the open cylindrical roller bearing lubricated and sealed?
As this bearing is designed as an open model without sealing washers, sealing is provided by the surrounding housing structure. Lubrication can be carried out using grease or oil, depending on the operating conditions. The open design allows the lubricant to be supplied as required.
Can the bearing be dismantled for fitting?
The inner ring of this cylindrical roller bearing can be removed from one side. This allows for separate installation, so that the inner ring and outer ring, together with the set of rollers, can be fitted separately onto the shaft and into the housing bore.
