Cylindrical Roller Bearings FAG NJ306 -E-XL-TVP2-C3
The FAG NJ306 -E-XL-TVP2-C3 cylindrical roller bearing, with a 30 mm bore and C3 clearance, offers a high-load-capacity solution for radial loads with an axial guidance function.
The single-row cylindrical roller bearing NJ306 -E-XL-TVP2-C3 from FAG Rolling Bearings accommodates high radial forces and provides axial guidance for shafts in one direction. With key dimensions of a 30 mm bore diameter, 72 mm outer diameter and 19 mm width, this open bearing complies with tolerance class P0/PN or ABEC 1. It is suitable for demanding industrial applications within a temperature range of -30 to +120 degrees. Manufacturers and workshops appreciate the precise manufacture of the rolling element guidance.
What is the NJ306 -E-XL-TVP2-C3 cylindrical roller bearing suitable for as a support bearing?
When used as a support bearing, this design absorbs high radial forces and supports axial forces from one direction. The inner ring can be removed from one side, allowing for axial displacement and facilitating installation. Typical applications include general mechanical engineering, gearboxes or shaft guides where components are subject to thermal linear expansion.
What is the function of the polyamide cage and the C3 clearance?
The increased C3 clearance compensates for operational heating and fit allowances without unduly reducing the bearing clearance. The TVP2 polyamide cage guides the cylindrical rollers quietly and flexibly, which dampens dynamic shock loads. When selecting this bearing, designers and maintenance engineers should bear in mind that this open bearing requires a housing-side seal as well as a suitable lubrication supply.
What are the dimensions of the NJ306 -E-XL-TVP2-C3 cylindrical roller bearing?
This cylindrical roller bearing has an inner diameter of 30 mm, an outer diameter of 72 mm and a width of 19 mm. This single-row roller bearing has an outer ring without a lubrication bore or groove. As the inner ring can be removed from one side, the bearing can be fitted separately onto the shaft and housing during installation.
What does the ‘NJ’ design designation mean for this cylindrical roller bearing?
The NJ design denotes a cylindrical roller bearing that functions as a support bearing. The outer ring has two solid flanges, whilst the inner ring has one solid flange. As a result, the bearing transmits radial forces and absorbs axial forces from a defined direction, whilst allowing axial displacement in the opposite direction.
What does the bearing clearance specification C3 stand for?
The suffix C3 indicates a slightly increased radial bearing clearance compared with the standard version. This greater clearance prevents the rollers from seizing up due to operational heating or tight fits on the shaft. As a result, the bearing operates reliably even when there are temperature differences between the inner and outer rings.
What features does the built-in TVP2 cage offer?
The designation TVP2 refers to a solid polyamide cage. This material is characterised by its low weight, elastic properties and smooth running. The cage guides the cylindrical rolling elements with low friction. Please note that the permissible operating temperature range for the bearing is from -30 to +120 degrees.
How is the NJ306 open cylindrical roller bearing sealed and lubricated?
As the NJ306 cylindrical roller bearing is designed as an open bearing without integrated sealing washers, the bearing housing requires external sealing. This protects the rolling element system against the ingress of dirt and moisture. Lubrication is provided either by grease or oil via the surrounding housing structure.
What is the operating temperature range for the bearing?
The permissible temperature range for this roller bearing is between -30 and +120 degrees. This range is limited, amongst other things, by the material of the polyamide cage. For use within these limits, a lubricant must be selected that maintains its viscosity and lubricating properties throughout the entire temperature range.
