Cylindrical Roller Bearings FAG NJ215 -E-XL-TVP2
The FAG NJ215 -E-XL-TVP2 cylindrical roller bearing, measuring 75 × 130 × 25 mm, serves as a single-row support bearing with a polyamide cage designed to withstand high radial loads.
The NJ215 -E-XL-TVP2 cylindrical roller bearing is a single-row roller bearing with a 75 mm bore, an outer diameter of 130 mm and a width of 25 mm. The manufacturer, FAG Rolling Bearings, produces this version with standard radial clearance and in tolerance class P0/PN or ABEC 1. As this is an open rolling bearing without seals, lubrication is provided by the surrounding housing structure. The outer ring has no groove and no lubrication bore.
What loads does the NJ215 -E-XL-TVP2 cylindrical roller bearing accommodate as a support bearing?
This roller bearing is used where high radial loads are present and the bearing is required to compensate for axial displacement in one direction. Due to its NJ design, the bearing functions as a support bearing. It accommodates axial forces in one direction, whilst the inner ring remains removable from one side. This feature facilitates the separate installation of the inner and outer rings on shafts and housings.
What is the function of the TVP2 polyamide cage?
The suffix TVP2 denotes a polyamide cage which guides the cylindrical rollers and prevents direct contact between the rolling elements. The cage has a low weight, which reduces inertial forces during operation. The permissible temperature range is between –30 and +120 degrees. As the bearing is of an open design, lubrication and protection against contamination must be provided by the surrounding structure.
What are the dimensions of the NJ215 -E-XL-TVP2 cylindrical roller bearing?
The bearing has an internal diameter of 75 mm, an external diameter of 130 mm and a width of 25 mm. These standardised key dimensions enable it to be fitted precisely into the corresponding housing bores and onto suitable shaft seats.
What does the ‘NJ’ design designation mean for this roller bearing?
The NJ design features two fixed flanges on the outer ring and one fixed flange on the inner ring. This enables the cylindrical roller bearing to function as a support bearing, which absorbs axial loads in one direction whilst allowing the shaft to move in the opposite direction. The inner ring can be removed from one side.
What material is the TVP2 cage made of?
The abbreviation TVP2 refers to a polyamide cage. The material is characterised by its low weight, which keeps the inertial forces in the rolling element guidance to a minimum. The permissible temperature range for the bearing with this polyamide cage is between -30 and +120 degrees.
What is the clearance of the NJ215 -E-XL-TVP2 cylindrical roller bearing?
This bearing is manufactured with standard radial clearance. This standard radial clearance is intended for typical operating temperatures and conventional fit designs, where neither excessive operational heating nor extreme press fits reduce the radial clearance to an unacceptable level.
How is the open bearing lubricated and sealed?
The bearing has no integral sealing washers and the outer ring has no lubrication bore. The supply of lubricant – whether grease or oil – and protection against dirt and moisture must therefore be provided entirely by external seals and feed systems incorporated into the housing design.
What is the tolerance class of this roller bearing?
The cylindrical roller bearing complies with tolerance class P0 or PN, which corresponds to the ABEC 1 standard in the US. This standard tolerance meets the usual accuracy requirements for shaft and housing fits in industrial applications.
