Cylindrical Roller Bearings FAG NJ205 -E-XL-TVP2
The FAG NJ205 -E-XL-TVP2 cylindrical roller bearing, measuring 25x52x15 mm, withstands high radial loads and provides single-sided axial support for shafts.
The NJ205 -E-XL-TVP2 cylindrical roller bearing is a single-row radial roller bearing designed for industrial applications involving high radial loads. This open bearing has a bore of 25 mm, an outer diameter of 52 mm and a width of 15 mm. Thanks to the line contact of the cylindrical rollers, the design withstands high radial forces and transfers them to the housing.
When is the NJ205 -E-XL-TVP2 cylindrical roller bearing suitable as a support bearing?
This design is used where, in addition to radial forces, axial guiding forces occur in one direction. The NJ design features two fixed flanges on the outer ring and one fixed flange on the inner ring. As a result, the bearing acts as a support bearing that locks the shaft axially in one direction, whilst allowing free axial movement in the opposite direction. The inner ring can be removed from one side, which facilitates the separate assembly of both bearing rings.
What advantages does the TVP2 polyamide cage offer during operation?
The designation TVP2 indicates a polyamide cage. This cage is characterised by its low weight and elastic running characteristics, which reduce noise during operation. The bearing is designed for a temperature range of -30 to +120 degrees and has standard radial clearance in tolerance class P0/PN. As the outer ring is designed without a groove or lubrication bore, lubricant is supplied via the lateral end faces.
What are the distinctive features of the NJ205 cylindrical roller bearing design?
The NJ type has two fixed flanges on the outer ring and one fixed flange on the inner ring. It acts as a support bearing and accommodates radial loads as well as axial forces in one direction. In the opposite direction, the rolling bearing compensates for thermal linear changes in the shaft by allowing axial displacement.
What are the dimensions of the NJ205 -E-XL-TVP2 cylindrical roller bearing?
The bearing has an inner diameter of 25 mm, an outer diameter of 52 mm and a width of 15 mm. As the inner ring can be removed from one side, the bearing rings can be fitted separately onto the shaft and housing during assembly.
What does the suffix ‘TVP2’ mean in relation to this FAG bearing?
The suffix TVP2 indicates a polyamide cage. This material reduces the moving mass of the rotating components and ensures smooth running. The cage guides the cylindrical rollers and is suitable for operating temperatures ranging from -30 to +120 degrees.
How is the open cylindrical roller bearing sealed and lubricated?
This model has no integrated seals and is designed as an open bearing. The outer ring is manufactured without a lubrication groove or bore, which is why grease or oil must be supplied from the side. External seals must be fitted in the installation environment to protect the rolling elements from contamination.
What is the clearance in the NJ205 -E-XL-TVP2 cylindrical roller bearing?
The roller bearing is manufactured with a standard radial clearance and complies with the standard tolerance P0/PN or ABEC 1. This design is suitable for standard fit selections on shafts and housings, as well as for standard temperature differences between the inner and outer rings.
