Cylindrical Roller Bearings FAG NJ230 -E-M1
The FAG NJ230 -E-M1 single-row cylindrical roller bearing with a brass cage can accommodate high radial loads and unilateral axial forces with dimensions of 150 × 270 × 45 mm.
This open NJ230 -E-M1 cylindrical roller bearing from FAG is designed for industrial applications involving high radial forces. Thanks to the line contact between the rolling elements and the raceways, the bearing offers high rigidity. The NJ design acts as a support bearing, enabling it to accommodate axial forces. As the bearing housing is open, the roller bearing can be flexibly integrated into centralised oil or grease lubrication systems.
What loads is the NJ230 -E-M1 cylindrical roller bearing designed to withstand?
The bearing is particularly suitable where shaft guides must support not only significant radial loads but also unilateral axial forces. Thanks to the inner ring being removable from one side, the design is suitable for installation situations requiring separate assembly of the inner and outer rings. The permissible temperature range of –30 to +150 degrees allows it to be used even under thermally demanding conditions.
What is the function of the brass cage in the NJ design?
The solid brass cage (designation M1) provides the NJ230 -E-M1 cylindrical roller bearing with mechanical stability under vibrations and shock loads. When designing the bearing arrangement, it must be taken into account that the bearing has standard radial clearance and is manufactured to tolerance class P0/PN (corresponding to ABEC 1). As the outer ring is designed without a lubrication groove or lubrication bore, the lubricant is supplied from the side via the bearing housing.
What are the distinctive features of the NJ design in the NJ230 -E-M1 cylindrical roller bearing?
The NJ design features two fixed flanges on the outer ring and one fixed flange on the inner ring. This allows the roller bearing to function as a support bearing that guides shafts in the axial direction, whilst still permitting axial movement in the opposite direction. Furthermore, the inner ring can be removed from one side to facilitate assembly.
What are the dimensions of the NJ230 -E-M1 cylindrical roller bearing?
The bearing has an internal diameter of 150 mm, an external diameter of 270 mm and a width of 45 mm. These key dimensions determine the installation space required on the shaft and within the bearing housing.
What is the function of the M1 brass cage?
The brass cage guides the cylindrical rollers precisely and maintains a uniform distance between them. The solid brass cage is highly resistant to vibrations and supports the rollers under impact loads.
What is the temperature range within which the bearing can be used?
The permissible temperature range for this rolling bearing is between -30 and +150 degrees. Within this range, the components retain their dimensional stability. The actual upper temperature limit during operation depends largely on the suitability of the selected lubricant.
What features does the open version of the cylindrical roller bearing offer?
As an open roller bearing, this design has no integrated seals. This allows lubricating oil or grease to pass freely within enclosed housing assemblies. Protection against contaminants and moisture is provided by the surrounding structure.
What are the bearing clearance and tolerance class of the NJ230 -E-M1?
The roller bearing is manufactured with a standard radial clearance, suitable for standard fit conditions and typical operating conditions. It is manufactured to tolerance class P0/PN (equivalent to ABEC 1), which specifies the permissible dimensional and runout tolerances.
