Cylindrical Roller Bearings FAG NJ236 -E-M1
The FAG NJ236 -E-M1 cylindrical roller bearing, with a 180 mm bore, brass cage and support bearing function, offers high radial load-carrying capacity for demanding industrial applications.
The single-row cylindrical roller bearing NJ236 -E-M1 from FAG is designed as a support bearing and, in addition to high radial loads, also accommodates axial forces from one direction. With a bore of 180 mm, an outer diameter of 320 mm and a width of 52 mm, this version is designed for heavy-duty shaft mountings. The open roller bearing features a solid brass cage and operates within a temperature range of -30 to +150 degrees Celsius.
What is the NJ236 -E-M1 cylindrical roller bearing suitable for in industrial applications?
This radial roller bearing is particularly suitable for bearing arrangements where heavy radial loads act on the shaft and axial forces must also be supported. Due to the NJ design, the outer ring has two fixed flanges, whilst the inner ring has one fixed flange. This design allows for axial displacement in one direction and compensates for temperature-induced changes in the shaft’s length without straining the raceway. At the same time, the inner ring flange serves as a single-sided axial guide.
What are the advantages of this support bearing’s brass cage?
The designation letter M1 refers to a solid brass cage which guides the cylindrical rollers and withstands high vibrations and shock loads. Under heavy dynamic loads, brass offers high strength and good emergency running properties compared to standard sheet metal cages. The inner ring can be removed from one side for assembly, which facilitates separate pressing onto the shaft and housing. The tolerance class P0/PN corresponds to ABEC 1 and meets standard industrial requirements with normal radial clearance.
What are the dimensions of the NJ236 -E-M1 cylindrical roller bearing?
The bearing has an inside diameter of 180 mm, an outside diameter of 320 mm and a width across flats of 52 mm. These standardised key dimensions enable it to be fitted precisely into housing bores and onto shafts of the same nominal size.
What does the ‘NJ’ design designation mean for this roller bearing?
The NJ design denotes a support bearing with two fixed flanges on the outer ring and one fixed flange on the inner ring. This enables the bearing to accommodate radial loads and axial forces from one direction, whilst allowing axial displacement in the opposite direction to be freely compensated.
What is the temperature range for which the cylindrical roller bearing is designed?
The permissible operating range is between -30 and +150 degrees Celsius. As this is an open bearing without integrated sealing washers, the actual thermal operating limit is determined primarily by the external lubricant used and the environmental sealing.
What is the purpose of tolerance class P0 or ABEC 1?
Tolerance class P0/PN, also known internationally as ABEC 1, defines the standard accuracy for dimensional and running characteristics. It is suitable for the vast majority of general-purpose industrial drives and ensures compliance with concentricity requirements within standard manufacturing tolerances.
Why is the inner ring removable on this bearing?
The split design allows the inner ring and outer ring, together with the roller set, to be fitted separately onto the shaft and into the housing. This considerably simplifies assembly procedures in confined spaces and reduces the risk of the components becoming misaligned during installation.
What type of lubrication does the open cylindrical roller bearing require?
As an open-type bearing without seals, the bearing is supplied with oil or grease depending on the operating environment. The surrounding structure therefore requires a suitable external seal to prevent the lubricant from escaping and dirt particles from entering.
