Cylindrical Roller Bearings FAG NJ326 -E-M1
The FAG NJ326 -E-M1 cylindrical roller bearing, with a 130 mm bore, brass cage and NJ design, serves as a support bearing for high radial loads.
The FAG NJ326 -E-M1 cylindrical roller bearing is a single-row rolling bearing designed for demanding industrial applications. With a bore of 130 mm, an outer diameter of 280 mm and a width of 58 mm, this roller bearing can accommodate very high radial loads. The integrated brass cage guides the cylindrical rollers during operation. Designed as an open bearing, this version can be specifically integrated into an existing lubrication system via the machine housing.
What is the NJ326 -E-M1 cylindrical roller bearing suitable for in operation?
This cylindrical roller bearing is primarily used in industrial drives and gearboxes where significant radial forces act on the shaft. Due to its NJ design, the bearing functions as a support bearing: the outer ring has two fixed flanges, whilst the inner ring has one fixed flange. As a result, the unit absorbs radial forces and also guides the shaft in an axial direction. In the opposite direction, the design allows for axial displacement, thereby compensating for thermal length changes.
What advantages do the brass cage and the NJ design offer during installation?
In the NJ design, the inner ring can be removed from one side. This simplifies installation, as the inner and outer rings can be fitted separately onto the shaft and housing. The solid brass cage (designation M1) is characterised by high strength. Designed with standard radial bearing clearance and the standard tolerance class P0/PN (ABEC 1), the component covers a temperature range from –30 to +150 degrees Celsius.
What are the dimensions of the NJ326 -E-M1 cylindrical roller bearing?
The bearing has an internal diameter of 130 mm, an external diameter of 280 mm and a width of 58 mm. These standardised dimensions enable it to be fitted precisely into housings and shaft seats of the corresponding sizes.
What does the ‘NJ’ design designation mean for this cylindrical roller bearing?
The abbreviation NJ denotes a thrust bearing. The outer ring has two integral flanges and the inner ring has a fixed flange. As a result, the bearing supports the shaft in one axial direction, whilst allowing for axial movement in the other direction to compensate for thermal expansion.
What are the features of the brass cage?
The brass cage, identified by the suffix M1, is characterised by its high strength. It guides the rollers stably within the rolling element ring, even under varying accelerations and increased loads.
What is the operating temperature range for the NJ326 -E-M1?
The bearing is designed for operating temperatures ranging from -30 to +150 degrees Celsius. In addition to the bearing materials, the thermal stability of the lubricant used is always a decisive factor in determining the actual operating limit.
Why is the bearing supplied in an open design?
The open design, which does not feature integrated sealing washers, allows for the direct circulation of lubricating oil or grease from the surrounding machinery system. It is suitable for installation locations where external housing seals already provide protection against contamination.
What does the tolerance class P0/PN or ABEC 1 mean?
This classification corresponds to the conventional standard tolerance for dimensional and running accuracy in accordance with international standards. It is the established standard for the majority of industrial shaft bearings that do not require increased precision.
