Cylindrical Roller Bearings FAG NU330 -E-M1
The NU330 -E-M1 cylindrical roller bearing from FAG Wälzlager is a single-row non-locating bearing with a brass cage and main dimensions of 150 × 320 × 65 mm, designed for high radial loads.
The NU330 -E-M1 cylindrical roller bearing is a single-row roller bearing designed for demanding mechanical assemblies in which primarily pure radial forces are at work. Designed as an open bearing, this construction allows lubrication via the customer’s own lubrication system. With a bore of 150 mm, an outside diameter of 320 mm and a width of 65 mm, the bearing can accommodate considerable transverse forces. Manufactured by FAG Wälzlager, its dimensional accuracy complies with tolerance class P0/PN or ABEC 1. It operates within a temperature range of -30 to +150 degrees.
Where is the NU330-E-M1 cylindrical roller bearing typically used?
Typical applications include heavy-duty shaft mountings in mechanical and plant engineering, where axial length changes caused by thermal expansion or operational conditions must be compensated for. Due to its design as a floating bearing, the shaft moves freely relative to the housing within the bearing. The line contact of the cylindrical rollers gives the bearing considerable radial stiffness. Installation is particularly recommended where high continuous radial loads occur and separate axial bearings handle the axial forces.
What are the distinctive features of the free-end bearing design with a brass cage?
The inner ring, which can be removed from both sides, considerably facilitates the assembly and disassembly of the components. The inner and outer rings can be mounted separately onto the shaft and housing before the unit is assembled. The integrated brass cage guides the rolling elements with low vibration and is suitable for demanding dynamic conditions. As the outer ring is designed without a groove or lubrication bore, the lubricant is supplied via the lateral clearances in the housing design. With normal radial bearing clearance, the operating clearance remains stable in standard installation situations.
What are the dimensions of the NU330 -E-M1 cylindrical roller bearing?
The main dimensions are 150 mm internal diameter (bore), 320 mm external diameter and 65 mm width. These standardised dimensions correspond to the NU330 series. With these dimensions, the single-row roller bearing is suitable for installation on robust industrial shafts and heavy-duty drive shafts.
What is the function of the NU design as a non-locating bearing?
In the NU design, the outer ring has two fixed guide flanges, whilst the inner ring has no flanges and can be removed from either side. This allows the bearing to permit unimpeded axial movement of the shaft relative to the housing. It accommodates radial loads only and prevents thermally induced stresses in the drive train.
What temperature range is the bearing suitable for?
The permissible operating range is between -30 and +150 degrees Celsius. Both the rolling elements and the robust brass cage are designed to withstand these operating temperatures. The key to ensuring reliable operation at the thermal limits is the selection of a lubricant that provides the required lubrication performance within this temperature range.
What are the advantages of the built-in brass cage?
A solid brass cage guides the cylindrical rollers with precision and effectively dampens mechanical vibrations. The material is characterised by good run-on properties and high strength under dynamic acceleration, making it suitable for demanding applications.
How should the open cylindrical roller bearing be lubricated?
As the model is designed as an open bearing without integrated sealing washers, the lubricant is supplied from the outside. It can be operated using either lubricating oil or grease. To prevent contamination and loss of lubricant, seals must be fitted by the customer in the surrounding bearing housing.
What is the significance of the standard radial bearing clearance for this bearing?
The marking indicates that the bearing has been manufactured with standard internal clearance between the rollers and raceways. This standard clearance is sufficient to prevent the rolling elements from jamming under normal fit conditions and at moderate operating temperatures. No special adjustments to the shaft fit are required for this.
