Cylindrical Roller Bearings FAG NU328 -E-XL-TVP2
The FAG NU328 -E-XL-TVP2 cylindrical roller bearing is an open idler bearing designed to withstand high radial loads and measures 140 x 300 x 62 mm.
The NU328 -E-XL-TVP2 cylindrical roller bearing is a single-row radial roller bearing from FAG designed for demanding industrial applications. The line contact of the cylindrical rollers enables it to withstand high radial loads whilst maintaining a compact design. With dimensions of 140 mm bore, 300 mm outside diameter and 62 mm width, the design functions as a non-locating bearing. The design complies with standard tolerance P0 or ABEC 1.
What is the NU328 -E-XL-TVP2 cylindrical roller bearing suitable for?
This single-row cylindrical roller bearing is primarily used where heavy radial loads are present and axial changes in shaft length need to be compensated for. Typical applications can be found in general mechanical engineering as well as in demanding industrial shaft bearings. The open design without sealing washers allows for flexible integration into existing lubrication systems using oil or grease. As the outer ring has no groove or lubrication bore, the lubricant is supplied from the side via the bearing housing.
What is the function of the NU design with a polyamide cage?
The NU design features two fixed flanges on the outer ring, whilst the inner ring is flangeless and can be removed from both sides. This design allows for unrestricted axial displacement of the shaft relative to the housing during operation. Furthermore, the separable inner ring facilitates the separate installation of both bearing rings. The integrated polyamide cage (TVP2) guides the rollers quietly and flexibly. The bearing operates with standard radial clearance within a temperature range of -30 to +120 degrees Celsius.
What are the distinctive features of the NU328 -E-XL-TVP2 cylindrical roller bearing design?
The designation NU refers to a cylindrical roller bearing with two fixed flanges on the outer ring and a smooth, flangeless inner ring. The inner ring can be withdrawn from either side. This design acts purely as a non-locating bearing, thereby compensating for axial thermal expansion of the shaft within the bearing with minimal friction.
What are the dimensions of the NU328 bearing?
The bearing has an inside diameter of 140 mm, an outside diameter of 300 mm and a width across flats of 62 mm. These key dimensions determine the required bearing seats on the shaft and in the housing bore. The bearings are manufactured to the standard tolerance class P0 or ABEC 1.
What does the suffix ‘TVP2’ mean for this bearing?
The suffix TVP2 indicates a polyamide cage. This material is characterised by its low weight, elasticity and good running properties. It helps to ensure smooth guidance of the cylindrical rollers and is suitable for operating temperatures ranging from -30 to +120 degrees Celsius.
What is the clearance of the NU328 -E-XL-TVP2 cylindrical roller bearing?
The bearing is manufactured with standard radial bearing clearance. This clearance class covers typical operating conditions and standard fits in mechanical engineering. It refers to the radial clearance between the rollers and the raceways prior to installation and is reduced to the required operating clearance after press-fitting.
How is the open cylindrical roller bearing lubricated?
The bearing has an open design and has no integrated seals. Lubrication with oil or grease is tailored to the specific operating conditions. As the outer ring has no lubrication groove or bore, the lubricant is introduced into the bearing chamber from the side.
What is the operating temperature range for this bearing?
The permissible operating temperature range is between -30 and +120 degrees Celsius. This temperature range is limited primarily by the material of the polyamide cage. For reliable operation, a lubricant is recommended whose viscosity and composition are approved for this temperature range.
