Cylindrical Roller Bearings FAG NU310 -E-M1
The NU310 -E-M1 cylindrical roller bearing from FAG is an open, non-locating bearing with a brass cage, designed to withstand high radial loads with dimensions of 50x110x27 mm.
The NU310 -E-M1 cylindrical roller bearing from FAG Rolling Bearings is designed as a single-row radial roller bearing for demanding industrial applications. Thanks to the line contact between the rollers and raceways, this design can withstand high radial loads. With dimensions of 50 mm bore, 110 mm outside diameter and 27 mm width, the open bearing operates within a temperature range of -30 to +150 degrees Celsius.
What is the NU310 -E-M1 cylindrical roller bearing suitable for?
This type of bearing is primarily used where high radial forces occur and, at the same time, axial length changes in the shaft need to be compensated for. In industrial bearing arrangements, the NU design functions as a classic non-locating bearing. As the outer ring has fixed flanges whilst the inner ring is flangeless, the shaft and housing can move axially relative to one another without causing internal stresses.
What are the advantages of the free-end bearing design and the brass cage?
The solid brass cage guides the rolling elements with dimensional stability even under vibration, varying speeds and thermal stress. The NU design allows the inner ring to be removed from both sides. This facilitates the separate installation of both bearing rings. Manufactured to the standard tolerance class P0/PN (ABEC 1) and with standard radial clearance, the component fits into existing fitting systems. As the bearing is open, lubrication is provided via oil or grease supplied by the customer.
What are the main dimensions of the NU310 -E-M1 cylindrical roller bearing?
The bearing has an inner diameter of 50 mm, an outer diameter of 110 mm and a width of 27 mm. These standardised mounting dimensions enable it to be fitted precisely into standardised housings and onto corresponding shaft seats.
What are the distinctive features of the NU design in cylindrical roller bearings?
In the NU design, the outer ring has two fixed guide flanges, whilst the inner ring is manufactured without flanges. This allows the inner ring to be removed from either side. The bearing acts purely as a support bearing and compensates for temperature-induced linear expansion of the shaft without constraint within the bearing.
What is the advantage of the brass cage in this version?
The brass cage is characterised by high mechanical strength and heat resistance. It is particularly suitable for applications involving vibrations, shock loads or rapid changes in speed, as it guides the rollers whilst maintaining their shape and minimising wear.
What is the bearing clearance and tolerance class of the bearing?
This component is designed with standard radial bearing clearance (CN), which is suitable for standard operation without extreme temperature gradients between the shaft and the housing. The manufacturing accuracy complies with tolerance class P0/PN or ABEC 1 for standard industrial applications.
How is the open bearing lubricated and sealed?
As the cylindrical roller bearing is supplied from the factory without integrated sealing washers, sealing is provided by the surrounding housing structure, for example by shaft seals or labyrinth seals. Depending on the operating requirements and operating temperature, suitable lubricating oils or greases can be used for lubrication.
Within what temperature range can the bearing be operated?
The permissible operating range is from -30 to +150 degrees Celsius. Both the dimensionally stable bearing rings and the material of the brass cage are designed for this operating range, provided that the lubricant used is approved for the relevant operating temperatures.
