Cylindrical Roller Bearings FAG NU236 -E-XL-M1-C3
The FAG NU236 -E-XL-M1-C3 cylindrical roller bearing, measuring 180 x 320 x 52 mm and featuring a brass cage, offers a high radial load capacity for industrial applications.
The NU236 -E-XL-M1-C3 cylindrical roller bearing is a single-row radial roller bearing from FAG with a 180 mm bore, 320 mm outer diameter and 52 mm width. Due to the line contact between the cylindrical rollers and the raceways, the design can accommodate very heavy radial loads. The bearing is of an open design and has no contact seals. The outer ring is designed without a lubrication groove, whilst the tolerances correspond to class P0 or ABEC 1.
For which operating conditions is the NU236 -E-XL-M1-C3 cylindrical roller bearing suitable?
This non-locating bearing is designed to support purely radial forces and allows for free longitudinal compensation of shafts. As the inner ring can be removed from both sides, the bearing compensates for operational thermal expansion directly within the rolling element set. Typical applications include rigid mounting arrangements with high radial forces, where seals fitted to the housing and external lubrication systems provide the lubricant supply.
What are the distinctive features of the brass cage and the C3 clearance?
The M1 design features a solid brass cage which guides the rollers precisely, even under high acceleration or vibration. Compared to sheet metal cages, brass offers damping properties and is wear-resistant. The increased radial clearance (C3) counteracts bearing stress should operational temperature differences occur or tight fits be selected for the shaft and housing. The permissible temperature range is from -30 to +150 degrees Celsius.
What are the distinctive features of the NU design in the NU236 -E-XL-M1-C3 cylindrical roller bearing?
The NU design features two fixed flanges on the outer ring, whilst the inner ring is flangeless and can be removed from either side. As a result, the bearing functions purely as a non-locating bearing. It accommodates radial loads only and allows for axial displacement of the shaft relative to the housing within the bearing.
What are the dimensions of the NU236 -E-XL-M1-C3 cylindrical roller bearing?
The bearing has an inside diameter of 180 mm, an outside diameter of 320 mm and a width of 52 mm. These main dimensions define the installation space required on the shaft and in the housing bore.
What does the suffix C3 mean for this cylindrical roller bearing?
The designation C3 indicates an increased radial bearing clearance compared with the standard version. The internal clearance between the rollers and raceways is greater. This ensures smooth running without excessive preload, even in the event of operational heating or tight fits.
What material is the M1 cage made of?
The suffix M1 indicates a solid brass cage. Brass cages offer high mechanical strength and are suitable for demanding operating conditions involving shock loads or vibrations, as they reduce friction and wear on the rolling elements.
What is the permissible temperature range for the NU236 cylindrical roller bearing?
The specified temperature range is between -30 and +150 degrees Celsius. Within these limits, the bearing components and the brass cage retain their dimensional stability. When designing the system, a lubricant must be selected that covers this temperature range.
What type of lubrication does the open cylindrical roller bearing require?
As the bearing is of an open design and has neither seals nor lubrication holes in the outer ring, the surrounding housing must be sealed. Grease or lubricating oil is supplied directly via the machine’s housing design.
