Cylindrical Roller Bearings FAG NJ332 -E-M1
The FAG NJ332 -E-M1 cylindrical roller bearing, measuring 160 × 340 × 68 mm, offers high radial load capacity and single-sided axial support.
The FAG NJ332 -E-M1 cylindrical roller bearing is a single-row radial roller bearing designed for heavy-duty industrial applications. It has a bore of 160 mm, an outer diameter of 340 mm and a width of 68 mm. The NJ design features two fixed flanges on the outer ring and one fixed flange on the inner ring. This enables the bearing to withstand high radial forces and guide the shaft in an axial direction.
What is the NJ332 -E-M1 cylindrical roller bearing suitable for?
This roller bearing is primarily used as a support bearing in bearing arrangements where, in addition to significant radial loads, unilateral guiding forces are also present. In the opposite direction, the design allows for axial displacement between the shaft and the housing, which compensates for thermal length changes without constraint. The solid brass cage guides the cylindrical rollers and is well suited to demanding operating conditions involving vibrations or shock loads.
What are the advantages of the NJ design and the brass cage?
The NJ design allows for the separate installation of the inner and outer rings, as the inner ring can be removed from one side. This facilitates the assembly of larger sub-assemblies. As an open bearing, this design can be specifically integrated into the machine’s lubrication circuit. The permissible temperature range is from –30 to +150 degrees Celsius. The bearings are manufactured to the standard tolerance class P0/PN (ABEC 1) with standard radial clearance.
What are the key features of the NJ332 -E-M1 cylindrical roller bearing?
A single-row radial roller bearing with a 160 mm bore, 340 mm outer diameter and 68 mm width. The NJ design features two flanges on the outer ring and one flange on the inner ring, enabling it to withstand radial forces and lock the shaft axially in one direction.
What does the ‘NJ’ design designation mean for this cylindrical roller bearing?
The designation NJ describes the flange arrangement. The outer ring has two fixed guide flanges, whilst the inner ring has one flange. As a result, the bearing unit functions as a support bearing with single-sided guidance, whilst axial displacement in the opposite direction is still permitted.
What is the function of the M1 brass cage?
The solid brass cage guides the cylindrical rollers securely along their raceways. It is characterised by high dimensional stability under vibrations, accelerations and elevated operating temperatures, and is suitable for demanding operating conditions.
What is the clearance and tolerance class of this bearing?
This version is manufactured to the standard tolerance class P0/PN, which corresponds to the international ABEC 1 standard. The radial bearing clearance is also within the standard range and is designed for standard fits and moderate temperature differences between the inner and outer rings.
What temperature range is the bearing suitable for?
The open bearing is specified for operating temperatures ranging from -30 to +150 degrees Celsius. As no seals are fitted at the factory, it is primarily the lubricant applied on site that determines the exact thermal limits of the bearing assembly during operation.
How is the cylindrical roller bearing lubricated?
As this is an open bearing with no groove and no lubrication hole in the outer ring, lubrication is provided by the surrounding structure. Depending on the machine design, you should lubricate the bearing via an oil bath, a recirculating lubrication system or by regularly re-lubricating it with a suitable rolling-element bearing grease.
