NJ412-XL-M1 FAG 60x150x35 mm - Single Row Cylindrical Roller Bearing

Technical Specifications

The listed technical values refer to the NJ412-XL-M1 FAG configuration. Catalogue load ratings and speeds are reference parameters and do not guarantee suitability for every operating condition.

What Does NJ412-XL-M1 Mean?

The complete designation NJ412-XL-M1 is essential for correct product identification.

Omitting the XL or M1 suffix may result in selecting a different bearing configuration with different technical characteristics.

Construction and Operating Principle

FAG NJ412-XL-M1 consists of an inner ring, an outer ring, a single row of cylindrical rollers, and a brass cage.

The outer ring incorporates two integral flanges that guide the rolling elements, while the inner ring has one flange.

This arrangement enables the bearing to accommodate radial loads and axial loads in one direction, subject to the permissible operating limits.

Unlike ball bearings, cylindrical roller bearings provide approximately line contact between the rolling elements and raceways.

This contact geometry enables the bearing to accommodate substantial radial loads.

Key construction features include:

• Single row of cylindrical rollers.

• Two integral flanges on the outer ring.

• One integral flange on the inner ring.

• Radial load-carrying capability.

• Axial load accommodation in one direction.

• Separable construction for easier installation.

• Two-piece brass cage, designation M1.

• Open design requiring suitable lubrication within the bearing arrangement.

An NJ bearing does not provide axial location of the shaft in both directions by itself.

X-life Design

The XL designation identifies Schaeffler's X-life performance design.

X-life incorporates optimised internal geometry, improved raceway and rolling element surface characteristics, and refined contact conditions.

For NJ412-XL-M1, the relevant performance characteristics are represented by the manufacturer's catalogue load ratings and operating limits.

The X-life designation should not be disregarded when identifying or replacing the bearing.

An older bearing version without the XL designation should not automatically be assumed to have identical load ratings or performance characteristics.

FAG NJ412-XL-M1 vs Other Variants

NJ and NU variants may share the same principal dimensions of 60x150x35 mm but perform different functions in a bearing arrangement.

Identical dimensions do not automatically mean that two bearings are interchangeable.

A C3 clearance variant should not replace a normal-clearance bearing without assessing operating clearance, shaft and housing fits, and temperature conditions.

Bearing Selection and Interchangeability

Before selecting FAG NJ412-XL-M1, verify the technical requirements of the application.

Important selection criteria include:

• Complete designation NJ412-XL-M1.

• Principal dimensions of 60x150x35 mm.

• Required bearing function: axial location in one direction.

• Normal radial internal clearance CN.

• Reduction of internal clearance after installation.

• Shaft and housing fits.

• Radial and axial operating loads.

• Rotational speed and lubrication conditions.

• Operating temperature and cooling conditions.

• Requirements associated with the M1 brass cage.

• Condition and geometry of shaft and housing shoulders.

When considering a replacement from another manufacturer, compare not only the principal dimensions but also the flange arrangement, internal clearance, cage construction, load ratings, and permissible speeds.

A bearing with the same bore diameter, outside diameter, and width may have different operating characteristics.

Alternative Designations and Reference Formats

Natural reference formats include:

• NJ412-XL-M1 FAG

• FAG NJ412-XL-M1

• NJ 412-XL-M1 FAG

• NJ412 XL M1 FAG

• FAG NJ412 XL M1

The designation NJ412-M1 FAG appears in older catalogue documentation. However, equivalence with the NJ412-XL-M1 X-life version requires verification of the technical characteristics of the specific bearing.

NKE NJ412-M may be considered as a dimensional and constructional alternative, subject to verification of its specifications and the requirements of the bearing arrangement.

These references must not be treated as automatically interchangeable products.

Applications of FAG NJ412-XL-M1

FAG NJ412-XL-M1 is intended for mechanical assemblies requiring radial load capacity and axial location of a shaft in one direction.

Typical application categories for this bearing design include:

• Industrial bearing arrangements.

• Shafts in industrial machinery.

• Mechanical gearboxes.

• Industrial drive systems.

• Mechanical assemblies requiring separable cylindrical roller bearings.

These are general applications associated with NJ-type cylindrical roller bearings, not confirmed OEM applications of this specific part number.

Compatibility with a particular machine or gearbox must be established from the relevant engineering documentation.

Installation and Operating Recommendations

The separable construction of NJ412-XL-M1 facilitates the installation of bearing components, but careful handling and cleanliness remain essential.

During installation:

• Verify shaft and housing dimensions.

• Clean the mounting surfaces thoroughly.

• Apply mounting force only to the ring being installed with an interference fit.

• Do not transmit mounting force through the cylindrical rollers.

• Protect raceways and flanges against mechanical damage.

• Provide lubrication suitable for the operating conditions.

• Verify operating clearance after installation.

The open bearing design does not incorporate integral seals to protect against external contamination.

Lubrication and environmental protection must therefore be provided by the complete bearing arrangement.

The lubricant, relubrication intervals, and operating temperature limits should be determined according to the machine design and Schaeffler recommendations.

Frequently Asked Questions - FAQ

What are the dimensions of FAG NJ412-XL-M1?

The bearing has a bore diameter of 60 mm, an outside diameter of 150 mm, and a width of 35 mm. Its principal dimensions are 60x150x35 mm.

What does NJ mean in NJ412-XL-M1?

NJ identifies a cylindrical roller bearing with two integral flanges on the outer ring and one flange on the inner ring. This configuration allows axial loads to be accommodated in one direction.

What does XL mean?

XL identifies Schaeffler's X-life design, incorporating optimised internal geometry and performance characteristics.

What does M1 mean?

M1 specifies a two-piece brass cage guided by the cylindrical rollers.

Does NJ412-XL-M1 have C3 internal clearance?

No. The standard NJ412-XL-M1 configuration without a C3 suffix has normal radial internal clearance, designated CN.

Are NJ412-XL-M1 and NU412-XL-M1 interchangeable?

Not automatically. Although their principal dimensions may be identical, their flange arrangements and axial locating functions differ.

Can NJ412-XL-M1 accommodate axial loads?

Yes. The NJ design can accommodate axial loads in one direction, within the operating limits established for the bearing arrangement.

Is FAG NJ412-XL-M1 supplied pre-lubricated?

It is an open bearing and is not supplied with a factory grease fill intended for normal operation. Suitable lubrication must be provided as part of the bearing arrangement.
