Cylindrical Roller Bearings NJ23-ILR for Heavy-Duty Industrial Gearboxes and Construction Machinery

In applications such as vibratory machinery and industrial gearboxes, the basic dynamic load ratings of the bearing and increased strength characteristics of the cage play a particularly important role. Schaeffler has developed, tested, and validated the new NJ23-ILR design in order to meet these requirements.

Product Characteristics of Cylindrical Roller Bearings NJ23-ILR

With the new cylindrical roller bearings of series NJ23-ILR, Schaeffler is introducing a series of rolling bearings for heavy-duty industrial gearboxes and construction machinery. The bearings feature a compact design, are equipped with the high-performance MPAX cage, and have a very high dynamic load carrying capacity. The load rating has been increased by an average of 24 percent, thus doubling the operating life compared to the NJ23 basic type.

Design: NJ

Series: 23

Bore Ø: 80 to 300 mm

Cage: MPAX

Suffix: ILR

Coating: Durotect B available for rings and rollers

Technical Data

How Cylindrical Roller Bearings NJ23-ILR Support You in Your Applications

Increased performance under mixed friction conditions and insufficient lubrication
Highest dynamic load rating and doubled operating life
High-performance MPAX cage with improved strength properties
Interchangeable in accordance with DIN 5412-1
Durotect B coating for increased wear protection (optional)
Doubled operating lifetime helps to reduce CO₂ emissions

Note: The new cylindrical roller bearings with an increased basic load rating replace the LSL range and part of the ZSL range of cylindrical roller bearings (bore code > 15) in the product portfolio.

Areas of Applications for Our Cylindrial Roller Bearings NJ23-ILR

With Schaeffler NJ23-ILR cylindrical roller bearings, almost all the current challenges for rolling bearing technology in the heavy-duty segment can be overcome. The new cylindrical roller bearings from Schaeffler have been adapted to match these increased performance requirements through optimizations in the selection of materials, design, surface quality, and heat treatment.

Solution for construction machinery

The high acceleration forces and heavy vibrations encountered in road construction applications such as soil compressors or vibratory machinery place high demands on the bearing position. NJ23-ILR bearings from Schaeffler make a convincing case with their high load carrying capacity and high level of durability.
