For applications that demand high radial load capacity and speed, NSK N series cylindrical roller bearings provide a robust solution. The design uses cylindrical rollers and a machined bronze cage to deliver rigidity and durability in demanding industrial settings. MR supplies these bearings to customers across the United States, Canada, Mexico and South America.
Reading the N series designation tells you the key features at a glance. The letter N indicates a single row cylindrical roller bearing with two ribs on the inner ring and none on the outer ring, which permits axial displacement between the rings. The number that follows identifies the bore size, and the M suffix denotes a machined bronze cage. This cage construction supports high speeds and adds strength under load.
Typical installations include gearboxes, pumps, fans, compressors and machine tool spindles. The bearings are also found in electric motors and power transmission equipment. Their high radial load rating and inherent rigidity make them a practical choice for metalworking, mining, food processing and power generation facilities.
Selection starts with the radial load, rotational speed and operating environment. Because these bearings are not self-aligning, shaft and housing alignment during mounting is critical. Grease or oil lubrication can be used depending on speed and temperature, and sealing should match the level of contamination present. The bronze cage allows reliable operation at elevated speeds.
If you have a part number from another brand or an unidentified bearing, our team can help identify a compatible NSK N series alternative. Equivalents follow the same international designation, but tolerances and internal clearance should be verified for proper performance.
