NU 348 M

The NU 348 M is a single row cylindrical roller bearing engineered to handle exceptionally high radial forces. Its "NU" designation signifies a specific design where the inner ring is free of flanges, allowing the bearing to accommodate axial displacement of the shaft relative to the housing in both directions. This feature is critical for applications experiencing thermal expansion or contraction. The rollers and raceways are designed with a logarithmic profile to prevent edge stresses, which significantly enhances the bearing's durability and reliability under heavy load conditions.

A principal advantage of the NU 348 M lies in its robust construction, identified by the "M" suffix, which indicates a machined brass cage. This type of cage offers superior strength and guidance for the rollers, making it exceptionally well-suited for high-speed operation, high temperatures, and environments with significant vibration. The separable design of the NU type bearing, where the inner ring can be mounted independently from the outer ring and roller assembly, greatly simplifies both the mounting and dismounting processes. This practical feature reduces installation time and minimizes the risk of damage during maintenance.

Given its high radial load capacity and ability to manage axial movement, the NU 348 M is a vital component in a wide array of heavy-duty industrial machinery. It is frequently employed in large-scale applications such as industrial gearboxes, rolling mills, and electric motors where substantial radial forces are the primary concern. The bearing's robust design also makes it a reliable choice for the axles of railway vehicles and in construction machinery, where durability and performance under harsh conditions are absolutely essential. The NU 348 M provides a dependable solution for ensuring operational stability and longevity in demanding rotating equipment.
